Carotid atherosclerosis is an important contributor to ischemic stroke. When imaging carotid atherosclerosis, it is essential to describe both the degree of luminal stenosis and specific plaque characteristics because both are risk factors for cerebrovascular ischemia. Carotid atherosclerosis can be accurately assessed using multiple imaging techniques, including ultrasonography, computed tomography angiography, and magnetic resonance angiography. By understanding the underlying histopathology, the specific plaque characteristics on each of these imaging modalities can be appreciated. This article briefly describes some of the most commonly encountered plaque features, including plaque calcification, intraplaque hemorrhage, lipid-rich necrotic core, and plaque ulceration.
颈动脉粥样硬化是缺血性脑卒中的重要病因。在对颈动脉粥样硬化进行影像学检查时，描述管腔狭窄程度和特定斑块特征至关重要，因为两者都是脑血管缺血的危险因素。颈动脉粥样硬化可通过多种影像学技术（包括超声、CT 血管造影和磁共振血管造影）进行准确评估。通过了解其组织病理学基础，可以更好地理解这些影像学检查方法上的特定斑块特征。本文简要描述了一些最常见的斑块特征，包括斑块钙化、斑块内出血、富含脂质的坏死核心和斑块溃疡。
