Abstract:
Objective To evaluate the diagnostic value of spiral CT [CT arterial portography (CTAP) and CT hepatic arteriography(CTHA)] for hepatic carcinoma. Methods The CTAP and CTHA manifestations in 21 patients with hepatocelluar carcinoma were analyzed and compared with those in three-phase enhanced CT . Results The detection rate of three-phase enhanced CT was 72.4% , CTAP and CTHA was 96.1% and 88.2% respectively. The detection rate of combination CTAP and CTHA was 98.7% . They could reveal tumors of 0.5 cm in diameter . Both CTAP and CTHA gave false-positive findings , such as perfusion defects in 22.3% of CTAP and non-pathologic enhancement in 30.2% of CTHA .Conclusion With the use of spiral CT technique , the quantity of contrast material administrated in CTAP and CTHA can be considerably reduced . And the quality of CT images significantly improved . The detection rate of CTAP and CTHA is higher than that of three-phase enhanced CT . Simultaneous use of both procedures may decrease the false-positive rate.
