Resultsįour articles that complied with all inclusion and exclusion criteria were selected for data extraction and analysis (n = 248 lesions in 266 patients). In addition, a summary receiver operating characteristic (SROC) analysis was performed. MethodĪfter a systematic review of the available literature, studies were included that reported b-values, used a histopathological reference standard, and allowed construction of 2 × 2 contingency tables for detection of RCC lesions using DW-MRI. We sought to determine the comparative diagnostic performance of standard b-value (800–1000 s/mm 2) versus low b-value (400–500 s/mm 2) diffusion-weighted magnetic resonance imaging (DW-MRI) in the detection of renal cell carcinoma (RCC).
