It is imperative to establish normative ranges of aortic diameter to diagnose various aortic pathologies. There have been very few studies establishing the normal aortic diameter on cross‑sectional imaging, and none pertaining to the Indian pediatric population. The objective of this study was, therefore, to establish the normal effective diameter of thoracic aorta at multiple levels using computed tomographic data, calculate z‑scores, and plot reference curves. The effective thoracic aorta diameters (average of anteroposterior and lateral diameters) were measured at predefined levels (aortic root, ascending aorta at the level of right pulmonary artery, aortic arch, proximal descending aorta, and aorta at the level of diaphragmatic hiatus) on double‑oblique reconstructed computed tomography (CT) images perpendicular to the direction of the vessel. Multiple functional forms relating the effective diameter to subjects’ age were evaluated with least square regression methods, and further R2 was used to ascertain the best model. Age‑based formulas to derive normal aorta diameters and mean squared errors (MSEs) were established. Two hundred and seven contrast‑enhanced CT (CECT) thorax studies of children without known cardiovascular disease were studied. The polynomial regression model relating the effective diameter that included linear, quadratic, and cubic age terms as independent variables were found to the best statistical model. The z scores were calculated, and normative curves were plotted. We have established normative effective diameters of the thoracic aorta at multiple levels in Indian children of different age groups. Measurements outside of the normal ranges are indicators of ectasia, aneurysm, hypoplasia, or stenosis.

Indian J Radiol Imaging 2020, 30(1), 163-9.

Few studies have been done for correlating asthma severity, IgE level, and spirometry results with high‑resolution computed tomographic (HRCT) findings in allergic bronchopulmonary aspergillosis (ABPA). This prospective observational study was conducted to correlate asthma severity, IgE level, and spirometry results with HRCT findings in ABPA. Settings and Design: Prospective observational. Fifty consecutive adult patients with asthma and positive specific IgE (>0.35 kUA/L) to Aspergillus fumigatus were recruited from October 2015 to July 2017. Asthma severity, IgE levels, and spirometry results were correlated with HRCT score, bronchiectasis score, air trapping segments, and low‑attenuation lung volume on inspiratory CT and expiratory CT. One way ANOVA, Spearman’s correlation coefficients. Asthma severity showed a significant positive correlation with HRCT score and bronchiectasis score. MEF pre and postbronchodilator values showed a significant negative correlation with HRCT score, bronchiectasis score, and percentage expiratory volumes ‑851 to ‑950 HU voxels. FEV1 prebronchodilator value showed a significant negative correlation with percentage expiratory volume ‑851 to ‑950 HU voxels and percentage expiratory volume ‑851 to ‑1024 HU voxels. Specific IgE antibody level showed a significant positive correlation with bronchiectasis score. Asthma severity, specific IgE level, and MEF values showed a good correlation with HRCT findings. The restrictive pattern is common on spirometry in patients of ABPA. In addition to central bronchiectasis, peripheral bronchial and small airway involvement was an important finding in ABPA. Expiratory HRCT may reveal air trapping in patients having no abnormality on inspiratory CT.

037256 REDDY R (Radiology Dep, Holy Family Hospital, Thodupuzha? 685 605, Kerala, Email: ravikanthreddy06@gmail.com) : MR evaluation of tongue carcinoma in the assessment of depth of invasion with histopathological correlation: A single center experience. Indian J Radiol Imaging 2020, 30(1), 126-38.

