本研究的目的是在人体新鲜标本的体外定量评价的贡献的水相内膜界面(第一个400毫秒的反射信号)在正常和动脉粥样硬化动脉壁。研究了75个样本,15个正常,15个脂肪,15个纤维脂肪,15个纤维,15个钙化。使用宽带换能器(4至14 MHz)。水相-内膜反射(以dB表示,平均值+/- SD)在脂肪斑块中最低(-35.3 +/- 2.5),与所有其他组的差异非常显著:正常(-13.2 +/- 8.8)、纤维脂肪(-20.4 +/- 8.3)、纤维(-13.0 +/- 9.7)、钙化(-5.9 +/- 3.4)。在正常和脂肪样本中,来自内膜-中膜过渡区的回声幅度相对较低;通常,来自内膜-中膜过渡区的强反射存在于其他病理子集中。总之,动脉壁的时域回波模式可以提供斑块结构的有用线索。
The aim of this study in vitro of human fresh specimens was to quantitatively evaluate the contribution of the aqueous phase-intima interface (the first 400 msec of the reflected signal) in normal and atherosclerotic arterial walls. Seventy-five samples were studied, 15 normal, 15 fatty, 15 fibrofatty, 15 fibrous, and 15 calcific. A broadband transducer (4 to 14 MHz) was used. The aqueous phase-intima reflection (expressed in dB, mean +/- SD) was lowest in the fatty plaques (-35.3 +/- 2.5), differing in a highly significant way from that in all other groups: normal (-13.2 +/- 8.8), fibrofatty (-20.4 +/- 8.3), fibrous (-13.0 +/- 9.7), calcific (-5.9 +/- 3.4). The echo coming from the intima-media transition was of relatively low amplitude in normal and in fatty samples; typically, strong reflections from the intima-media transitions were present in the other pathologic subsets. In conclusion, the time domain echo pattern of the arterial wall may provide a useful clue to the structure of the plaque.
