Role of magnetic resonance imaging in evaluation of perianal fistulas

Abstract

ABSTRACT The term “fistula in ano” refers to an aberrant track connecting the anal canal with the perineum and is one of the common anorectal disorders. [1] It is a common disorder that affects both men and women with male predominance and can cause substantial discomfort and pain. Therefore the effective management of a perianal fistula is crucial to avoid complications, including abscess development, incontinence, and recurrence. Identification of the fistula’s internal opening, the primary source of cryptoglandular infection, the path of the primary track, and the location of any secondary tracks or abscesses are all crucial for effective fistula care.MRI(Magnetic resonance imaging) of the pelvis is the preferred imaging modality to detect and evaluate perianal fistulas due to its high spatial resolution and multiplanar capabilities, which provide exquisite details of the pelvis.
