The Value of Abnormal Hepatic Perfusion in the Diagnosis of Hepatic Abscess / 实用放射学杂志

ABSTRACT

Objective To research the diagnostic value and the relative factors of abnormal hepatic perfusion in hepatic abscess. Methods During February 1998~ October 2003, spiral scan was perfomed in 34 patients with hepatic abscess, of which 34 patients with hepatocellular carcinoma 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 hepatic perfusion of hepatic abscess were analyzed. Results Abnormal hepatic perfusion in arterial phase was seen in 26 cases, of which 18 cases in hepatic abscess and 8 cases in hepatocellular carcinoma, presenting as irregular patchy high density. CT demonstrated that formation of abnormal hepatic perfusion was related to the course of diseases, but not related to the location of the lesions. Conclusion Abnormal hepatic perfusion is another important enhanced CT sign and is valuable in the diagnosis of hepatic abscess.
