Abstract
Objective The purposes of this study were to analyze clinical characteristic and its signs on images of magnetic resonance imaging and MRI diagnosis values of Multiple Sclerosis in Spinal Cord.MethodsThere were 25 cases patients with spinal cord multiple sclerosis.The diagnosis of all patients had confirmed by clinical treatment and MRI diagnosis.In these patients,the male were 8 cases and the female were 17 cases.The age of these patients ranged from 21 to 64 years old,mean 32 years old.All patients had checked by MRI.Results The main clinical manifestations of spinal cord multiple sclerosis were limbs anesthesia,powerless and bad action,cervical part odynia,cacesthesia,cranial nerve lesion,ataxia,urine and sedes functional disturbance and so on.The lesion mainly developed in cervical cord.Cervical spinal cord was involved in 13 cases;cervical and thoracic spinal cord simultaneously in 9 cases;thoracic spinal cord in 2 cases and whole spinal cord in 1 case.On MRI,spinal MS showed some characteristics,The length of the lesion usually covered shorter than four vertebra bodies,The length was longer than the width.The diseasod cord was swollen in acute stage.The lesions were manifested as patches in shape and long ribbon shape with low or iso-signal intensity on TlWI and high-signal intensity on T2WI.The lesions usually located lateral or posterior surface in the axial image,and it was smaller than half axial area.The lesions in active stage were enhanced by Gd-DTPA,showing patchy or lamella-shape enhancement.The enhanced regions smaller than which were high-signal intensity on T2WI,The lesions anastated after had been treated with excitatory autacoid,The enhancement was lower or without enhancement on enhanced MRI scan.Conclusion MS of spinal cord has characteristic features on MRI and MR is the most important and sensitive method for diagnosing spinal cord MS.It is import to diagnose,treat and follow-up visit for MRI,multi-azimuths and multisequencing imaging.
