Abstract
The purpose of this study was to retrospectively compare contrast-enhanced fat-suppressed T1-weighted images with histopathologic findings in ureteral carcinoma to develop accurate preoperative MR criteria for T staging.
Contrast-enhanced fat-suppressed T1-weighted images can be used to distinguish thickened noncarcinomatous ureteral walls, which occur due to the proliferation of fibrous tissue, from ureteral carcinoma because fibrous tissue enhances more intensely on MRI than ureteral carcinoma. We also observed that when ureteral carcinomas had invaded periureteral fat tissue, a disruption or fragmentation of the intensely enhancing ureteral wall was seen. Using the MR criteria for T staging that we developed on the basis of these findings, we were able to accurately determine whether a carcinoma had invaded periureteral fat tissue in all of our patients.