Magnetic resonance imaging (MRI) has become the cornerstone for pretreatment evaluation of carcinoma tongue and provides accurate information regarding the extent of the lesion and depth of invasion that helps the clinician to optimize treatment strategy. Aim of the study is to correlate MRI and histopathological findings, to evaluate the role of MRI in loco‑regional tumor node metastasis (TNM) staging, and to assess the depth of invasion of tongue carcinoma. This study was undertaken on 30 patients with clinical diagnosis of tongue carcinoma referred for MR imaging at a tertiary care hospital over the 2‑year period between July 2017 and June 2019. MRI was performed with GE 1.5 Tesla scanner, neurovascular (NV) array coil. Clinical and MRI staging of tongue carcinoma was done preoperatively and correlated. Post‑surgery, histopathological TNM staging was done and correlated with clinical and MRI TNM staging.The cutoff value of histopathological (HP) depth that could determine the existence of nodal metastasis was 5 mm. In 30 patients diagnosed with tongue carcinoma, the incidence was higher in males (92 %). Moderate agreement (k = 0.512) was noted for T staging between clinical and MRI staging assessments. Fair agreement (k = 0.218) was noted for N stage between clinical and MRI staging assessments. There was good agreement (k = 0.871) for M stage between the clinical and MRI staging assessments. Good agreement (k = 0.822 and k = 0.767, respectively) was noted for both T staging and Nstaging between MRI and histopathology staging assessments. The agreement for the T stage was poor (k = 0.012) between the clinical and histopathology staging assessments. Agreement for the N stage was also poor (k = 0.091) between the clinical and histopathology staging assessments. Mean depth of invasion by histology and MRI was 14.22 mm and 16.12 mm, respectively. Moderate agreement (k = 0.541) was noted between clinical and pathological tumor depth and good agreement (k = 0.844) was noted between radiological and pathological tumor depth. As for the T1WGd MRI depth with a cutoff value of 5 mm, the nodal metastasis rate in the group with values >5 mm was 52 %, and for those <5 mm was 24 %, both of which were significantly different (P = 0.040). Pearson’s correlation coefficient of HP depth and T1WGd MRI depth was 0.851 (P < 0.001) suggesting that HP depth shows a strong correlation with T1WGd MRI depth. MRI is the imaging modality of choice for evaluation of tongue carcinoma as MRI helps in accurate staging of the tumor using TNM classification which is crucial for optimizing treatment options. The current study shows a high correlation between MRI and histopathological findings regarding thickness of tumor and depth of invasion. MRI and histopathology assessments of tumor spread were equivalent to within 0.5 mm DOI. Estimation of invasion depth using MRI as a preoperative study in oral tongue carcinoma is essential in planning surgical treatment strategies such as the extent of elective neck dissection. Invasion depth, which greatly affects occult node metastases, must be included in the TNM staging of oral tongue carcinoma.

037254 CHACKO A, VEDAJALLAM S, ANDRONIKOU S, SIMPSON E, THAI N J (Bristol Univ, United Kingdom, Email: anithchacko@gmail.com) : Accuracy of radiologists, nonradiologists, and laypeople for identifying children with cerebral cortical atrophy from “Mercator map” curved reconstructions of MRIs of the brain. Indian J Radiol Imaging 2020, 30(1), 111-5.

Using text reports to communicate bilateral, symmetric, and zonal cortical brain atrophy in children with term hypoxic ischemic injury (HII) to parents and legal professionals contesting compensation rights can be difficult. Using standard cross‑sectional images for explaining bilateral, regional brain imaging to laypeople is also challenging. A single flattened image of the brain surface, much like a map of the earth is derived from a globe, can be generated from curved reconstruction of magnetic resonance imaging (MRI) scans, i.e., a Mercator map. Laypeople’s ability to identify abnormal “Mercator brain maps,” without prior training, requires evaluation before use in nonmedical settings. To determine the sensitivity and specificity of laypeople in detecting abnormal pediatric Mercator flat‑earth maps of the brain, without prior training. 10 Mercator brain maps were provided to 111 participants individually. The maps comprised 5 HII, 1 cortical dysplasia, and 4 normal cases. Participants were required to identify the abnormal scans. Sensitivity and specificity overall and for participants’ subgroups were calculated. Overall sensitivity and specificity were 67 % and 80 %, respectively. General radiologists (n = 12) had sensitivity and specificity of 91.2 % and 94.6 %, respectively. Laypeople (n = 54) had a sensitivity of 67 % and specificity of 80 %. The high specificity and sensitivity of radiologists validated the technique for distinguishing abnormal scans, regarding cortical pathology. High specificity of laypeople for identifying abnormal brains using Mercator maps indicates that this is a viable communication tool for demonstrating cortical MRI abnormalities of HII in children to laypersons.

