ABSTRACT
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
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
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
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, Dr. VRK Women’s Medical College, Teaching Hospital and Research Centre. 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
Abstract: Introduction: Brain abscess is a life threatening disease that present a formidable challenge to the physicians. Despite the development of effective antibiotics & modern surgical techniques significant mortality & morbidity persist among patients with CNS infections. Aim of the study: To assess the CT scan findings, sensitivity and specificity of CT scan in the diagnosis of brain abscess. Material & Methods: This cross sectional consecutive observational study was conducted at the Department of Radiology and Imaging of Rajshahi Medical College Hospital from January, 2018 to December, 2018. Fifty-five (55) patients were selected using consecutive, non-randomized and open sampling method considering the inclusion and exclusion criteria. All the relevant data were collected, compiled and then organized by standard appropriate statistical formulae. Statistical analyses of the results were obtained with Statistical Packages for Social Sciences (SPSS-13). Statistical tests for significance of difference were done using t test, chi square test, or 'Z. test where applicable. A 'p' value < 0.05 was considered as significant. For Z test of proportion window based computer software devised with MINIT AB-12 was used. Results: The age range was from 11 to 65 years and the mean ±SD age was 34.18±16.81 years. Statistical analysis of patients of both sex has revealed that they were within similar age distribution (p value= 0.385). Single lesion was present in 83.6% patients and 16.4% had multiple lesions in the brain. 94.5% patients had abscess in gray-white matter junction and rests had within white matter. A total 52.7% patients had brain abscess on right cerebral hemisphere followed by 43.6% on left hemisphere and 3.6% had on cerebellum. 94.5% lesions were hypodense on CT and rests had both hypo and isodense feature. Ring enhancement and surrounding edema were the most common characteristic CT features in the diagnosis of brain abscess. Conclusion: Culturally and cyt
