摘　　要：中枢神经系统(CNS)血管炎是一组主要累及CNS的炎性血管病变。数字减影血管造影(DSA)、CT血管成像(CTA)及MR血管成像(MRA)能够清楚显示管腔的形态变化,但对于管壁的显示存在缺陷。近年来,一些新的成像技术能够提供管壁信息并判断疾病的活动性,其中高分辨力血管壁成像(HR-VWI)能够直接显示病变的管壁特征,在血管炎的鉴别诊断及治疗随访方面发挥重要作用。回顾CNS血管炎的分类和诊断标准,并对各种影像技术在CNS血管炎的成像特征及应用予以综述。Central nervous system(CNS)vasculitis is a group of inflammatory vascular diseases which mainly involves in CNS.Digital subtraction angiography(DSA),CT angiography(CTA)and MR angiography(MRA)can clearly show the morphological changes of the lumen,but there are defects in the display of the vessel wall.In recent years,some new imaging techniques can also provide vessel wall information and identity the activity of disease,among them,high-resolution vessel wall imaging(HR-VWI)can directly demonstrate the wall characteristics of the lesion,it plays an important role in the differential diagnosis and follow-up of vasculitis.We reviewed the classification and diagnostic criteria of CNS vasculitis and introduced the features and applications of the imaging techniques.
