Abstract:
Objective To explore the MRI features of brain and spinal cord in patients with multiple sclerosis(MS).Methods The data of MRI of 110 patients with clinic definite MS were analyzed retrospectively.Results The lesions on brain MRI were usually seen in the white matter surround the ventricle(55.8%),deep frontal lobe white matter(54.7%),deep parietal lobe white matter(44.2%)and brainstem(25.6%).Basal ganglia(23.3%)and thalamus opticus(11.6%)were also affected.The size of the brain lesions was varied,the appearances were punctiform,mottling,patching,ellipse and so on.The lesions of the spinal cord were usually on the cervical cord(75.0%)and thoracic cord(68.8%).There were string lesions which parallel spinal cord long axial and mottled lesions.The spinal cord lesions existed in both white matter and gray matter.10.0% of the patients had spinal cord atrophy or spinal cord swelling.The signal intensity of lesions was equal T1,long T2 or long T1,long T2,which was related with the clinical course.Conclusion Different size and appearance lesions in the white matter of brain and spinal cord are the main MRI features of MS.
