磁共振血管成像评估颈动脉狭窄的研究进展

颈动脉狭窄是导致缺血性脑卒中的重要原因,早发现和早治疗可显著降低其致死率和致残率。磁共振血管成像以无创、无辐射、软组织分辨率高等特点而在颈动脉狭窄评估方面具有重要意义。作者就时间飞跃法磁共振血管成像(time of flight magnetic resonance angiography,TOF-MRA)、对比增强磁共振血管成像(contrast enhanced MRA,CE-MRA)、四维相位对比磁共振血管成像(four dimensional flow magnetic resonance angiography,4D-Flow-MRA)、零回波时间动脉自旋标记血管成像(zero echo time arterial spin labeling magnetic resonance angiography,zTE-ASL-MRA)、黑血成像技术(black blood,BB)和磁共振同时非增强血管成像和斑块内出血成像(simultaneous noncontrast angiography and intraplaque hemorrhage imaging,SNAP)等磁共振血管成像技术以及磁共振快速成像技术在评估颈动脉狭窄的应用及研究进展予以综述。

Research advances of magnetic resonance angiography in evaluating carotid arterystenosis

Carotid stenosis is an important cause of ischemic stroke.Early detection and early treatment can significantly reduce the fatality and disability rates.Magnetic resonance angiography plays an irreplaceable role in the quantitative assessment of carotid artery stenosis because of its advantages such as non-invasive,non-radiation and better resolution of soft tissue.This paper reviews the latest technology applications and research advances in the quantitative assessment of carotid artery stenosis using magnetic resonance angiography such as time of flight magnetic resonance angiography(TOF-MRA),contrast enhanced MRA(CE-MRA),zero echo time arterial spin aabeling MRA(zTE-ASL-MRA),four dimensional flow MRA(4 D-Flow-MRA),black blood(BB),simultaneous noncontrast angiography and intraplaque hemorrhage imaging(SNAP),and rapid magnetic resonance imaging.
