一种将正电子发射断层扫描与磁共振（MR）成像相关联的方法使作者能够在颈内动脉闭塞患者的t2加权图像中检查高强度白质区域。与同侧和对侧正常强度白质区相比，高强度区显示脑血容量增加。这一观察结果可能有助于解释MR图像中出现的一些斑片状白质病变。
A method for correlating positron emission tomography with magnetic resonance (MR) imaging enabled the authors to examine the high intensity white matter areas in T2-weighted images in patients with internal carotid artery occlusion. The high intensity areas showed increased cerebral blood volume compared with the ipsilateral and contralateral normal intensity white matter. This observation may have relevance in explaining some of the patchy white matter lesions seen in MR images.
