 (submitted: July 14, 2016)
Recurrence [ Time Frame: three months to one year ]
The patients will be monitored whether they recured multiple sclerosis and neuromyelitis optica spectrum disorders confirmed by neurologist and conventional MRI. Clinical suspicious signs of recurrence : visual loss,urination and defecation function disturbance and so on. Conventional MRI: there are new lesions or the lesions show high signal on diffusion weighted images or enhancement on post contrast enhanced images.

Descriptive Information
Brief Title Multimodel Magnetic Resonance Imaging (MRI)of Multiple Sclerosis and Neuromyelitis Optica Spectrum Disorders
Official Title Multimodel MRI to Explore the Pathophysiology of Multiple Sclerosis and Neuromyelitis Optica Spectrum Disorders
Brief Summary

To investigate multimodel MRI exploring the pathophysiology of multiple sclerosis and neuromyelitis optica spectrum disorders.

The investigators use multimodel MRI to evaluate the extent of blood-brain barrier and white matter fiber tracts destruction , iron deposition and cerebral blood flow of associated regions in multiple sclerosis and neuromyelitis optica spectrum disorders using contrast-enhanced magnetic resonance imaging , quantitative susceptibility mapping, diffusion tension imaging, and arterial spin labeling with post labeling delay of 2.0 seconds. Transfer constant volume , magnetic susceptibility, cerebral blood flow and fractional anisotropy(FA) value were measured in lesion and normal appearing white matter.

Detailed Description

Patients:

Patients with multiple sclerosis and neuromyelitis optica spectrum disorders were included. clinical characteristics such as disease duration, expanded disability status scale(EDSS) score, age, associated laboratory examination(autoantibodies directed to aquaporin-4 and oligoclonal bands in serum as well as cerebrospinal fluid)were recorded.

Imaging scan were conducted at admission, six months and one year after admission

Imaging protocols:

MRI scan protocols: T2 weighted image, T1 weighted image, Diffusion weighted image(DWI), fluid-attenuated inversion recovery(FLAIR), dynamic contrast-enhanced magnetic resonance imaging(DCE-MRI) , diffusion tension imaging(DTI) ,quantitative susceptibility mapping(QSM) , arterial spin labeling(ASL) with post labeling delay(PLD) of seconds, sagittal CUBE Fluid Attenuation Inversion Recovery (FLAIR) images, sagittal 3-dimensional Fast Spoiled Gradient Echo(3D-FSPGR).

Contrast agent:

Omniscan 0.1mmol/kg, Inject rate:2ml/s

Imaging evaluation:

Transfer constant volume value measured by DCE-MRI indicates the extent of blood-brain barrier destruction.

Magnetic susceptibility manifests iron deposition in lesions and normal appearing white matter.

Diffusion tension imaging demonstrates the extent of white matter fiber tracts destruction.

Arterial spin labeling(ASL) with post labeling delay(PLD)of seconds shows cerebral blood flow in associated regions.
