Abstract
PURPOSE: To compare the lesion conspicuity and diagnostic performance of three imaging data sets (T2WI, combined T2WI and DWI [combined DWI], contrast-enhanced (CE)-T1WI) in assessing perianal fistulas. METHODS: Two radiologists with 7 and 15years of experience assessed 28 fistulas from 24 patients in each image set. RESULTS: The lesion conspicuity was improved for only one reader after reading the combined DWI (P=0.0039) and CE-T1WI (P=0.0215). The accuracy was stationary for fistula type (reader 1, all 93%; reader 2, all 89%) or for direction of internal opening (96% for all sets; 92% for CE-T1WI). CONCLUSION: Although combined DWI and CE-T1WI might improve fistula conspicuity, they showed comparable diagnostic performance to T2WI.
