移床技术在盆部及下肢动脉增强MRA检查中的初步应用

目的　初步评估移床扫描技术 (MobiTrak)在盆部及下肢动脉MRA检查中的应用价值。方法　对 12例临床上疑有盆部和下肢动脉疾病的病人进行了三维动态增强MRA检查。其中 3例同时进行了动脉造影 ,4例做了手术探查。结果　 12例患者均满意地显示了感兴趣区血管。其中下肢动脉闭塞症 8例 ,人工血管移植术 2例 ,动脉瘤 2例。结论　移床扫描技术能准确地整体评价盆部和下肢动脉病变 ,是一种可靠的、有应用潜力的检查方法

CE-MRA of the Arteries of the Pelvis and legs with Automatic Table Movement

Objective To evaluate the clinical efficacy of MRA in the arteries of the pelvis and lower extremity with automatic table movement (MobiTrak).Methods 12 cases suspected of pelvis and lower extremity artery diseases underwent dynamic 3D contrast enhanced MRA and automatic table movement at the same time.Three cases underwent artery angiography,four cases were detected by operation.Results All diseased arteries were well demonstrated.Among them,lower extremity artery occlusion 8,failing vascular grafts 2,artery aneurysms 2.Conclusion Automatic table movement is of value in assessing pelvis and lower extremity artery diseases accurately.And it is a reliable and potential new technique.
