It’s difficult to differentiate intrarenal transitional cell carcinoma from centrally located renal cell carcinoma by contrast enhanced CT when the tumor composition is complex. In this study, DTI were performed to investigate the utility of the apparent diffusion coefficient (ADC) and fractional anathtropy (FA) values for differential diagnosis of ccRCC and infiltrative TCC, thus assessing the sensitivity and specificity of ADC and FA values. The FA value from DTI, which reveals the different structure of tumors, provides an effectively non-invasive means to distinguish ccRCC from TCC because of its good sensitivity.
