目的二维超声（2D-US）是评价颈动脉粥样硬化的主要影像学技术。一种自动单扫描三维超声（3D-US）技术变得可用。与2D-US相比，我们评估了3D-US评估颈动脉斑块的可行性和准确性。颈动脉计算机断层扫描血管造影（CTA）用作参考。方法和结果126例脑卒中患者行颈动脉二维超声检查，73例同时行颈动脉三维超声和CTA检查。当有颈动脉斑块或2D-US显示狭窄面积≥ 20%时，进行3D-US检查。颈动脉的2D和3D-US图像均使用配备单扫描体积换能器的专用超声系统采集。共选择了73例患者的266条动脉，比较2D和3D-US之间颈动脉斑块的检出率。在73例患者中，颈动脉CTA检测到139个斑块。当使用颈动脉CTA作为参考标准时，3D-US显示出比2D-US更高的颈动脉斑块检出率（108个斑块（77.9%）vs. 70个斑块（50.4%））。应用3D-US和颈动脉CTA对73例患者的133条血管的颈动脉斑块体积（PV）进行了定量评价。3D-US和CTA之间的颈动脉斑块体积相当（148.5 +/- 133.0 mm（3）vs. 154.1 +/- 134.6 mm（3），P = 0.998，R：0.9825，P值<0.001）。结论3D-US单扫技术是一种检测动脉斑块和评估斑块体积的可行、准确的方法。
Aims Two-dimensional ultrasound (2D-US) is the mainstay imaging technique used to evaluate carotid atherosclerosis. An automated single sweep three-dimensional ultrasound (3D-US) technique became available. We evaluated the feasibility and accuracy of 3D-US in the assessment of carotid plaques compared to those of 2D-US. Carotid computed tomography angiography (CTA) was used as a reference. Methods and results Among 126 stroke patients who underwent carotid 2D-US, 73 underwent 3D-US and carotid CTA. 3D-US was pursued when there were carotid plaques or when area stenosis was >= 20% by 2D-US. Both 2D- and 3D-US images of the carotid arteries were acquired using a dedicated ultrasound system that was equipped with the single sweep volumetric transducer. In total, 266 arteries from 73 patients were selected for comparison of the detection rate of carotid plaques between 2D- and 3D-US. Among the 73 patients, carotid CTA detected 139 plaques. 3D-US demonstrated a higher detection rate of carotid plaques than did 2D-US (108 plaques (77.9%) vs. 70 plaques (50.4%)) when using carotid CTA as a reference standard. Carotid plaque volume (PV) of 133 vessels from 73 patients were quantitatively evaluated using both 3D-US and carotid CTA. Plaque volume of carotid artery was comparable between 3D-US and CTA (148.5 +/- 133.0 mm(3) vs. 154.1 +/- 134.6 mm(3), P = .998, R: 0.9825, P-value for r < .001). Conclusion 3D-US using a single sweep technique was a feasible and accurate method of detecting arterial plaques and assessing plaque volume.