Insights into obtaining FRCR and beyond: Obstacles, opportunities and post?relocation dilemma – An Indian perspective

THAKER S, BOTCHU R, GUPTA H

037253 THAKER S, BOTCHU R, GUPTA H (Musculoskeletal Radiology Dep, The Royal Orthopedic Hospital, UK, Email: drbrajesh@yahoo.com) : Insights into obtaining FRCR and beyond: Obstacles, opportunities and post?relocation dilemma – An Indian perspective. Indian J Radiol Imaging 2020, 30(1), 70-6.

Indian radiology trainees and radiologists are interested to have FRCR (Fellow of the Royal College of Radiologists) qualification for various reasons including academic career progression, subspecialty interest and other socioeconomic factors. The path for acquiring FRCR qualification is adventurous yet onerous and exhausting. Perseverance, meticulous planning and clarity in the vision are essential prerequisites for an Indian graduate aiming to complete FRCR qualification, and one may require to invest an average of 1.5–2 years even if there is no reattempt in this tripartite examination. Indian doctors including radiologists are considered amongst the finest across global medical fraternities. However, the Indian medical education is skewed and variably distributed over the subcontinent due to organisational inability to provide single radiology curriculum‑based education to all radiology training programmes. Parallel educational boards and a variety of institutions such as government, trust‑funded and private organisations provide radiology training to further complicate the grand picture of radiology education in India. Conversely, UK radiology education is uniform nationally and rigorously enforced by deaneries based upon state‑provided guidelines. UK training opportunities are essentially academically rewarding experience but they require herculean efforts to gain access to one. One should constantly focus on building a resume at par with that of a UK trainee by obtaining experience required to fulfil checklist for such opportunities. Alongwith addressing local (UK) competition thoughtfully, hard work, diligence, and high standards of work ethics are absolute musts to build a great resume, to obtain training opportunity and, in turn, to satisfy the ultimate goal of carrier advancement.

Indian J Radiol Imaging 2020, 30(1), 32-45.

Infertility is a major social and clinical problem affecting 13–15 % of couples worldwide. The pelvic causes of female infertility are categorized as ovarian disorders, tubal, peritubal disorders, and uterine disorders. Appropriate selection of an imaging modality is essential to accurately diagnose the aetiology of infertlity, since the imaging diagnosis directs the appropriate treatment to be instituted. Imaging evaluation begins with hystero‑ salpingography (HSG), to evaluate fallopian tube patency. Uterine filling defects and contour abnormalities may be discovered at HSG but usually require further characterization with pelvic ultrasound (US), sono‑hysterography (syn: hystero‑sonography/saline infusion sonography) or pelvic magnetic resonance imaging (MRI), when US remains inconclusive. The major limitation of hysterographic US, is its inability to visualize extraluminal pathologies, which are better evaluated by pelvic US and MRI. Although pelvic US is a valuable modality in diagnosing entities comprising the garden variety, however, extensive pelvic inflammatory disease, complex tubo-ovarian pathologies, deep‑seated endometriosis deposits with its related complications, Mulllerian duct anomalies, uterine synechiae and adenomyosis, often remain unresolved by both transabdominal and transvaginal US. Thus, MRI comes to the rescue and has a niche role in resolving complex adnexal masses, endometriosis, and Mullerian duct anomalies with greater ease. This is a review, based on the authors’ experience at tertiary care teaching hospitals and aims to provide an imaging approach towards the abnormalities which are not definitively diagnosed by ultrasound alone.

Indian J Radiol Imaging 2020, 30(1), 27-31.

