颈动脉粥样硬化斑块CTA及MRI诊断的研究进展

Research Progress of Carotid Atherosclerotic Plaque CTA and MRI Diagnosis

颈动脉粥样硬化斑块(CP)脱落是诱发缺血性脑卒中的重要危险因素,因此能够早期准确地评价斑块是否稳定并及时对其进行临床干预,在预防脑血管疾病的发生、发展方面具有重要意义。目前,对PC的研究主要集中于斑块的易损成分及类型。超声诊断、CT血管成像(CTA)、磁共振成像(MRI)、数字减影血管造影(DSA)及核医学等影像学手段均能够诊断CP,而CTA及MRI对CP诊断研究最具有临床意义及应用价值。现就CTA及MRI对颈动脉粥样硬化斑块的研究进展作一综述。

The loss of carotid atherosclerotic plaques(CP)is an important risk factor for ischemic stroke.Therefore,it is of great significance to accurately evaluate the stability of plaques and timely clinical intervention to prevent the occurrence and development of cerebrovascular.At present,the research on CP mainly focuses on the components and types of plaques.Ultrasound diagnosis,CT angiography(CTA),magnetic resonance imaging(MRI),digital subtraction angiography(DSA),and nuclear medicine can all diagnose CP.CTA and MRI have the most clinical significance and application value in CP diagnosis.The progress of CTA and MRI on carotid atherosclerotic plaques is reviewed.
