To assess the potential of magnetic resonance angiography (MRA) as an adjunct to spin-echo sequences in evaluating the cerebral vascular anomalies seen in Sturge-Weber syndrome.
Four pediatric patients with Sturge-Weber syndrome were evaluated with conventional MR imaging and with arterial and venous MRA. Resultant images were evaluated for evidence of volume loss, cortical enhancement, vascular anomalies, and enlarged choroid plexus.
Venous MRA revealed reduced flow of the transverse sinuses and jugular veins, prominent deep collateral venous system, and a lack of superficial cortical veins. Arterial MRA, performed in all cases, revealed a reduced flow signal from the left middle cerebral artery in one hemiparetic patient and angiomatous changes of high branches of a middle cerebral artery in two patients.
Arterial and, in particular, venous MRA can be useful adjuncts to standard spin-echo sequences in diagnosing Sturge-Weber syndrome.
评估磁共振血管造影（MRA）作为自旋回波序列的辅助手段，在评估斯特奇-韦伯综合征中所见脑血管异常方面的潜力。
对4例患有斯特奇-韦伯综合征的儿科患者进行了常规磁共振成像以及动脉和静脉MRA检查。对所得图像进行评估，以寻找体积缩小、皮质强化、血管异常和脉络丛增大的证据。
静脉MRA显示横窦和颈静脉血流减少、深部侧支静脉系统突出以及缺乏浅表皮质静脉。所有病例均进行了动脉MRA检查，结果显示1例偏瘫患者左侧大脑中动脉血流信号减少，2例患者大脑中动脉高分支出现血管瘤样改变。
动脉MRA，尤其是静脉MRA，在诊断斯特奇-韦伯综合征时可作为标准自旋回波序列的有用辅助手段。
