Perfusion computed tomography in renal cell carcinoma

Figure 2 Perfusion computed tomography in a 63-year-old lady with right renal cell carcinoma (chromophobe type). A: Contrast computed tomography (CT) images show tumor in right kidney (white arrow) with retroperitoneal nodal metastases (arrowhead). Colour-coded perfusion maps show the perfusion parameters; B: Time attenuation curve and perfusion parameters with region-of-interest in the right renal cell carcinoma depict delayed wash-out of contrast. MIP: Maximum peak intensity; TTP: Time to peak; BF: Blood flow; BV: Blood volume; MTT: Mean transit time; PMB: Permeanbility.
