多发性硬化症 (MS) 中的脑萎缩通过脑磁共振成像 (MRI) 的脑体积变化百分比 (PBVC) 进行测量,已被确定为临床试验中的一个结果参数。目前尚不清楚不同脑组织区室内的体积变化对 PBVC 的影响有多大。我们分析了 600 名复发缓解型 MS 患者的成对 MRI 扫描(至少相隔 6 个月)。多元回归显示PBVC主要反映白质和皮质灰质体积损失,而深部灰质和白质病变较少体现。我们的研究结果有助于解释 MS 中 PBVC 的变化。
Brain atrophy in multiple sclerosis (MS), as measured by percentage brain volume change (PBVC) from brain magnetic resonance imaging (MRI), has been established as an outcome parameter in clinical trials. It is unknown to what extent volume changes within different brain tissue compartments contribute to PBVC. We analyzed pairs of MRI scans (at least 6 months apart) in 600 patients with relapsing–remitting MS. Multiple regression revealed that PBVC mainly reflects volume loss of white and cortical gray matter, while deep gray matter and white matter lesions were less represented. Our findings aid the interpretation of PBVC changes in MS.
