[ Summary ] Recently, a great deal of progress has been made in imaging modalities for hepatocellular carcinoma including multidetector-row CT, MR imaging and ultrasonography. The second generation contrast agents for sonography, Sonazoid, and gadolinium-ethoxybenzyl-diethylene triamine (Gd-EOB-DTPA), which are liver-specific MR contrast agents, have also become clinically available. These new contrast agents provide functional imaging of hepatocellular carcinomas such as Kupffer cell and hepatocyte functions in addition to morphology, vascularity and diffusion-weighted imaging, resulting in great advances in diagnostic accuracy for hepatocellular carcinomas. Gd-EOB-DTPA enhanced MR imaging, provides both dynamic and liver-specific images and is particularly useful for the diagnosis of early hepatocellular carcinoma as well as hypervascular hepatocellular carcinoma. It can also be utilized for surveillance of hepatocellular carcinoma in combination with ultrasound as a non-invasive imaging technique.
