Comparative Accuracy of Colonoscopy, Computed Tomography (CT), and Magnetic Resonance Imaging (MRI) for the Preoperative Localization of Colorectal Cancer: A Prospective Cohort Study

Colonoscopy remains the gold standard for preoperative tumor localization despite its limitations in specific colonic segments. CT offers complementary information, but it was less accurate overall. MRI was a valuable tool for detecting rectal cancer. Future research should focus on improving localization methods, particularly in anatomically challenging areas.
