Recent advances in imaging techniques of renal masses

Figure 4 Computed tomography perfusion images (A-C) reveal a significant difference in permeability and mean transit time values between normal renal cortex and malignant lesions. Mean transit time (MTT) and permeability (PMB) in normal renal cortex were 10.48 s and 55.56 mL/100 mL/min, respectively, which were significantly different from those of renal cell carcinoma (RCC) (MTT: 9.06 s; PMB: 237.09 mL/100 mL/min). A cut-off of 2.5 mL/100 g/min yielded a 100% sensitivity and 95.92% accuracy to predict RCC.
