Introduction: Polyps are fibro vascular extensions of mucosa into bowel lumen. Radiological assessment plays a major role in depicting colonic polyps. Colonoscopy is a gold standard technique to detect polyps with high sensitivity and specificity. Magnetic Resonance (MR) Colonography is also an even less invasive method without any ionizing radiation.
Aim: This study designed to compare the efficacy of MR Colonography with conventional colonoscopy in colonic polyps.
Materials and Methods: A total 42 patients with chief complaints of bleeding per rectum and familial background of colonic polyps were recruited. 200 mL of peglec solution, five times for every 15 minutes was administered for bowel cleansing. All the cases were undergone for MR Colonography and Conventional Colonoscopy.
Results: MR Colonography showed sensitivity 82.04%, specificity 84.66%, positive predictive value 93% and negative predictive value 61%. Conventional colonoscopy showed sensitivity 88%, specificity 92.54%, Positive predictive value 96.02% and Negative predictive value 48%.
Conclusion: MR Colonography has moderate sensitivity and specificity than conventional colonoscopy. Patient acceptance of MR Colonography was less when compared to conventional colonoscopy.
