The nodules appeared hypoperfused compared to the surrounding liver parenchyma during this phase and were diagnosed as malignant with CEUS. (B) Portal phase of CEUS of another dog with hepatocellular carcinoma showing small intralesional vessels (arrows). The nodules appear hypoperfused compared to the surrounding liver parenchyma during this phase and were diagnosed as malignant. 3A 3B Figure 3.

(B) CEUS image (left) in the arterial phase of the same lesion as shown in Figure 3A and corresponding gray-scale image (right). Note the perilesional vessel creating a ring-enhancement pattern (arrow). The nodule appeared hypoperfused compared to the surrounding liver parenchyma on the portal phase of CEUS.