High perinatal mortality in India may be caused by inaccurate dating of pregnancy resulting from suboptimal uptake of antenatal care and ultrasound services during pregnancy. To determine the discrepancy in the last menstrual period (LMP) assigned expected date of delivery (EDD) and ultrasound assigned EDD in pregnant women in a rural district of central India. Data from an ongoing cross‑sectional screening program providing fetal radiology imaging in Guna district of Madhya Pradesh from 2012–2019 was analyzed for recall of LMP and discordance between LMP and ultrasound assigned EDD. The discrepancy was present when EDD assigned by ultrasound differed by 3 or more days at gestational ages less than 8+6 weeks, 5–7 days at gestational ages 8+6 weeks till 14 weeks, and 7–10 days at gestational ages 14–20 weeks. The program screened 14,701 pregnant women of which 4,683 (31.86 %, 95 % CI: 31.11, 32.61) could not recall LMP. EDD assigned by LMP and ultrasound matched in 7,035 (70.22 %, 95 % CI: 69.32, 71.12) of the remaining 10,018 pregnant women. EDD was overestimated by LMP for 26.06 % (95 % CI: 25.21, 26.93) women; these foetuses were at risk of being misclassified as a term fetus. In 2018, the project had no maternal deaths, infant mortality rate of 24.7, low birth weight rate of 9.69 %, and 100 % antenatal coverage. Conclusion: Accurate dating of pregnancy and systematic follow‑up integrating radiology imaging and obstetrics care for appropriate risk‑based management of pregnant women can significantly improve perinatal statistics of India.

Indian J Radiol Imaging 2020, 30(1), 20-6.

Chemotherapy while revolutionizing cancer management by improving survival and quality of life; is also associated with several adverse effects. Lung is the most common organ affected in chemotherapy‑related complications, due to either drug toxicity or more commonly due to infections caused by immunosuppression and less commonly due to immune‑mediated injury. Radiology, when used in combination with clinical and lab data, can help reach the specific diagnosis or narrow down the differentials. The common radiological patterns of drug toxicity include pulmonary interstitial and airway infiltrates, diffuse alveolar damage, nonspecific interstitial pneumonia, eosinophilic pneumonia, cryptogenic organizing pneumonia, pulmonary hemorrhage, edema and hypertension. Cancer patients are immunosuppressed due to the underlying malignancy itself or due to therapy and are prone to a gamut of opportunistic infections including viral, bacterial, fungal and mycobacterial pathogens. Immune reconstitution inflammatory syndrome (IRIS), a well‑known complication in HIV, is now being increasingly recognized in non‑HIV patients with immunosuppression. Engraftment syndrome is specifically seen following hematopoietic stem cell transplant during neutrophil recovery phase. Pulmonary involvement is frequent, causing a radiological picture of noncardiogenic pulmonary edema. Thus, radiology in combination with clinical background and lab parameters helps in detecting and differentiating various causes of pulmonary complications. This approach can help alter potentially toxic treatment and initiate early treatment depending on the diagnosis.

037244 GUPTA N, MAHAJAN S, SUMANKUMAR A, SAKLANI A, ENGINEER R, BAHETI A D (Radio Diagnosis Dep, Tata Memorial Hospital, Maharashtra, Email: akshaybaheti@gmail.com) : Impact of a standardized reporting format on the quality of MRI reports for rectal cancer staging. Indian J Radiol Imaging 2020, 30(1), 7-12.

