We performed 3T magnetic resonance angiography (MRA) during a spontaneous migraine attack. The patient was a 42-year-old woman migraineur diagnosed by the IHS criteria. The change of the middle meningial artery (MMA) was measured on the axial brain images using MATLAB for three phases (attack-free period, during an attack, a period after medication). There were no dramatic changes of vasodilation in the MMA during the attack (2.0 mm), attack-free period (diameter 1.9 mm), or period after medication (1.7 mm), resembling extrapolations of observations in experimental animal models. This finding suggests that the dramatic vasomotion might not be associated with migraine pathophysiology.
我们在一次自发性偏头痛发作期间进行了3T磁共振血管造影（MRA）。患者为一名42岁的偏头痛女性，根据国际头痛协会（IHS）标准确诊。使用MATLAB在轴向脑图像上测量脑膜中动脉（MMA）在三个阶段（无发作期、发作期间、用药后阶段）的变化。在发作期间（2.0毫米）、无发作期（直径1.9毫米）或用药后阶段（1.7毫米），MMA均未出现明显的血管扩张变化，这与实验动物模型中的观察推断相似。这一发现表明，显著的血管运动可能与偏头痛的病理生理学无关。
