Thirteen nodules in 13 patients with chronic liver disease were diagnosed as hypovascular nodules through the use of ultrasound (US) angiography under intraarterial carbon dioxide microbubbles.
Histological diagnosis of these 13 cases included adenomatous hyperplasias, borderline lesions, and well-differentiated hepatocellular carcinomas. In this study, the relationship between tumor growth speed and portal per fusion within these nodulaes was evaluated by comparing tumor doubling time (DT) and the findings of CT during arterial portography (CTAP). The mean DT in three nodules with a perfusion defect on CTAP was 170±73 days, whereas that in 10 nodulae without a perfusion defect on CTAP was 583±207 days (P
