The purpose of this study was to compare power Doppler sonography with conventional color Doppler sonography for the detection of the vascularity of hepatocellular carcinomas after transcatheter arterial chemoembolization. Of the 93 embolized hepatocellular carcinomas, hypervascularity was demonstrated in 36 on angiography; power Doppler sonography correctly identified pulsatile flow signals in 33 (92%) of these 36, whereas color Doppler sonography identified flow signals in 24 (67%). A statistically significant difference was noted when the sizes of the nodules were 30 mm or less. Despite technical difficulties, such as flash artifact, power Doppler sonography is superior to color Doppler sonography for detection of hypervascularity, especially in small embolized nodules of hepatocellular carcinoma (30 mm or less in diameter).
本研究的目的是比较能量多普勒超声与传统彩色多普勒超声在经动脉化疗栓塞后检测肝细胞癌血管方面的效果。在93个接受栓塞治疗的肝细胞癌中，血管造影显示36个存在高血供；能量多普勒超声在这36个中的33个（92%）正确识别出搏动性血流信号，而彩色多普勒超声在24个（67%）中识别出血流信号。当结节大小为30mm或更小时，差异具有统计学意义。尽管存在诸如闪烁伪像等技术难题，但在检测高血供方面，能量多普勒超声优于彩色多普勒超声，尤其是在直径30mm或更小的栓塞性肝细胞癌小结节中。
