Brain SPECT of regional cerebral blood flow using I-123 IMP demonstrated a focally decreased perfusion area immediately adjacent to a venous angioma in a patient with simple partial seizures. A positive correlation was obtained among the location of the venous angioma, the decreased perfusion area on SPECT images, and the electroencephalographic focus. Anomalous venous drainage through a venous angioma may explain a perfusion disturbance in the surrounding brain of the angioma. High-resolution SPECT imaging with magnetic resonance guidance provides useful information on the pathophysiology of venous angiomas.
使用I-123异丁基苄胍（IMP）进行的局部脑血流脑单光子发射计算机断层扫描（SPECT）显示，一名单纯部分性癫痫患者紧邻静脉血管瘤处有局部灌注减低区。静脉血管瘤的位置、SPECT图像上的灌注减低区以及脑电图病灶之间存在正相关。通过静脉血管瘤的异常静脉引流可能解释血管瘤周围脑区的灌注紊乱。磁共振引导下的高分辨率SPECT成像为静脉血管瘤的病理生理学提供了有用信息。
