SclerosisImagingSequencesThe purpose of this study was to analyze the lesion brightness (image contrast) in multiple MRI sequences in patients with relapsing-remitting MS (RRMS), secondary progressive MS (SPMS), primary progressive MS (PPMS), and clinically isolated syndrome (CIS);and to correlate...
多发性硬化(multiple sclerosis,MS)是中枢神经系统常见的慢性炎性脱髓鞘疾病,以复发缓解型MS (relapsing-remitting MS,RRMS)最多见,是青年人非创伤性残疾的首要原因。传统观点认为MS是典型的白质局灶性脱髓鞘,即在常规T2加权成像(T2 weighted image,T2WI)...

Although magnetic resonance imaging (MRI) represents the most sensitive tool for the detection of white matter abnormalities in patients with multiple sclerosis (MS), the heterogeneity of MS placques severely hampers the elucidation of specific pathophysiological processes. In order to identify putative ...
