We created a new imaging technique that detects and emphasizes turbulence, which is a characteristic of blood flow in hepatocellular carcinoma. We devised two indices that determine a characteristic tumor flow, the bi‐directional and low‐peak indices. In the phantom study, both indices of turbulence caused by a stenosis were much higher. In the clinical study, both indices were significantly higher in tumors than in the portal vein or hepatic vein. A turbulent blood flow was detected in 77% of tumors, whereas such detection seldom occurred in the portal or hepatic vein. This technique has the potential to distinguish turbulence in hepatocellular carcinoma. © 1997 John Wiley & Sons, Inc. J Clin Ultrasound 25:183–188, 1997
