[Computerized tomographic diagnosis of hepatocarcinoma after injection of lipiodol into the hepatic artery].
Iodized oil (lipiodol) injected into the hepatic artery is selectively retained by hepatocarcinomas, as demonstrated by computerized tomography (CT) performed one week after the injection. The value of this technique for the diagnosis of hepatocarcinoma was assessed in a retrospective study of 45 patients. In 39 per cent of the cases intrahepatic tumoral extension was determined by the iodized oil which showed tumoral nodules that had not been detected by conventional methods, such as ultrasonography and CT alone. The lesions revealed by the iodized oil were small nodules around the main tumour. The combined iodized oil-CT technique plays an important role in the choice of treatment, especially when surgical excision is contemplated. It might also contribute to an early diagnosis of hepatocarcinoma in patients at risk, as illustrated by four of our cases where conventional morphological examinations had been negative.
