Radiologists and clinicians should exert much caution during the procedures in such patients. This study was done to study the anatomical variation of the colon in abdominal CT scans and correlated the variations with gender. \u0000Methods: It was a cross-sectional study done at the Department of Radiology and Imaging of Manipal Teaching Hospital from September 2020 to March 2021. Abdominal CT was obtained and colonic position was evaluated. The Chi-square test was applied to assess the correlation between colonic variations and gender. \u0000Results: There were 388 patients in total. The age of the patients ranged from 3 years to 94 years. The mean age of the patients was 44.8±18.6 years. There were 166 (42.8%) females and 222 (57.2 %) males. Out of 388 patients, 170(43.8) had some colonic anatomical variations. Sixteen (4.1%) patients had retro gastric colon. Around 6% had a right retrorenal colon and 30(7.7%) had a left retrorenal colon. Seven (1.8%) patients had anterolateral hepatodiaphragmatic interposition. Forty-two patients (10.8%) had high positioned caecum. The redundant sigmoid colon was present in 38(9.8%) patients. There was no significant correlation between the colonic variation and gender. \u0000Conclusion: Different variations in the colon exist even in the Nepalese population, of which the radiologists, as well as the surgeons, should be aware.","PeriodicalId":178516,"journal":{"name":"Nepalese Journal of Radiology","volume":"357 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131556698","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It helps in determining the mode of delivery and aids in diagnosing low birth weight, macrosomia, and intrauterine growth restriction fetus. Ultrasound may not be available in under-resourced settings. Therefore, it is important to study the accuracy of clinical estimation of fetal weight with the sonographic and actual birth weight. \u0000Methods: One hundred and fifty women fulfilling the inclusion criteria were enrolled for the study. Clinical estimation of fetal weight was done by using the Johnson formula. Then the women were subjected to ultrasound. Sonographic estimation of fetal weight was done by the Hadlock method. The two estimated fetal weights were then compared with the actual birth weight. Data were analyzed using SPSS (VERSION 16). \u0000Results: Actual birth weight has a strong correlation with the ultrasonographic birth weight (p=0.01). However, the clinical birth weight estimation was less correlating to the actual birth weight (p=0.638) \u0000Conclusion: The ultrasound method is better in determining the actual birth weight as compared to the clinical method. Hence, ultrasound has to be recommended whenever available.","PeriodicalId":178516,"journal":{"name":"Nepalese Journal of Radiology","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130854431","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Space available for the cord (SAC) can be used as an indicator of spinal stenosis. \u0000 Methods: This study was performed on patients referred for MRI examinations of the cervical spine for various clinical indications to a tertiary centre in Nepal. Data were collected for a period of four months from January to April after IRB approval. Convenience sampling was employed and a total of 72 examinations were included. Data were obtained from the 1.5T Magnetom Amira Siemens MRI scanner. Sagittal diameters of the spinal canal and spinal cord were traced and measured from C3 to the C7 vertebra.

The MRI findings were noted i.e. disc desiccation, disc bulge (diffuse, symmetrical and asymmetrical), disc protrusion, neural foramen narrowing, traversing nerve root compression, exiting nerve root compression and posterior annular ligament tear.\u0000Results: Out of 98 patients enrolled in the study mean age being 41 years.

This study was an attempt to quantify the diagnostic quality of chest radiographs by evaluating the quality of depiction of the anatomical details as well as other technical factors.\u0000Method: A total of 450 chest radiographs, produced at Tribhuvan University Teaching Hospital, were selected for study over two months period.
