CT or MRI Which is better for Rectal Cancer Imaging?

Abstract

Colorectal cancer is one of the common causes of cancer-related mortality with rectal cancer representing a significant proportion. Cross-sectional imaging techniques especially computed tomography (CT) and magnetic resonance imaging (MRI) play an important role in preoperative staging of rectal cancer. There has always been a debate about the single best imaging modality for staging of rectal cancer in order to achieve the best surgical outcome. Hence, this article focuses on the comparative role of CT & MRI in staging of rectal cancers.
