Clinical Application and Study of Computed Tomography Arterial Portography in the Diagnosis of Liver Cancer

Zeng Meng-(?)u,Wang Bin,Zhou Kang-rong.Department of Radiology,Zhongshan Hospilal,SMU 200032  
Clinical application of computed tomography arterial portography(CTAP)in the diagnosis for metastatic and primary liver cancer was reported by only few authors in the recent years. This technique was performed in 25 patients in our hospital in order to evaluate the sensitivity and compare it systematically with other imaging modalities.The results showed that in 15 cases of small hepatocellular carcinoma with the number of 21 lesions confirmed by surgicopathology,the sensitivity of CTAP reached up to 90.5%(19/21)for lesion≤3.0cm and 75%(6/8)for lesion≤1.0cm,much higher than that of other imaging modalities.CT appearances and mode of portal vein supply of hepatocellular carcinoma on CTAP were discussed.We got final conclusion that CTAP was the most sensitive technique in detection of small lesions(diameter≤1.0cm,esp.)and should be considered in very suspicious and selective cases.