Besides providing a surgical roadmap, rectal MRI plays a major role in treatment planning. We recently started using a structured template for reporting rectal cancer via MRI. We study the impact of using this template at our hospital in terms of number of essential imaging parameters described in the reports as compared to the pre‑template free‑text reports. A structured rectal MRI reporting template was created in consensus with members of the colorectal tumour board and was introduced in the department, which included 14 essential parameters to be mentioned in the reports. We conducted a retrospective analysis of rectal MRI reports of 100 cases with histologically proven rectal cancer, comprising 50 consecutive free‑text reports before the template was introduced and 50 consecutive structured reports after its introduction, checking for the presence or absence of inclusion of the 14 parameters. An anonymous online feedback survey was conducted as well after the introduction of the template for the members of the colorectal tumour board. Overall, the total number of parameters reported increased from a median value of 10 (range 6‑13) to 14 (range 12‑14). The common unreported parameters prior to template introduction included T staging, presence or absence of restricted diffusion, anterior peritoneal reflection (APR) involvement, and presence or absence of extramural vascular invasion; these were reported in 16 %, 22 %, 30 % and 50 % respectively. These improved to 98‑100 % reporting after template introduction. Maximum improvement was in T staging (16 % to 98 %) (P < 0.0001), restricted diffusion on DWI (from 22 % to 100%) (P < 0.0001) and APR involvement (from 30 % to 100 %) (P < 0.0001). The most common unreported parameter after template introduction was the “tumoral T2 signal intensity” (unreported in 4 % cases). The results of the survey were as follows: 100 % felt a decreased need to talk to the radiologist to clarify the report, 81.8 % felt an improvement in the quality of reporting as compared to free style reports, and 91 % felt that the new template is easier to interpret. The introduction of a structured template for rectal cancer significantly improved the quality of rectal MRI reports, along with the satisfaction of referring providers.

Indian J Vet Sci Biotechnol 2020, 16(1), 66-8.

This study was conducted in the Barabanki district of Uttar Pradesh on reproductive disorders in cattle and buffaloes under field conditions. The information was generated from 120 farmers, 20 farmers from each of six selected villages, who had at least one milking dairy animal at the time of the investigation. The information was generated regarding reproductive disorders of indigenous cattle, crossbred cattle, and buffalo due to improper feeding, breeding, and healthcare management practices and was analyzed to explore the incidence rate of reproductive disorders faced by dairy farmers in three categories of animals. The overall incidence rate of reproductive disorders among indigenous cattle, crossbred cattle, and buffalo in the area surveyed revealed maximum incidence in buffalo (76.05 %) and minimum in indigenous cattle (48.77 %), the crossbreds being intermediate (72.62 %). Late maturity was the major problem in indigenous cattle and anoestrus in buffalo. The incidence of repeat breeding was the highest in crossbred cattle. Dystocia, prolapse and stillbirth were more in buffaloes, while abortion, RFM, and uterine infections were more in crossbred cattle. Reproductive disorders like dystocia, prolapse, abortion and stillbirth were mostly treated by veterinarians; however, remaining reproductive disorders like anoestrus, repeat breeding, uterine infection etc. were treated by dairy farmers and quacks through their own experiences by using different type of indigenous technical knowledge. There is a need to create awareness about scientific animal husbandry practices among dairy farmers of the region studied.

Indian J Vet Sci Biotechnol 2020, 16(1), 44-8.

This study investigated the effect of weaning age on carcass characteristics of crossbred piglets reared up to 70 kg body weight (BW) under intensive system. A total of 24 piglets were used in a completely randomized design. The experiment comprised three treatments: piglets weaned at 21, 28, and 35 days of age with four replicates each with two piglets (castrate and female). At 70 kg BW two piglets (castrate and female) were randomly selected from each replicate and sacrificed for carcass evaluation. Hot carcass weight (HCW) was measured and thereafter dressing out percentage was calculated. Carcasses were chilled at 7 0C for 24 hours to determine cold dressed weight (CDW). Carcasses were cut into the left and right halves along the median line. The left half of the carcass was used to measure carcass length (CRLTH), average backfat depth and longissimus muscle area (LMA) at the 10th rib, while the right half of the carcass was physically dissected into bone, muscle and fat and thereafter tissue ratios calculated. Longissimus muscle was removed at the 10^th and 11^th ribs from the left half of the carcass for chemical composition analysis. Data were analysed using General Linear Model. Weaning age had no influence (p > 0.05) on HCW, dressing percentage, CDW, CRLTH, average backfat thickness, average backfat depth, LMA and carcass lean percentage. No significant differences (p > 0.05) were observed on average percentages of bone, muscle and fat tissue and their tissue ratios. Weaning age did not influence (p > 0.05) moisture, protein, fat and ash contents of the meat. In addition, weaning age had no (p > 0.05) effect on carcass characteristics, physical and chemical body composition of meat. These results indicate that piglets can be weaned at 21, 28 and 35 days of age without detrimental effects on carcass characteristics, physical and chemical body composition of pork.

