The characteristics of three-dimensional angiography of hepatocellular carcinoma on 64-slice spiral CT scan

Objective To explore the characteristics and clinical values of three-dimensional angiography of hepatocellular carcinoma (HCC) on 64-slice spiral CT scan. Methods CTA was performed on 63 cases of clinically and pathologically confirmed HCC by a 64-slice spiral CT. CT images were analyzed using three-dimensional reconstruction techniques including maximum intensity projection (MIP), multiplanar reformation (MPR), and volume rendering (VR). Results In the arterial phase, there were 46 (73.0%) regular blood supply to the tumor, 12 (19.0%) variable blood-supply, and 1 (1.6%) parasitic blood supply, and the remaining 4 were unidentified. The artery supplying blood to the tumor was enlarged in 22 cases and shifted in 19 cases. Tumor vessels were found in 39 cases, tumor stain in 48 cases, arteriovenous fistula in 12 cases; 13 cases revealed tumor thrombi in the portal vein stage. Conclusions Three-dimensional angiographiy with 64-slice spiral CT not only accurately locates tumors, but also offers multiple angles to view the solid relationship between the tumor and the target vessel, providing valuable information for the clinical diagnosis and treatment.
