MRI is considered the de facto imaging modality for evaluating perianal fistulas, primarily due to its excellent soft tissue contrast, operator independence, multiplanar capabilities and excellent field of view. Tridimensional endoanal ultrasound (3D-EAUS) is inferior to MRI in identifying and/or evaluating ischiorectal/supralevator tracks/extensions and therefore could end up providing incomplete and even inaccurate information (e.g. misclassification of tracks) to the surgeon, with a missed track potentially leading to recurrence of the disease.
