Background: MRI examination of the rectum has evolved as the standard technique in the assessment of cancer rectum having multiplaner capabilities and high tissue contrast imaging. The aim of this study: The aim of this study is to evaluate the role of MRI in assessment of rectal neoplasm. Patients and methods: In this study we prospectively evaluated 40 patients (24 male -60%) and (16 females -40%), who referred to the MRI unit, Radiology department, (Minia Oncology Center) for further assessment of histopathology proven rectal carcinoma, during the period of (August 2019 ) to (August 2021). Results: 10% of patients (4 participants) had high rectal cancer while 55% of them (22 patients) had middle rectal cancer. On the other hand, 35% of them (14 patients) had low rectal cancer. 85% of participants (34 patients) were diagnosed as adenocarcinoma while the remaining 6 participants (15% of patients) were diagnosed as mucinous adenocarcinoma. 77.5% of patients (31 participants) had grade II rectal cancer while 9 patients (22.5% of participants) were diagnosed as grade III rectal cancer. On performing TNM staging, we found that the majority of cases; 37.5% of participants (15 patients); were found to be in stage IIA.
