Magnetic resonance imaging characteristics of neuromyelitis optica / 中国医学影像技术

ABSTRACT

Neuromyelitis optica (NMO) is an inflammatory-demyelinating disease of central nervous system that is characterized by severe attacks of optic neuritis (ON) and longitudinally extensive transverse myelitis (LETM).Conventional MRI is the most sensitive method in detection of NMO lesions in brain,spinal cord and optic nerve,which can objectively show the site,number,size and distribution of lesions.The MRI features of NMO lesion in brain,spinal cord and optic nerve lesions were reviewed in this article.
