VEGFA and liver cancer: According to our results, the CT perfusion imaging-related parameters and serum VEGF and BFGF in patients with primary liver cancer were significantly different from those in patients with benign liver lesions, and the CT perfusion parameters and serum VEGF and BFGF levels in patients with different stages of primary liver cancer were different, which was because blood of foci in primary liver cancer is mainly supplied by the hepatic artery with especially fast flow velocity, thereby increasing the pressure [19, 20].
