摘要
目的应用磁共振灌注技术来评估伴有视觉障碍的偏头痛患者脑枕叶皮质血流。方法 30例偏头痛患者及14例健康志愿者行动脉质子自旋标记磁共振灌注成像检查,采用FAIR技术获得受试者枕叶血流rCBF图,并由两名高年资放射科医生对图像进行分类,分为灌注不足、正常灌注和过度灌注三类。结果具有视觉先兆的偏头痛患者中枕叶区域灌注表现异常的有9例:6例为低灌注、3例为高灌注;无先兆但伴有视觉障碍临床症状患者中2例为低灌注;无先兆无视觉障碍患者中2例为高灌注。结论伴有视觉障碍的偏头痛患者存在脑枕叶皮质血流量异常,有先兆的偏头痛患者多表现低灌注。
Objective Using perfusion weighted imaging to study blood perfusion in occipital cortex of migraine with visual disorder Methods 30 migraine and 14 matched healthy control subjects took magnetic resonance perfusion weighted imaging examination. Flow-sensitive alternating invasion recovery mode was applied to get regional cerebral blood flow map. Perfusion of occipital cortex of brain was divided into hypo-, hyper- and normal perfusion by two radiologists. Results In migraine with aura, 9 abnormal subjects including 6 hypoperfusion and 3 hyperperfusion were found in occipital cortex. Two abnormal perfiasion were observed in non-threatened migraine and with visual disorder, which showed hypoperfusion in migraine with visual disorder and hyperperfusion in migraine threatened. Conclusion There was abnormal perfusion in occipital cortex in migraine with visual disorder, Hypoperfusion was mostly found in threatened migraine.
