Abstract

T2WI alone for preoperative T categorization by less- Purpose: This retrospective study aimed to assess the experienced reader and DWI could be used for preop- value of adding diffusion-weighted magnetic resonance erative T categorization and for predicting the imaging (DWI) or gadolinium-enhanced fat-suppressed histopathologic grade of renal pelvic carcinoma. T1WI (CEI) to T2-weighted imaging (T2WI) for preop- erative T categorization in renal pelvic carcinoma by the Key words: Renal pelvic carcinoma—Contrast-enhanced reader’s experience using surgical specimens as the imaging—ADC value—DWI—1.5T MRI—Urothelial reference standard. carcinoma Methods: Two radiologists (Reader 1; 3 years, 2; 13 years) reviewed 49 cases with urothelial carcinoma who underwent magnetic resonance imaging examina- Abbreviations tion before surgery, independently, using three image DWI Diffusion-weighted magnetic resonance sets: T2WI alone, T2WI plus DWI, and T2WI plus CEI imaging for tumor detection and T categorization. The differ- CEI Gadolinium-enhanced fat-suppressed ences in the apparent diffusion coefficient values between T1-weighted imaging tumors and renal parenchyma, histopathologic grade DCEI Dynamic contrast-enhanced imaging were analyzed. T2WI T2-weighted imaging Results: T2WI plus CEI or DWI had high detection rates MRI Magnetic resonance imaging (93.4%) compared to T2WI alone.
