Correlation between volume and perfusion changes of deep gray matter nuclei and clinical score in patients with relapsing-remitting multiple sclerosis / 中国医学影像技术

ABSTRACT

Objective To investigate deep gray matter volume and perfusion changes in patients with relapsing-remitting multiple sclerosis (RRMS) with voxel-based morphometry (VBM) and 3D pseudo-continuous arterial spin labeling (3D pCASL), and to explore the relationship between the changed parameters of deep gray matter and expanded disability status scale (EDSS) and neuropsychological scale scores. Methods Totally 30 RRMS patients (RRMS group) and 24 healthy volunteers (control group) were enrolled and tested with EDSS scale and neuropsychological scale to evaluate memory function. All subjects underwent 3D T1WI and 3D pCASL, and the images were pretreated with SPM 8 and VBM 8 software on the Matlab platform. SPM statistical software was used to analyze the changes of deep gray matter volume and perfusion in RRMS patients, and further extraction of deep gray matter volume, perfusion parameter values in significantly changed brain regions, and correlation analysis was done for EDSS and neuropsychological scores. Results Compared with the control group, the volume of bilateral thalamus, left hippocampus, left putamen and right globus pallidus decreased significantly in RRMS group (all P0.05). Conclusion Volume and perfusion of deep gray matter are changed in RRMS patients, and the decrease volume and perfusion associate with impairment of memory function.
