背景/目的：在一些已发表的报告中，多普勒超声已被用于评估肝动脉的血流灌注。然而，无论是经皮途径还是血管内多普勒方法，都没有足够的验证研究可用。本对比研究的目的是用两种方法评价肝动脉的血流灌注。方法：15例患者在体外用线模型校准多普勒装置后，进行肝右动脉的血管内和经皮多普勒超声检查。结果：在体外，血管内血流速度与血管内血流速度之间的相关性(r=1.0，P
Background/Aims: Doppler sonography has been used to assess hepatic arterial perfusion in a number of published reports. However, adequate validation studies are available for neither the transcutaneous nor the intravascular Doppler approach. The aim of this comparative study was to assess hepatic arterial perfusion with both methods.Methods: In 15 patients the right hepatic artery was examined with intravascular and transcutaneous Doppler sonography after calibration of Doppler devices in vitro with a thread model. The measurements were performed simultaneously in five and separately within 24 h in 10 patients.Results: In vitro, the correlations between the velocities of the thread and the velocities as determined by intravascular (r=1.0, p
