第一代数字减影磁共振血管造影术使用厚片对比增强二维投影技术已证实磁共振成像的潜力，以产生无创的亚秒级血管造影的颅颈循环。随着时间分辨技术变得更加复杂，并且可以获得具有高各向同性空间分辨率的3D采集，我们可能开始看到导管血管造影术作为诊断程序的消亡。
The first generation of digital subtraction MR angiography using thick-slab contrast-enhanced 2D projection techniques has confirmed the potential of MRI to produce noninvasive subsecond angiograms of the craniocervical circulation. As time-resolved techniques become more sophisticated and 3D acquisitions can be obtained with high isotropic spatial resolution we may start to see the demise of catheter angiography as a diagnostic procedure.
