多站式三维动态增强磁共振下肢血管造影成像技术进展

摘要

With the development of magnctic resonance angiography (MRA) . multi-position three-dimensional dynamic conrrast-enhanced MRA (3D CE MRA) could provide high SNR and high resolution images of peripheral vessels. It plays an important role in the diagnosis and follow-up of the arterial diseases of lower extremities because of nonradiation, noninvasion and non-nephrotoxic. This article reviewed the advances of 3D CE MRA in peripheral vessels.%随着磁共振血管成像(MRA)技术不断发展成熟,多站式三维动态对比增强血管成像(3D CE MRA)应用于下肢动脉病变检查,可获得高信噪比及高分辩率的下肢血管图像,并具有无辐射、无创性、无肾毒性等优点,成为诊断下肢动脉疾病的重要检查方法,具有广阔临床前景.本文对下肢3D CE MRA的技术进展进行综述.
