Arterial spin labeling (ASL) is a magnetic resonance perfusion technique that allows for quantification of cerebral blood flow (CBF) without the use of contrast or radiation. Several applications of ASL have been described in diagnosis of strokes and stroke mimics, intracranial tumors, and other conditions. Various vascular anomalies exhibit specific CBF patterns that correlate with different signal intensities on ASL. In this case-based review, we demonstrate the utility of ASL in diagnosis and surveillance of vascular anomalies in the intracranial compartment.
动脉自旋标记(ASL)是一种磁共振灌注技术,可在不使用造影剂或辐射的情况下定量测量脑血流量(CBF)。ASL 在诊断中风和中风模拟、颅内肿瘤和其他疾病方面有多种应用。各种血管异常表现出与 ASL 上不同信号强度相关的特定 CBF 模式。在本案例综述中,我们展示了 ASL 在诊断和监测颅内血管异常方面的效用。
