Diagnostic Accuracy of Magnetic Resonance Imaging in Perianal Fistula Taking Surgical Findings as Gold Standard

Aim: To determine the diagnostic accuracy of magnetic resonance imaging (MRI) in perianal fistula taking surgical findings as gold standard Study design: Cross Sectional Study. Place of study: Radiology Department, Sheikh Zayed Hospital, Lahore. Methods: The non-probability consecutive sampling technique was used in this study. After taking the informed consent the MR imaging was done using a 1.5 Tesla superconducting magnet with external coil. All the data was entered and analyzed on SPSS version 17. Results: In our study the mean age of the patients was 44.36 +/- 15.55 years, the male to female ratio of the patients was 1.3:1. The sensitivity, specificity and diagnostic accuracy of MRI was 92.94%, 91.76% and 92.35% respectively taking surgical findings as gold standard Conclusion: It has been proved in our study that the MR imaging is reliable and accurate procedure for detecting perianal fistula taking surgical findings as gold standard with high sensitivity and specificity.
