摘　　要：目的:探讨多块重叠薄层采集(MOTSA)全程脑动脉磁共振血管成像(MRA)技术的临床应用价值。方法:运用MOTSAMRA技术进行全程脑动脉成像,以期获得能够满足临床筛查、诊断需要的血管图像,同时就扫描细节进行探讨。回顾性分析48例采用MOTSAMRA技术全程脑动脉血管成像的病例资料,对图像的临床筛查、诊断满意度进行评价分析。结果:48例中有44例获得高质量的图像,占91.7%,4例图像质量较低,占8.3%。结论:MOTSA全程脑动脉磁共振血管成像技术能够获得满足临床筛查、诊断需要的图像。Objective：To explore the clinical application of multiple overlapping thin-slab acquisition （MOTSA） technique to acquire the whole cerebral artery images. The details of scanning methods are also discussed. Methods：Consecutive 48 cases with MOTSA scanning technique were retrospectively analyzed and the image quality was evaluated for the requirement of clinical screening and diagnosis. Results： The images from 44 cases were of high quality, that was 91. 7% of 48 cases, and images from 4 cases were of low quality, that was 8.3% of 48 cases. Conclusion：The whole cerebral artery images can be acquired with MOTSA technique and can be used for clinical screening and diagnosis.
