Proposed Modifications to the Multiparametric CT Score for Diagnosis of ccRCC Using Hyperattenuation, Segmental Enhancement Inversion, and ADER: A Secondary Analysis

In a secondary analysis of 148 small (≤ 4 cm) solid renal masses, none of three CT features (hyperattenuation on unenhanced images, segmental enhancement inversion, or arterial-to-delayed enhancement ratio) significantly improved the performance of a multiparametric CT score for the diagnosis of clear cell renal cell carcinoma.
