摘要
目的:探讨手动移床磁共振下肢血管成像技术及其临床应用价值。方法:应用3D小角度激发快速梯度回波序列(3D FLASH),对23例疑有下肢血管病变的患者,行磁共振下肢血管成像。使用Siemens Symphony 1.5T超导型磁共振扫描仪,使用头线圈及体表面线圈进行扫描,手动移床三段采集双下肢动脉血管图像,重组方法为MIP及MPR。结果:23例患者均获成功,其中16例经DSA证实,3D CE MRA图像直观、完整地显示腹、盆腔和下肢动脉结构和血管病变部位及范围。结论:手动移床磁共振下肢血管成像能较好的显示下肢动脉病变的范围和程度,快速、安全、有效,有利于血管疾病的检出,可以为临床提供更丰富的信息。
Objective：To evaluate the technique and application of three-dimensional contrast enhanced MR angiography（3D CE MRA） with manuel moving of table for arteriography of lower limb.Methods：3D CE MRA was performed in 23 cases suspected of having vessels disease by using three-dimensional fast low angle single shot sequence.Three-dimensional reconstruction techniques,including MIP and MPR,were adopted.Results：3D CE MRA was successfully performed on 23 cases,and 16 cases were confirmed by DSA.The position and extension of the lesions could be revealed on 3D-MRA images.Conclusion：3D CE MRA is a noninvasive and favorable method of depicting the lower limb arteries,which can provide more information for clinic.
