Linear correlation was performed between rCBV, VSIMRI and their corresponding histology value; vessel density and vessel caliber (VSIHistology). Positive linear correlation was found between rCBV vs. vessel density (A, r = 0.42, p = 0.032) as well as between VSIMRI and vessel caliber (D, r = 0.49, p = 0.010). However, no direct relationship was observed between rCBV and vessel caliber (B). VSIMRI measures are independent of vessel density (C). The filled and unfilled circles presenting targets from grade III and grade IV, respectively.
