Abstract

PURPOSE: To evaluate the diagnostic efficacy of computed tomography (CT) after hepatic intraarterial injection of iodized oil in patients with hepatocellular carcinoma (HCC). MATERIALS AND METHODS: Forty patients who underwent CT with iodized oil before orthotopic liver transplantation (OLT) were evaluated prospectively. All patients underwent digital subtraction angiography and injection of iodized oil during chemoembolization. CT during arterial portography (CTAP) was performed in 34 patients. The number of neoplastic nodules was assessed in explanted livers and compared with the radiologic results. RESULTS: Sixty-six HCC nodules were present in the explanted livers. CT with iodized oil enabled correct diagnosis in 38 of 66 lesions (58%), and the results were false-positive in two lesions (3%). Digital subtraction angiography had a sensitivity of 67% (44 of 66 nodules) and CTAP had a sensitivity of 85% (45 of 53 nodules). Four (6%) false- positive diagnoses were made at digital subtraction angiography and three (6%) at CTAP. The diagnostic efficacy of CT with iodized oil was significantly related to lesion diameter greater than 2 cm (P <.0001) and hypervascularity (P <.0001). CONCLUSION: CT with iodized oil failed to provide any substantial information in the pre-OLT staging of HCC: It was inaccurate for small HCC nodules (
