Abstract: | OBJECTIVE: To evaluate the role of hepatic arterial phase (HAP) spiral computed tomography (CT), as compared with iodized oil (Lipiodol ultrafluid LUF]) CT for revealing nodular hepatocellular carcinomas (HCC). METHODS: Twenty-four cirrhotic patients underwent two-phase HCT examination: HAP 25 seconds and portal phase 70 seconds after injection of 1.5 mL/Kg contrast medium. All patients also underwent hepatic angiography and intraarterial infusion of iodized oil; LUF CT was performed 3-4 weeks after infusion. HCT images were compared with LUF CT images for detection of hepatic nodules. RESULTS: We found no significant difference between the sensitivity of HAP CT and LUF CT for nodules >10 mm, while HAP CT was more sensitive than LUF CT in revealing nodules <10 mm (47 vs. 27, p < 0.001). CONCLUSIONS: HCT should be considered as the first method for the detection of HCC, whereas LUF CT should be used only for therapy. |
