Figure 1. Two illustrative cases for selection of ROI location (~1 cm diameter).
(a) A ROI was placed in the well-enhancing part in left renal clear cell carcinoma in a 37-year-old female patient. The total microvascular density was 313.08/mm2. (b) A ROI was placed in left renal cell carcinoma in a 46-year-old female patient. This part was only slightly enhanced. The total microvascular density was 54.74/mm2.
