我们对11例脑血管病患者进行了磁共振数字减影血管造影（DSA）并行成像和锁孔数据采集的可行性评估。其中动脉主干狭窄/闭塞4例，动脉瘤3例，动静脉畸形2例，静脉血管瘤1例，静脉窦血栓1例。该技术不仅描述了解剖特征，MR血管造影（n=10/11），而且还描述了血流动力学，如侧支血流，时间分辨率为1.68 s/帧。与传统血管造影片（n=7）相比，4例患者的细节缺失（2例患者的动脉瘤颈显示不完整，2例患者的AVM成分分离不良）。虽然不如传统的血管造影，这种技术可以提供心血管疾病的解剖和血流动力学信息。
We assessed the feasibility of MR digital subtraction angiography (DSA) using parallel imaging and keyhole data sampling in the diagnosis of cerebrovascular diseases (CVDs) in 11 patients. Their diseases included arterial trunk stenosis/occlusion (n=4), aneurysm (n=3), arteriovenous malformation (n=2), venous angioma (n=1), and sinus thrombosis (n=1). The technique depicted not only anatomical features, comparably to MR angiography (n=10/11), but also hemodynamics such as collateral flow at a temporal resolution of 1.68 s/frame. When compared with conventional angiograms (n=7), details were missed in four patients (incomplete demonstration of aneurysmal neck in two and poor separation of AVM components in two). Although inferior to conventional angiography, this technique can provide both anatomical and hemodynamic information of CVDs.