037229 RAJALEKSHMI C, MISHRA R K, SAVALIYA F P, PATEL A B, LUNAGARIYA P M, BHAGORA N J (Anand Agricultural Univ, Anand, Email: rkmishra@aau.in) : Effects of dietary supplementation of essential oils as an alternative to antibiotic growth promoter on performance of commercial broilers. Indian J Vet Sci Biotechnol 2020, 16(1), 11-6.

An experiment was conducted to assess the effects of thyme and peppermint essential oils (EO) as an alternative to antibiotic growth promoter (AGP) on the performance of broiler chicken. Total 256 day-old Vencobb broiler chicks were randomly distributed into eight experimental groups with four replicates of eight birds each. Experimental groups were fed with control diet without supplementation of AGP and essential oils (T1), BMD (Bacitracin Methylene Disalicylate) antibiotic @ 500 mg/kg diet (T2), thyme essential oil @ 150 mg/kg diet (T3), 200 mg/kg diet (T4), 250 mg/kg diet (T5), peppermint essential oil @ 200 mg/kg diet (T6), 250 mg/kg diet (T7) and 300 mg/kg diet (T8). The supplementation of thyme oil @ 200 mg/kg and peppermint oil @ 300 mg/kg broiler diet significantly (p <0.05) improved b.wt. and b.wt gain. The peppermint oil supplementation @ 300 mg/kg was found to be more beneficial when compared among different oil-supplemented groups. The feed conversion ratio was significantly (p < 0.05) improved with peppermint oil supplementation @ 300 mg/kg diet. A significant (p < 0.05) reduction in the mean abdominal fat was observed in diet supplemented with higher levels of thyme oil (@ 250 mg/kg diet) and peppermint oil (@ 300 mg/kg diet). Return over feed cost was the highest in broilers assigned diet with AGP; however, it was statistically similar to the basal diet. Considering the net return over fed cost of broilers, use of thyme oil was uneconomical, but supplementation of peppermint essential oil @ 200 and 300 mg/kg diet increased the net return over feed cost and were economical, however less as compared to T1 and T2.

Group-I cows were administered on the day of calving with a sustained release 80 g mega mineral rumen bolus (Prepavel® 1 bolus/animal, Neolait, France) intra-ruminal through a specially designed applicator, while group-II animals served as untreated control. The animals were monitored periodically from the day of calving till 140 days postpartum along with other herd mates. Blood samples were obtained at 10 days interval in heparinized vacutainers for plasma progesterone, biochemical, and macro-micro mineral profiling. Among the six Kankrej cows of group-I, only one animal exhibited prominent estrus signs on day 96 postpartum and conceived at first service (AI) giving CR of 16.66 %, while in group-II three cows exhibited estrus between day 73 and 86 postpartum, and conceived with one or two AI giving CR of 50 % by 150 days postpartum. In both the groups, all other cows remained subestrus for more than 150 days postpartum and conceived very late, though mostly with single service at spontaneous estrus. The mean values of plasma progesterone (0.74 ± 0.32 to 5.57 ± 0.78 ng/mL), total cholesterol (103.88 ± 3.20 to 237.17 ± 24.66 mg/dL) and triglycerides (17.07 ± 1.16 to 28.29 ± 1.75 mg/dL) differed significantly (p < 0.01) between postpartum intervals in both the groups, but not between groups at any of the intervals. The values of plasma total protein, calcium, inorganic phosphorus, and magnesium as well as trace elements, viz., zinc, iron, copper, cobalt, and manganese, however varied insignificantly and inconsistently between intervals and also between groups from day 0 to day 140 postpartum. Thus, the insertion of Mega mineral ruminal bolus on the day of calving did not influence the plasma profile of biochemical/ metabolic constituents and macro-micro minerals profile in lactating postpartum Kankrej cows and was not beneficial in improving postpartum fertility. However, further study on a larger sample size is required to draw a valid conclusion.
