    摘要:

    目的:探讨三维时间飞跃法MR血管成像(3D TOF MRA)和三维增强MR血管成像(3D CE-MRA)对脑血管病的诊断价值。方法:3D TOF MRA检查150例;其中9例进行3D CE-MRA检查,对比剂Gd-DTPA,0.2 mmol/kg,采集的源图像进行三维重建。常规MRI包括横断面T1WI、T2WI,矢状面T1WI。结果: 颅内血管显示正常56例,颅内动脉狭窄或闭塞46例、动脉瘤22例,动静脉畸形(AVM)21例,颈内动脉海绵窦瘘(TCCF)3例,烟雾病2例。结论:3D TOF MRA和3D CE-MRA能无创、快速、有效、准确地诊断脑血管病,可作为脑血管病的筛选和首选诊断方法。

    Abstract:

    Objective:To evaluate the value of three-dimensional time of flight MR angiography(3D TOF MRA) and three-dimensional dynamic contrast-enhanced MR angiography(3D CE-MRA) in the diagnosis of cerebrovascular diseases. Methods:Total of 150 cases underwent 3D TOF MRA, and 9 cases underwent 3D CE-MRA. Gd-DTPA(0.2 mmol/kg) was chosen as comparing agent. The source images were subtracted and recontructed. Normol scanning included transverse T1WI and T2WI, sagittal T1WI. Results:In 150 cases, 56 were normal, and 46 presented with ateriosclerosis and vaso-occlusive, 22 with aneurysms, 21 with AVM, 3 with trauma carotid-cavemuou fistula(TCCF), 2 with moyamoya. Conclusion:3D TOF MRA and 3D CE MRA are fast, non-invasive and effective techniques, and can accurately diagnose cerebrovascular diseases. They can provide overall information for treatment planning and can be used as the first choice for the diagnosis of cerebrovascular diseases.
