A high-resolution ultrasound B-mode imaging system combined with a 16-sequential range-gated pulsed Doppler flow measuring device was used for the evaluation of nonstenotic extracranial carotid artery disease. Various types of atherosclerotic lesions were differentiated by Duplex system examinations in 54 carotid arteries examined in vitro in a postmortem study and in 51 carotid arteries examined in vivo from patients with angiographically proven cerebrovascular disease. In addition, the multigated Doppler system allowed the analysis of flow velocity profiles throughout the carotid arteries, the distinction between intraarterial flow and recent thrombus, and in particular the estimation of local flow alterations, which are diagnostic in the presence of sonolucent and shadowed plaques behind echo-dense lesions. A number of difficulties, which at present limit the application of Duplex system examination as a non-invasive "stand alone" method for detecting carotid disease, are discussed.
一种结合了16序列距离选通脉冲多普勒血流测量装置的高分辨率超声B型成像系统被用于评估非狭窄性颅外颈动脉疾病。在一项尸检研究中对54条离体颈动脉以及对51条来自血管造影证实患有脑血管疾病患者的活体颈动脉进行了双功系统检查，以此区分各种类型的动脉粥样硬化病变。此外，多门控多普勒系统能够分析整个颈动脉的血流速度剖面，区分动脉内血流和近期血栓，特别是能够估计局部血流改变，这在回声致密病变后方存在透声和有阴影的斑块时具有诊断意义。本文还讨论了目前限制双功系统检查作为检测颈动脉疾病的非侵入性“独立”方法应用的一些困难。
