| 摘要: |
| 颈动脉易损斑块是缺血性脑卒中发病机制中的一个重要部分，因此易损斑块的识别对卒中病人的诊断、治疗和预后有重要的临床意义。目前的影像方法对这种斑块的诊断仍存在一定挑战。随着超声成像及相关技术的进步，超声不仅可以筛查颈动脉狭窄和斑块的基本特征，还可以早期提示斑块的易损性。本文将从斑块构成，纤维帽厚度，新生血管和斑块形态四个方面来回顾超声对易损斑块评估的应用与进展。 |

| Abstract: |
| The presence of carotid vulnerable plaque plays an important role in the pathogenesis of ischemic stroke, therefore, the identification of vulnerable plaques is of important clinical significance in the diagnosis, treatment and prognosis in patients with stroke. Current imaging methods still present some challenges for the diagnosis of such plaques. With the development of ultrasound imaging and related technologies, ultrasound can not only screen the basic features of carotid artery stenosis and plaque, but also provide early indication on plaque vulnerability. This manuscript will review the application and progress of ultrasonic evaluation of vulnerable plaques from four aspects：plaque composition, fiber cap thickness, neovascularization and plaque morphology. |
