Uptake of gadoxetic acid in a hepatocellular carcinoma. This coronal image was obtained 15 min after intravenous injection of Gadoxetic acid. (Note that this exam was obtained by a combination contrast technique. This was obtained by first injecting an extracellular gadolinium agent and imaging through the equilibrium phase. This was followed by Gadoxetic acid injection with subsequent hepatobiliary imaging at 15 min.) There are two HCC’s present on this image. The lesion at the dome (black arrow) demonstrates a well circumscribed, hypointense area compatible with the mass without normally functioning hepatocytes. This mass had arterial hyperenhancement and delayed phase washout. These findings are all compatible with hepatocellular carcinoma. The lesion in segment 5–6 (white arrow) is also a hepatocellular carcinoma (same patient as in Figure 1 but it demonstrates uptake of the hepatobiliary agent.
