TO STUDY THE CT CHARACTERISTICS OF WALL THICKENING IN CASE OF BENIGN AND MALIGNANT LESIONS OF THE COLON AND RECTUM.
Keywords:CT, Benign, Malignant & Rectum.
Background & Method: This is a prospective study conducted in the Department of Radio Diagnosis, Shyam Shah Medical College, Rewa (M.P). In this study, patients with wall thickening involving the colon and rectum on CT were included. CT was performed using Idohexol contrast medium. All patients were placed in the supine position on the CT table, and a rectal tube was inserted. Room air was gently insufflated into the colon get adequate colonic distension.
Result: There was involvement of the entire length of rectum in 30 % of the cases. Caecum, ascending colon, transverse colon, descending colon and sigmoid colon was involved in 20% of the cases. Rectum was the most common region to be involved (47.5%) followed by the sigmoid colon (27.5%). Four lesions showed involvement of both the sigmoid colon and the rectum (10%) and one lesion showed involvement of both the caecum and the ascending colon(2.5%).
Conclusion: MDCT is an excellent modality in the diagnosis and differentiation of benign and malignant lesions of the colon and rectum, since it has the advantage of providing thinner sections, faster acquisition and multi planar reformatted images.
