Abstract

Aim. Investigation of possibilities of magnetic resonance imaging as a whole, as well as different modes of MR scanning (without intravenous contrast, with intravenous contrast, with the use of diffusion-weighted imaging) in the diagnosis of cryptogenic fistulas of the rectum.

Materials and methods. In the study were included 50 patients with cryptogenic fistulas of the rectum (21 women and 29 men). All patients underwent magnetic resonance imaging of the pelvic organs.

Results. The sensitivity of MRI in the diagnosis of the primary fistulas was 100%. With regard to secondary fistulas MRI sensitivity was 91.7%, specificity was 94.3%. The sensitivity of MRI in the diagnosis of chronic abscesses paraproctitis was 82.6%, specificity was 95.2%. The sensitivity of the method in the visualization of internal opening was 95.5%, specificity was 80.0%. The sensitivity of the method in the diagnosis of external openings was 91.7% and specificity was 100%. In the analysis of separates MR scanning mode we didn’t find statistically significant differences between them (p < 0.05).

Conclusions. Magnetic resonance imaging has a high diagnostic efficacy in the diagnosis of cryptogenic perianal fistulas. We didn’t find statistically significant differences between MR scanning modes.
