We performed magnetic resonance angiography (MRA) and susceptibility-weighted imaging (SWI) to observe cerebral changes during a migraine attack in a 28-year-old man. MRA revealed regional arterial spasm, and findings of SWI were consistent with decreased blood flow and/or venous dilatation. Because these noninvasive techniques can be performed repeatedly at short intervals, they can be useful for evaluating hemodynamic changes during and after migraine attacks.
我们对一名 28 岁男性偏头痛发作期间的脑部变化进行了磁共振血管造影（MRA）和磁敏感加权成像（SWI）检查。MRA 显示区域性动脉痉挛，SWI 的结果与血流减少和/或静脉扩张一致。由于这些非侵入性技术可以在短时间内重复进行，因此它们可用于评估偏头痛发作期间和之后的血液动力学变化。
