Abstract

To study the role of MDCT in the evaluation of clinically suspected bowel pathologies. 2) To study the imaging characteristics of various bowel pathologies and narrow down the differential diagnosis using MDCT. 3) To correlate the imaging findings with operative findings/ cytohistopathology/ clinical outcomes if any. 4) To determine the sensitivity, specificity and accuracy of MDCT in the evaluation of bowel pathologies. Material and Methods: 50 patients with suspected bowel pathologies who were referred to the Department of Radiodiagnosis were included in this study. Results: The study had 60% males and 40% females This study showed male predominance. All the 50 patients in the study presented with abdominal pain. Weight loss, fever, vomiting and diarrhoea/constipation were the other complaints by the patients. The predominant wall enhancement pattern was homogenous. We observed that mucosa was affected in maximum number of cases. Based on the length of the bowel maximum cases in our study showed focal involvement. The cases in our study showed equal proportion of the large and small bowel involvement. Maximum cases in our study showed moderate mural thickness. Ascites was present in 88% cases in the present study. Necrotic and non-necrotic nodes were observed in 42% and 38% cases respectively. Pulmonary tuberculosis, liver microabscesses, metastases, peritoneal abscess, diverticulae and ovarian malignancy were the associated abnormalities in our study. On MDCT, tuberculosis followed by the malignancy were the maximum number of cases reported. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of MDCT on diagnosis of tuberculosis was found to be 91.67%, 92.11%, 78.57%, 97.22% and 92.00% respectively. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of MDCT on diagnosis of malignancy found to be 66.67%, 97.56%, 85.71%, 93.02% and 92.00% respectively. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of MDCT on diagnosis of other cases was found to be 100% each. Conclusion: The present study confirms the high diagnostic accuracy of MDCT in bowel diseases. MDCT is a powerful diagnostic tool for the study of bowel disorders, including inflammatory disease, neoplasms, and mechanical obstruction. MDCT enterography is a dedicated technique that allows proper visualization of the entire bowel wall to detect abnormal mural thickening and analyse its type, length, and pattern of enhancement.
