颈动脉粥样硬化病变影像学检查方法的比较

颈动脉粥样硬化斑块的影像学检查不但有助于选择恰当的治疗方法,而且还可用于动脉粥样硬化发生和发展过程的研究。一种理想的检查方法除能提供管腔直径和狭窄程度等信息外,还应能准确反映斑块的构成成分和表面形态学特征。易损斑块的识别和分析是目前研究的热点。常用的检测方法包括超声、CT、MRI、CT血管造影、磁共振血管造影和数字减影血管造影等,后者是颈动脉病变影像学检查的金标准,但随着其他无创性影像学技术的发展,其地位日益受到挑战。

Comparison of Imaging for Identifying Carotid Atherosclerotic Lesions

The imaging of carotid atherosclerotic plaques is not only help choose the adequate method of treatment, but also can be used in the studies of the occurrence and development of atherosclerosis. Except for providing the information on lumen diameter and the severity of stenosis, an ideal examination should accurately reflect the constitutional composition of plaque and its surface morphological characteristics. The identification and analysis of the vulnerable plaque are the topics of general interests. The common methods of examination are CT, MRI, CT angiography, magnetic resonance angiography and digital subtraction angiography (DSA), and DSA is the imaging gold standard, however, with the development of other non-invasive imaging techniques, its status will be challenged increasingly.
