摘要
目的:探讨磁共振颈动脉成像扫描的技术方法及其影响图像质量的因素。方法:回顾性分析37例颈部动脉3D CE-MRA的病例资料,参照赵轶轲等的分级标准,分析图像质量。结果:采用自动跟踪技术获得的高质量图像占91.3%,延迟时间凭经验设定所获得的高质量图像占66.6%。结论:为了获得高质量的图像,扫描技术和方法的采用很关键,采用自动跟踪技术获及的图像质量较高。
Objective： MRA carotid artery imaging is a non-invasive imaging method. This paper discussed the scanning techniques in order to get high quality images. Methods=37 cases of carotid artery 3D CEMRA were retrospectively analyzed. The ratio of image quality was calculated in reference to Zhao＇s grading level. Results： The ratio of high quality images was 91.3% with the Smart Prep Scanning technology, while it was 66.6% with the technology of manually selected de laying time, Conclusion： Scanning techniques and methods are key to high quality images.
