摘　　要：目的:探讨3.0T磁共振动态血管成像(TRICKS)的技术方法及临床应用价值。方法:采用3.0T高场强磁共振检查仪,对30例病人进行靶血管TRICKS检查。其中脑动脉5例,颈动脉7例,肺动脉2例,胸、腹主动脉5例,上肢动脉2例,股动脉9例。增强后与增强前的图像数据自动进行减影,得到血管图像,制作成动画。结果清晰地动态显示靶血管的解剖结构及病变情况。23例经数字减影血管造影(DSA)或手术证实。结论:合适的注药速率及注药量,合理选择扫描参数可以得到高质量的类似DSA的动态血管图像。Objective：To evaluate the methods and clinical value of dynamic MR angiography technique （TRICKS）in 3.0T MR. Methods：TRICKS were performed in 30 patients with 3.0T super conductive MR scanner, including 5 brain, 7 carotid arteries, 2 pulmonalis, 5 thoracic and abdominal aortas, 2 upper extremity arteries, 9 femoral arteries, The images of vasculosa were got by pre-and post-enhancement digit subtracted imaging, and made up cartoons. Results：The,normal anatomy and lesion site of arteries were showed movingly, Twenty-three cases were proved by DSA and/or surgery.Conclusion：High quality moving images that were similar to DSA depends on the optimizing injection rate and volume of contrast material,reasonable sequence parameters.
