Computed tomography detection of small daughter nodules in hepatocellular carcinoma after iodized oil infusion into the hepatic artery.
The detectability of small daughter nodules of hepatocellular carcinoma by computed tomography after hepatic arterial infusion of Lipiodol (iodized oil) and by infusion hepatic angiography was studied in 102 cases. The Lipiodol was selectively accumulated by the tumor. Tumors and small daughter nodules appeared as high-density areas on computed tomography. In 24 cases daughter nodules were identified only by computed tomography. In 50 cases computed tomography demonstrated superior ability to detect the daughter nodules when compared with infusion hepatic angiography. In 21 cases the daughter nodules were detected for the first time in areas other than the main site of the primary tumor. Lipiodol-computed tomography is very effective in the diagnosis of daughter nodules of hepatocellular carcinoma.
