Nandini Bahri MD, Abstract Co-Author: Nothing to Disclose

After reviewing of this article, readers will: To differentiate the early stages of carcinoma like T1 and T2 from mucosal thickening, collapsed rectum, and polyp. To plan the coronal images perpendicular to axial images in distended rectum to avoid partial volume effect and to accurately evaluate the depth of tumor and length of tumor for surgery.  To see the distensibility and delineate the intact mucosa in case of lesions like lymphoma and GIST of recto-sigmoid junction  

Introduce nearly 100 ml sterile aqueous jelly in the rectal lumen and use surface array coils to do MRI for rectal pathologies. The advantage of jelly: Water based contrast with or without gadolinium requires pressure effect like foley’s bulb to be retained in the rectum up to the completion of MR examination and that causes impact on the ability of MRI to detect the exact distance between tumor and potential resection margin. And patients with abdominal discomfort shows very low compliance to this technique. While jelly distends the rectum optimum enough to visualize the lumen and help to differentiate the above mentioned rectal pathology without giving false impression of potential resection margin as there is no pressure effect required and patient compliance is high as there is no need to distend entire large colon.
