Continuous waves were detected in 33 of 71 (46%) lesions from 61 patients with hepatocellular carcinoma as proven by histologic findings. The color signals of continuous waves were classified into 3 types namely, feeding signal (FS) , spotty signal (SS) , and drainaging signal (DS). FS is a signal entering into the tumor from the boundary, SS is spotty or short linear signal in the tumor, and DS is a signal flowing out of the tumor. In 8 lesions smaller than 2 cm in diameter, FS was detected in 4 lesions, SS in 3, and DS in 1 lesion. In 12 lesions less than 4 cm in diameter, FS was detected in 2 lesions, SS in 4 and DS in 6. In 13 lesions larger than 4 cm, SS was detected in 3 and DS was in 10. Compared with the angiographic findings, it is suggested that FS represents a feeding portal vein and DS shows a draining vein.
