Objective: To probe the blood supply of liver metastasis by celiac arteriography, proper hepatic arteriogaphy, pure portal vein perfusion CT.
Methods: Fifty patients with liver metastasis were examined prospectively by plain CT scan, multiphase enhanced CT scan, celiac arteriography and proper hepatic arteriography, of whom, 23 were examined by pure portal vein perfusion CT during superior mesenteric arterial portography. The imaging manifestations were observed, and the time attenuation curves (TDC)of tumor center, tumor edge, portal vein and normal liver parenchyma were used to calculate liver perfusion with a software of PhotoShop(used in DSA image analysis)and a deconvolution model (CT perfusion software) designed for the dual blood supply.
