Diagnostic performance and interreader agreement of a standardized MR imaging approach in the prediction of small renal mass histology

The proposed standardized diagnostic approach based on multiple MR imaging features helps identify clear cell and papillary renal cell carcinomas, with accuracy of 81% (88 of 109) and 91% (99 of 109), respectively, while achieving moderate to substantial interreader agreement among many radiologists with diverse clinical experience.
