We attempted to visualize tumor blood flow by overlaying the tumor outline on 3-D color Doppler images. The equipment used was the Toshiba SSA-270A with a probe (3.75 MHz) installed on the 3-D position detecting arm. A hepatocellular carcinoma with a diameter of 40 mm was discovered. 3-D color Doppler images reveal the blood flow around the tumor; however, it is difficult to distinguish between the intra- and the extra-tumor blood flow without observing the tumor's outline. By overlaying the outline onto 3-D blood flow images, we can clearly distinguish between the intra- and the extra-tumor blood flow. This method is considered to be useful for observing the relationship between a tumor and the surrounding vessels.
