[Diagnostic imaging of hepatic tumors].
There are several imaging methods for the detection of small hepatocellular carcinomas (HCC). The combined use of computed tomography (CT) and angiography is an excellent method. CT following intraarterial injection of iodized oil is a sensitive and useful examination for the detection of small hypervascular HCCs. CT during arterial portography is superior in visualizing small hypovascular HCCs. These methods are complementary to each other. Magnetic resonance imaging (MRI) is a new examination. T1 and T2 of the HCC are usually longer than normal hepatic parenchyma. HCCs greater than 2 cm are almost detected by MRI.
