Cranial MR imaging was performed in three patients in whom herpes simplex encephalitis was subsequently proved. In all cases, the postcontrast T1 weighted MR images obtained with magnetization transfer saturation showed greater central nervous system involvement than was apparent on the conventional MR images. Specifically, the postcontrast magnetization transfer images were superior at delineating generalized meningeal enhancement as well as focal areas of brain involvement not seen on noncontrast T2-weighted images orconventionalpostcontrast T1-weightedimages.
对三名随后被证实患有单纯疱疹性脑炎的患者进行了头颅磁共振成像检查。在所有病例中，采用磁化传递饱和技术获得的增强后T1加权磁共振图像显示中枢神经系统受累程度比传统磁共振图像上明显更广泛。具体而言，增强后的磁化传递图像在显示弥漫性脑膜强化以及在非增强T2加权图像或传统增强后T1加权图像上未见的脑受累局灶性区域方面更具优势。
