多发性硬化(multiple sclerosis,MS)是一种常见的中枢神经系统脱髓鞘病变,在普通计算机断层扫描(computer tomography,CT)中阳性检出率很低,近年来临床上磁共振成像(magnetic resonanceimaging,MRI)已成为MS最有效的诊断方法。目前由于更多先进的MR成像技术的出现,MR对MS的早期发现、早期干预及辅助临床延缓和阻止MS从起初的炎性阶段发展至不可逆性变性阶段等方面具 Multiple sclerosis (MS) is a common central nervous system demyelinating disease. The positive detection rate in computer tomography (CT) is very low. In recent years, magnetic resonance imaging , MRI) has become the most effective diagnostic method for MS. At present, due to the emergence of more advanced MR imaging techniques, the early detection of MS, early intervention and clinical delay of MS and the prevention of the development of MS from the initial inflammatory stage to the irreversible stage of denaturation
