Colonoscopy is the gold standard for polyp detection: Sensitive and specific. Colorectal cancer diagnosis may benefit from magnetic resonance colonography (MRC), a less invasive approach. This research compared MR Colonography to colonoscopy for colonic polyps.

Material and Methods: A total of thirty-eight individuals, aged 21 and above, who presented with rectal bleeding as their main symptom and had a family history of colonic polyps, were included in the study. To perform colon cleansing, a 200ml dose of peglec solution was administered 5 times at 15-minute intervals. Every patient had both MR Colonography and traditional Colonoscopy.

Results: Both radiographic methods had a sensitivity of 24 true positive, 8 false positive, 2 false negative, and 4 true negative for lesion detection. The study's findings on lesion detection showed a sensitivity of 80.32%, specificity of 83.98%, positive predictive value of 91.04%, negative predictive value of 67.6%, and diagnostic accuracy of 81.34%.

Conclusion: MR colonography was essential in identifying cases when conventional colonoscopy was unable to reach the caecum. Because it does not need any intrusive procedures, MRC is a very effective substitute for traditional methods of screening for colorectal cancer.
