Magnetic resonance angiography (MRA) offers a noninvasive alternative for studying normal and pathological blood vessels within the brain. Insights from important clinical aspects of intracranial vascular disease enable the effective application of MRA. Several MRA techniques have demonstrated clinical utility for the detection and characterization of intracranial vascular pathology. Clinical protocols should comprise combinations of time-of-flight and phase-contrast acquisitions to achieve diagnostic sensitivity.
磁共振血管造影（MRA）为研究脑内正常和病变血管提供了一种非侵入性的替代方法。颅内血管疾病重要临床方面的见解有助于MRA的有效应用。几种MRA技术已证明在检测和表征颅内血管病变方面具有临床实用性。临床方案应包括时间飞跃法和相位对比采集的组合，以实现诊断敏感性。
