目的:用彩色多普勒血流显像法与彩色多普勒能量图来比较对照肝癌合并门静脉瘤栓内血流的情况。方法:先用二维超声检查出肝癌及门静脉瘤栓形成的部位,分别用血流显像和能量图检测出栓子内的血流。结果:28例肝癌合并门静脉瘤栓患者,用血流显像法检出瘤栓内动脉血流信号8例,用能量图检出14例。结论:彩色多普勒显像与彩色多普勒能量图比较,能量图更能准确地显示肝癌合并门静脉瘤栓内的血流。
Objective: To compare the blood flow in control liver cancer with portal vein tumor thrombus using color Doppler flow imaging and color Doppler energy imaging. METHODS: The location of hepatocellular carcinoma and portal vein tumor emboli was first examined with two-dimensional ultrasound, and the blood flow within the embolus was detected with blood flow imaging and energy imaging. RESULTS: In 28 cases of hepatocellular carcinoma with portal vein tumor embolus, 8 cases of intra-arterial blood flow signals were detected by blood flow imaging, and 14 cases were detected with an energy chart. Conclusion: Compared with color Doppler energy imaging, energy imaging can more accurately show the blood flow in hepatocellular carcinoma combined with portal vein tumor thrombus.
