OBJECTIVE: It has been suggested that @entity292 in ano is most accurately assessed using endoanal receiver coils because they provide superior spatial resolution. We aimed to determine their advantage by prospective comparison with conventional body coil imaging. SUBJECTS AND METHODS: Thirty consecutive unselected @entity1 with a diagnosis of @entity295 were examined by MR imaging with an endoanal coil. Imaging with a body coil followed. Imaging was independently evaluated by two radiologists who classified @entity292 according to the coil used and then compared their findings, which were validated surgically. RESULTS: Five @entity1 could not tolerate coil insertion. In the remaining 25 @entity1 , endoanal imaging revealed no abnormalities in three @entity1 in whom the body coil image correctly showed @entity30 , a sinus, and a transsphincteric @entity292 . Imaging with both coils revealed @entity295 in 16 @entity1 , allowing radiologists to make correct primary track classification in 13 @entity1 on endoanal imaging compared with 15 @entity1 on body coil imaging. Endoanal imaging revealed 10 secondary extensions in eight @entity1 , but further extensions in two of these @entity1 and in a third @entity1 were undetected. All these extensions were seen on body coil imaging. Overall, surgical concordance was 68% for endoanal imaging compared with 96% for conventional body coil imaging. CONCLUSION: Due to field-of-view limitations, endoanal imaging is less accurate than conventional body coil imaging for preoperative assessment of complex anal @entity292 .
