HR-MRI在CNS血管炎诊断、疗效和预后评估价值的研究
发布时间:2021-11-25 21:30
目的:(1)探究中枢神经系统(CNS)血管炎HR-MRI影像特征;(2)探讨HR-MRI对CNS血管炎治疗疗效和预后评估的价值。方法:(1)选择2018年1月-2020年1月在我院影像科经3D-TOF MRA发现颅内动脉狭窄且病因不明确,或临床怀疑CNS血管炎的患者50例,行3.0T HR-MRI平扫及增强扫描。(2)记录最终诊断为CNS血管炎的24例患者的年龄、性别、实验室检查结果及HR-MRI影像表现,进行随访,综合临床及影像学特征评估患者的治疗反应并记录每次随访结果。结果:1.24例CNS血管炎患者平均年龄32.5岁,中位年龄32.5岁。其中男性16例(67.0%),平均年龄32.6岁(23-46岁)。女性8例(33.0%),平均年龄32.4岁(15-43岁)。2.24例CNS血管炎受累血管壁HR-MRI均表现为弥漫均匀性向心性增厚,5例(20.8%)累及单一动脉节段,19例(79.2%)累及多动脉节段,共计累及99个动脉节段。7个(7.1%)动脉节段1级强化,92个(92.9%)动脉节段2级强化。30个(30.3%)动脉节段轻度狭窄,43个(43.4%)动脉节段中度狭窄,21个...
