| 目的 探讨MobiTrak三维对比增强MRA在下肢动脉成像中的应用价值。方法 对34例疑有下肢动脉疾病患者,应用MobiTrak技术,行下肢动脉3D CE-MRA扫描,经最大信号强度投影重建获得下肢整体血管图像,并结合原始图像进行综合分析(由两位有经验的专业医师采用双盲法评价)。结果 结果表明MobiTrak 3D CE-MRA大腿动脉图像质量较好,而小腿动脉图像显示稍差。诊断下肢动脉硬化闭塞症20例,其中17例经手术或DSA证实。结论 MobiTrak 3D CE-MRA对下肢动脉疾病患者提供了一种准确可靠、易行的检查手段。 |

| Objective To evaluate the application of MobiTrak three-dimensional-contrast-enhanced MR angiography(3D CE-MRA) in disease of the lower extremity arteries. Methods Thirty-four cases suspected of lower limbs vessel diseases underwent MobiTrak 3D CE-MRA and got whole vessels of lower limbs with maximum intensity projection(MIP). The MIP images and raw data in all of the patients were analyzed together(All of the cases were evaluated by two doctors in double-blind method). Results The result shows that MobiTrak 3D CE-MRA can get better images of thigh, but the lower leg not so better. Twenty cases with arteriosclerosis obliterans of the lower extremity were diagnosed by CE-MRA, seventeen cases were proved by surgical or the DSA. Conclusion MobiTrak 3D CE-MRA has high diagnostic accuracy in patients with lower extremity artery diseases. And it is reliable and easy technique. |
