Thirteen hepatic tumors(6 metastatic liver tumors, 2 cholangiocellular carcinomas, 3 hemangiomas and 2 abscesses) in which efferent blood flow signals were detected by color Doppler imaging, were evaluated in this study. A total of 19 efferent color flow signals were detected in 13 hepatic tumors. Eighteen out of 19 signals showed a continuous waveform pattern and the remaining 1 signal showed a venous waveform pattern. Thirteen out of 19 efferent signals were shown to be connected to the portal vein branch and 2 signals were shown to be connected to the hepatic vein. Fourteen out of 19 efferent signals were associated with pulsatile waveform signals, which were considered to be feeding the artery adjacent to the efferent vessel. In conclusion, color Doppler flow imaging is useful in detecting efferent blood flow signals in hepatic tumors other than hepatocellular carcinoma, which is not readily available with any other modalities.
