摘　　要：目的 探讨高分辨率磁共振成像(HR-MRI)在鉴别中枢神经系统血管炎(CNSV)和可逆性脑血管收缩综合征(RCVS)的应用价值.方法 选择CNSV患者14例和RCVS患者6例,所有患者均行三维时间飞跃法磁共振血管成像(3D-TOF-MRA)和HR-MRI扫描.比较2组患者受累节段管壁的HR-MRI表现,包括管壁最大厚度,管壁增厚方式(偏心性或向心性),管壁强化程度,并进行统计学分析.计量资料采用t检验,计数资料采用χ^(2)检验.结果 CNSV组患者受累节段管壁最大厚度(1.81±0.45)mm,明显高于RCVS组(1.10±0.12)mm,差异有统计学意义(t=12.296,P<0.001);CNSV组患者管壁明显强化节段所占比例高于RCVS组,无强化节段所占比例低于RCVS组,差异有统计学意义(χ^(2)=34.252,P<0.001).结论 CNSV与RCVS的管壁表现存在明显的差异,HR-MRI可以用来鉴别诊断CNSV和RCVS.Objective To investigate the clinical application value of high-resolution magnetic resonance imaging(HR MRI)in the differential diagnoses of central nervous system vasculitis(CNSV)and reversible cerebral vasoconstriction syndrome(RCVS).Methods A study of imaging data of 14 patients with CNSV and 6 patients with RCVS were performed.HR-MRI and three-dimensional time-of-flight magnetic resonance angiography(3D-TOF-MRA)were performed in all patients.The HR:MRI manifestations of the involved seg-ments of the vascular wall in the two groups were compared,including the vascular wall max-thickness,the styles of the vascular wall thickening(eccentric or concentric),the enhanced-degree of the vascular wall,and the data were statistically analyzed.X2 test was used for counting data and t test was used for measuring data.Results The wall max thickness of CNSV group was larger than that in RCVS group[(1.81±0.45)mm vs(1.10±0.12)mm],there was a statistical significance(t=12.296,P<0.001).Compared with the RCVS group,the proportion of strong enhancement was higher in the CNSV group,while the proportion of non-enhancement was lower,and the differences were statistically significant(χ^(2)=34.252,P<0.001).Conclusion There is a significant difference in the wall performance between CNSV and RCVS,HR MRI can be used for the differential diagnosis between CNSV and RCVS.
