我们证明了血管选择性、非造影剂、时间分辨磁共振血管造影（MRA）技术的可行性，即“造影剂固有流入增强多相血管造影结合血管选择性动脉自旋标记技术（CINEMA-SELECT）"。该序列由两种主要技术组成：动脉区域的脉冲星星标记（PULSAR）和Look-Star采样。我们假设该技术允许选择性标记单个颅内动脉，由高分辨率四维数据组成，广泛覆盖大脑。在这项研究中，一种新的血管选择性，时间分辨血管造影技术证明，可以产生个人的血管造影无创标记的主要动脉血管近端的威利斯环。在健康志愿者中实现了清晰的血管描绘，并且三条血管的分离是明显的。该技术可在不使用造影剂的情况下对颅内动脉的结构和血流动力学进行评价。
We demonstrate the feasibility of the vessel-selective, non-contrast, time-resolved magnetic resonance angiography (MRA) technique, “contrast inherent inflow enhanced multi-phase angiography combining vessel-selective arterial spin labeling technique (CINEMA–SELECT)”. This sequence consists of two major techniques: pulsed star labeling of arterial regions (PULSAR) and Look–Locker sampling. We hypothesize that this technique allows selective labeling of single intracranial arteries, consisting of high-resolution four-dimensional data with a wide coverage of the brain. In this study, a new vessel-selective, time-resolved angiographic technique is demonstrated that can produce individual angiograms non-invasively by labeling the principal arterial vessels proximal to the circle of Willis. Clear vessel delineation is achieved, and the separation of the three vessels is evident in healthy volunteers. This technique could play an important role in the assessment of the structure and hemodynamics of intracranial arteries without the use of contrast agents.
