We applied regional perfusion imaging (RPI), a new arterial spin-labeling MR imaging method that selectively studies regions of the brain perfused by individual carotid and basilar arteries. In a patient with cerebrovascular disease, RPI showed cerebral tissue perfused by pial collateral vessels, thereby demonstrating the relationship between anatomic and functional information, which was lacking in conventional x-ray angiography. RPI may be useful to study functional collateral circulation and hence guide therapy in ischemic disease.
我们应用了区域灌注成像（RPI），这是一种新的动脉自旋标记磁共振成像方法，可选择性地研究由颈内动脉和基底动脉供血的脑区。在一名脑血管疾病患者中，RPI显示了软脑膜侧支血管供血的脑组织，从而揭示了解剖学信息与功能信息之间的关系，而这在传统X射线血管造影中是缺失的。RPI可能有助于研究功能性侧支循环，从而指导缺血性疾病的治疗。
