CT Perfusion in the Characterisation of Renal Lesions: An Added Value to Multiphasic CT
Figure 1
CTp of clear cell RCC: ROI 1, ROI 2, and ROI 3 were drawn in the aorta, tumour, and healthy ipsilateral renal cortex, respectively (a-b). The PS values of the tumour and normal cortex were 42.90 mL/100 g/min and 67.64 mL/100 g/min, respectively, whereas MTT values were 13.73 sec and 3.59 sec, respectively (b). Lesion size was 20 mm. Histopathology: morphology, haematoxylin, and eosin (c) and CD34 stain (d); original magnification: 50x.
