Abstract:
Objective To study CT findings and relative factors of abnormal liver perfusion in hepatocellular carcinoma(HCC).Methods During October 1998～February 2001, spiral CT scan was perfomed in patients with HCC, of which 51 with and 51 without portal carcinomatous embolus were randomly selected. Following plain spiral CT scan of the liver, arterial phase scanning was started at 20 s, after contrast injection. CT findings were observed and the relative factors of abnormal liver perfusion of HCC were analyzed.Results Abnormal liver perfusion in arterial phase was seen in 28 cases, presenting as irregular patchy high density. CT demonstrated that formation of abnormal liver perfusion was related to location of tumors, existing of portal embolus and location of portal embolus.Conclusion Arterial phase spiral CT scanning is helpful in detecting the abnormal liver perfusion and accurately judging the extent of the tumors. This information is helpful to clinical treatment.
