Abstract: Background: There is a lack of consensus about whether the initial imaging method for patients with suspected nephrolithiasis should be computed tomography (CT) or ultrasonography. Material and Methods: This is a Prospective, descriptive and single centre study. A total of 90 patients’ USG and CTU were compared for the presence of calculi in the Department of Radiology, Maheshwara Medical College and Hospital. Sensitivity, specificity, accuracy, positive predictive value and negative predictive value of USG were calculated with CTU as the gold standard. Results: From the 90 sets of data collected, the sensitivity and specificity of renal calculi detection on USG were 53% and 85% respectively. The mean size of the renal calculus detected on USG was 6.8 mm ± 3.8 mm and the mean size of the renal calculus not visualized on USG but detected on CTU was 3.5 mm ± 2.7 mm. The sensitivity and specificity of ureteric calculi detection on USG were 12% and 97% respectively. The sensitivity and specificity of urinary bladder calculi detection on USG, were 20% and 100% respectively. Conclusion: This study showed that the accuracy of US in detecting renal, ureteric and urinary bladder calculi were 68%, 80% and 99% respectively.
Abstract: Introduction: Radiation in medicine has brought improvements in quality of diagnosis as well as treatment of patients notwithstanding its deleterious side effects. The study is aimed at evaluating the effectiveness of structural shields in X-ray facilities. Materials and method: This was a prospective cross-sectional study aimed at assessing the adequacy of the existing structural shields in the selected facilities using NCRP 49 methodology. The target population for this study was selected X-ray facilities in Asaba, designated centre A to F. Ethical approval was granted by the Ethical and Research Committee of Federal Medical Centre Asaba. The dimensions six X-ray rooms were measured using a 7.5m/25ft measuring tape. Average technical parameters of 100kVp and 60mAs at a distance of 180cm from the tube head to the erect bucky with 30cmx30cm collimation were used. A well calibrated Inspector USB survey meter was used to measure dose rate in mR/hr and a NT6200 electronic dosimeter to measure the equivalent dose (mSv). To validate the result, three exposures were taken and the mean readings recorded. The data was analysis using SPSS for Windows, Version 22.0 (SPSS Inc., Chicago, IL, USA). Descriptive statistics was used to determine mean values. Result: The average workload in this study was 42mA-min/week. The barrier ..........
Abstract: We aim to analyze the difference in themean fetal cisterna magna length in second trimester among the consanguineous and non-consanguineous marriages in Indian population, in this retrospective cross sectional study. Study was carried out in the Department of Radiology, Sree Balaji Medical College and Hospital, Chennai, from November 2017 – November 2019. A total of 1067 patients in their second trimester (18–24 weeks of gestation) were included in this study (740 Non consanguineous and 327 consanguineousmarriages). Anteroposterior measurement of Fetal Cisterna magna was measured in the axial plane of the fetal head, at the level of transverse cerebellar diameter , from the posterior aspect of cerebellar vermis to inner table of the occipital bone in midline. Mean cisterna magna length was 4.28 mm in consanguineous marriages and 4.29 mm in non consanguineousmarriages. There is no significant difference in mean fetal cisterna magna length inconsanguineous marriages and non consanguineous marriages in this period of gestation. No article in literature has compared the cisterna magna length with consanguineous and non consanguineous marriages.
Abstract: Macleod syndrome is an obstructive pulmonary disease linked to the anatomical sequelae of acute viral bronchiolitis in childhood. We report an observation of a patient with a clear unilateral lung in order to discuss the diagnostic approach and to underline the difficulty of the aetiological research.
Abstract: To assess the severity of acute pancreatitis (AP) using computed tomography (CT) severity index (CTSI) and modified CT severity index (MCTSI), to correlate with clinical outcome measures, and to assess concordance with severity grading, as per the revised Atlanta classification (RAC). Material and Methods: This is a prospective and descriptive study conducted in the Department of Radiology at a Maheshwara Medical College. A total of 50 patients enrolled with the chief complaint of epigastric pain, nausea and vomiting and CECT abdomen were suggestive of acute pancreatitis were included in this study. Assessment of severity of acute pancreatitis was done in all cases by Balthazar CTSI scoring and Mortele Modified CTSI scoring. Results: In our study total 50 cases of acute pancreatitis cases were included in the study. Out of 50 cases, 36 (72 %) were male and 13 (26%) were females. We found that acute pancreatitis was found three times more common in males than in females. Cholelithiasis was found to be most common aetiological factor for acute pancreatitis in 48% cases followed by alcoholic pancreatitis was seen in 26% of cases. Least Aetiological factor such as Trauma and drug induced. Pleural effusion was the most common extra-pancreatic complication, 27 patients (54%). Left pleural effusion was more common than the right, and in none of the cases, isolated right sided pleural effusion was found. Ascites was the second most common complication seen in 9 patients (18%). Conclusion: In conclusion CECT was found to be an excellent imaging modality for diagnosis, establishing the extent of disease process and in grading its severity. The Modified CT Severity Index is a simpler scoring tool and more accurate than the Balthazar CT Severity Index. In this study, it had a stronger statistical correlation with the clinical outcome, be it the length of hospital stay, development of infection and occurrence of organ failure. It could also .....................

Abstract: Calcifications of the prostate are frequent and benign. They are not linked to any particular symptom or disease. They are not precursors of prostate cancer. We evaluated in 78 patients, the characteristics of these calcifications and their prevalence according to the presence of urinary symptoms.
Abstract: Background: Nonalcoholic fatty liver disease ranges from simple steatosis, steatohepatitis—to advanced fibrosis and cirrhosis. It has great significance in medical practise as an increasingly recognized condition globally. Early detection and quantification to prevent its sequelae is necessary. Aims: We are keen to investigate minimally invasive technique to bring for the clinicians, a socio-economic issue of importance to the field of Radiology. Objective: To compare ultrasound with MRI for the diagnosis of liver steatosis. Methods: A prospective study was carried out at Radiology Department, IDC. Study duration: November 2018 - May 2019. 86 participants, aged 14-86 years, of either gender, with suspicion of steatosis were selected, after satisfying inclusion and exclusion criteria. Steatosis was confirmed utilizing Complex-based technique with MRI. For ultrasound, conventional sonographic signs criterion was used. Results: 88 consecutive patients, (43 females and 45 males) mean age (48.88 years). MRI-PDFF revealed steatosis grade 0 (normal) in 40.9% cases, 35.2%, 18.2% and 5.7% in grade 1, 2 and 3 accordingly. While ultrasound revealed grade 0 in 26.1% cases and 44.3%, 25% and 4.5% in each respective grade. Sensitivity of ultrasound amplified as amount of hepatic fat gradually increased, from 58.33% (minimal steatotic cases) to 93.75% and 100% respectively (moderate to severe cases). Specificity remained between 73.68% to 98.82% throughout all cases. Conclusion: Ultrasound correlated well with MRI in moderate to severe hepatic steatosis, with mild degrees its specificity is reduced owing to other causes of liver injuries. Subjects practising unhealthy diet, hypertensive plus diabetics are more prone to develop steatosis. Thus its an acceptable modality for steatosis diagnosis, if severity/grading is neglected.
