We have evaluated the efficacy of using three-dimensional reconstruction of amplitude Doppler imaging data to quantitatively assess carotid artery bifurcation stenoses.
Sixty-four consecutive frames of amplitude (power) Doppler images are stored to be reassembled into a three-dimensional image representing the patent lumen. These images can then be rotated by any angle necessary to clearly view the vascular anatomy and to make quantitative ultrasound caliper measurements of the stenotic lumen and normal vessel caliber.
Three-dimensional Doppler images accurately classified 53 of 61 vessels (87%) into categories of stenosis compared with angiography. All stenoses with >60% diameter reduction were detected and classified as such, for a sensitivity of 100%.
Three-dimensional vascular imaging based on amplitude (power) Doppler data provides an accurate noninvasive technique for quantitative diagnosis of carotid bifurcation atherosclerotic disease, with selectable viewing projections that eliminate vessel overlap and other artifacts, and complements the hemodynamic data already available with two-dimensional duplex ultrasound.
我们评估了利用振幅多普勒成像数据的三维重建来定量评估颈动脉分叉狭窄的疗效。
存储连续64帧振幅（功率）多普勒图像，重新组合成代表通畅管腔的三维图像。然后可以将这些图像旋转到所需的任何角度，以清晰地观察血管解剖结构，并对狭窄管腔和正常血管管径进行定量超声卡尺测量。
与血管造影相比，三维多普勒图像将61条血管中的53条（87%）准确分类为狭窄类别。所有直径减少>60%的狭窄均被检测到并如此分类，灵敏度为100%。
基于振幅（功率）多普勒数据的三维血管成像为颈动脉分叉动脉粥样硬化疾病的定量诊断提供了一种准确的非侵入性技术，具有可选择的观察投影，可消除血管重叠和其他伪像，并补充了二维双功超声已有的血流动力学数据。
