Figure 3:

Representative T2-weighted image and quantitative maps (apparent diffusion coefficient [ADC], renal blood flow [RBF] [ie, perfusion], T1, and T2) for two high-grade renal cell carcinomas (RCCs) (arrows; aggressive neoplasms). Images and maps in (A) a 68-year-old female participant with a grade 3 RCC and (B) an 83-year-old female participant with a grade 4 RCC. Histologic images with hematoxylin and eosin stain at 20× magnification are also presented. The region of interest for each tumor is delineated by the white outline in the inset indicated by the dashed line. The mean and SD of the quantitative values extracted from the region of interest analysis are shown at the bottom of the maps. Although similar mean RBF and ADC values were obtained for the two RCCs, distinct T1 and T2 values were observed.
