Comparison of Contrast-Enhanced Multiphase Renal Protocol CT Versus MRI for Diagnosis of Papillary Renal Cell Carcinoma

Abstract

A small number of pRCCs have indeterminate enhancement when renal protocol CT is used. Heterogeneity, irregular margins, and calcification are suggestive diagnostic features; however, quantitative and qualitative CE-MRI can accurately differentiate hemorrhagic/proteinaceous cysts from pRCC.
