摘要/Abstract

摘要： 目的：探讨3T超高强磁场磁共振团注法三维动态增强MRA（3D DCEMRA）在腹部、盆腔及下肢血管成像中的应用。方法：使用GE EXCITE Ⅱ3.0T双梯度超导磁共振，采用体线圈、移床技术、高压注射器团注对比剂，对30例腹部至下肢血管受检者行3D DCEMRA检查，对所有受检者的原始图像在工作站利用ADW4.2软件进行MIP和REFORMAT重建并进行成像质量的评价。结果：30例受检者的腹部至下肢血管成像均获得满意效果，血管清晰，病变明确，其中12例闭塞性动脉硬化患者经手术证实与3D DCEMRA显示的血管病变相符。结论：3D DCEMRA是一种新的、有效的腹部至下肢血管成像方法。

Abstract: To evaluate the three dimensional dynamic contrast enhanced MRA (3D DCEMRA) in demonstrating abdomen to lower extremity arteries with 3.0T MR. Methods： A total of 30 patients were detected by 3D DCEMRA with body coil and movebed technique using 3.0T MR of GE company, and they were injected gadolinium contrast medium through intravenous bolus with the Spectris MR injector of MEDRAD. All the primary graphs were analyzed the MIP and REFORMAT reconstruction by ADW4.2 software. Results： All the 3D DCEMRA angiographies were clearly demonstrated, of them, 12 patients were found with arteriosclerosis obliterans, and the result was consistent with that of the operation. Conclusion： 3D DCEMRA is a new and efficient method in abdomen to lower extremity arteries imaging.
