Abstract
Objective: In this study our main goal is to evaluate efficacy of MRI in Preoperative Staging of Carcinoma of Rectum.
Method: This prospective observational study was done in the Jalalabad Ragib-Rabeya Medical College, Sylhet from June 2015 to May 2019. A total of 82 consecutive patients who were selected after confirmation with histopathological examination as rectal carcinoma.
Results: During the study, 7.32% (n = 6) of the tumors are classified as T1, 65.9% (n = 54) are staged as T2 and 26.8% (n = 22) as T3 staged by MR .The value of Kw for staging was calculated, in order to determine the correlation between MR versus anatomopathological staging; there is poor agreement between the two forms of staging.
Conclusion: From our study we can conclude that, preoperative staging of carcinoma rectum remains a topic of great concern. The MR imaging can be a valuable technique for preoperative staging of carcinoma rectum in the therapeutic management. Further study is needed for better outcome.
Keywords: Carcinoma Rectum, Magnetic Resonance Imaging (MRI).
