MRI examination of 41 patients with clinical definite multiple sclerosis showed white matter lesions of high proton T2 signal consistent with demyelination in 76% and CSF abnormalities present in 76%. Of patients with CSF abnormalities, 26% had normal MRI scans; conversely 26% of patients with MRI abnormalities had negative CSF studies. Thus a significant number of multiple sclerosis patients had negative results on either MRI or CSF examination, while only 5% had normal results on both tests.
对41例临床确诊的多发性硬化症患者进行的MRI检查显示,76%的患者存在与脱髓鞘相符的高质子T2信号白质病变,76%的患者存在脑脊液异常。在脑脊液异常的患者中,26%的患者MRI扫描正常;相反,在MRI异常的患者中,26%的患者脑脊液检查结果为阴性。因此,相当数量的多发性硬化症患者在MRI或脑脊液检查中结果为阴性,而只有5%的患者两项检查结果均正常。
