颅内动脉狭窄的影像学诊断

The imaging diagnosis of intracranial artery stenosis

颅内动脉粥样硬化性狭窄是缺血性卒中的重要病因之一.采用影像学方法诊断颅内动脉狭窄并精确评价狭窄程度,对于指导临床治疗至关重要.文章综述了经颅多普勒、经颅彩色双功超声、血管内超声、血管内镜、磁共振血管造影、CT血管造影和数字减影血管造影在诊断颅内动脉狭窄方面的优缺点、研究进展和临床应用价值,为临床医生选择理想的检查工具提供参考.

Intracranial atherosclerotic stenosis is one of the important causes of ischemic stroke. It is of vital importance to guide clinical treatment using imaging methods to diagnose intracranial artery stenosis and accurately assess the degree of stenosis.This article reviews the advantages and shortcomings, advances and clinical application values of diagnosing intracranial artery stenosis using transcranial Doppler ultrasound, transcranial color-coded duplex sonography, intravascular ultrasound, magnetic resonance angiography, computed tomography angiography, and digital subtract angiography, which will provide references for clinicians to select ideal checking tools.
