ABSTRACT

Objective: To assess the diagnostic accuracy of magnetic resonance imaging (MRI) in the evaluation of perianal fistula when compared to surgical findings and identify any factors that may affect the accuracy  (MRI) in identifying (perianal fistula) as will determine the positive and negative likelihood ratios, sensitivity and specificity of MRI in diagnosing perianal fistula and  calculate the area under the summary receiver operating characteristic (ROC) curve for MRI in diagnosing perianal fistula.

Study Design: Non-probability consecutive sampling method

Place and Duration of Study: This study was conducted at the Department of Radiology. Hayatabad Medical Complex, Peshawar Jan 2020 to Jan 2021.

Materials and Methods: After receiving informed consent, a (1.5 Tesla) superconducting magnet with an external coil was used to provide MR imaging. The SPSS version 22 was used to input and evaluate the data.

Results: In our study, out of 85 patients, the patient's average age was (44.36±15.55) years, and the male-to-female patient ratio was 01.03:01. The sensitivity, specificity, and diagnostic precision of MRI were 93%, 92%, and 92%, respectively, using surgical findings as the gold standard.

Conclusion: Our study shows that MR imaging is a dependable and accurate method for identifying perianal fistulas, with high sensitivity and specificity, using surgical findings as the gold standard.

Key Words: Magnetic resonance imaging, surgery, evaluation, and perianal fistula
