Figure 4b. Late arterial phase contrast-enhanced CT images in a patient with arterioportal shunts, telangiectases, and large confluent vascular masses. (a) Transverse MIP and (b) three-dimensional MIP reconstructed images show the hepatic arteries and portal and hepatic veins to be already enhanced. Despite the heterogeneous parenchyma, the presence of three large confluent vascular masses (arrows) and multiple telangiectases (arrowheads) is evident.
