The perianal fistulae are complex clinical scenarios, often complicated by direct or blind surgical exploration. A precise preoperative evaluation of the perianal fistulous tract is not only an essential diagnostic requirement but a presurgical prognostic determinant. The usefulness of Magnetic Resonance Imaging (MRI) in such instances is established, but if aqueous jelly can be used instead of regular contrast during fistulography is not clear. Aim: To evaluate the diagnostic accuracy of

... ic Resonance (MR) percutaneous aqueous jelly compared to intravenous (i.v.) contrast enhanced MR fistulography in perianal fistulous tracts. Materials and Methods: A prospective cohort study was carried out on 40 participants who were referred for MR fistulography (with suspected anal fistulae) to the
