Abstract
High resolution magnetic resonance imaging plays a pivotal role in the pretreatment assessment of primary rectal cancer and post operative follow up. Rectal cancer constitutes about one third of all gastrointestinal tumor so, high resolution MRI is the best modality to assess the relations of the rectal tumor and the potential circumferential resection margin (CRM). Therefore it is currently considered the method of choice for local staging of rectal cancer and follow up post total mesorectal excision (TME) operations. Objective: The purpose of this study was to assess the accuracy of MRI in the preoperative staging, prediction of negative circumferential resection margin, planning of surgical management and post operative follow up of rectal carcinoma
