内囊后肢梗死后中央后回皮质下的FA值与体感诱发电位的关系
Fractional anisotropy and somatosensory evoked potentials in the postcentral gyrus subcortex after acute infarction of the posterior limb of the internal capsule
摘要
Abstract
Objective To investigate the relationship between fractional anisotropy (FA) and somatosensory evoked potentials (SEP) in the postcentral gyrus subcortex in patients with acute infarction of the posterior limb of the internal capsule. Methods Thirty-one patients with acute infarction of the posterior limb of the internal capsule underwent diffusion tensor imaging to obtain the FA values of the subcortical region of the postcentral gyms with manual placement of the regions of interest (ROE). SEP and the sensory functions of the patients were examined and graded. Results In each SEP grade group, the FA values of the subcortical region of the postcentral gyms were significantly decreased on the diseased side compared to those of the normal side (P<0.05). The FA values of the diseased side differed significantly between patients with different SEP grades (P<0.05), and increased SEP abnormalities were associated with lowered FA values. The sensory function of the patients was positively correlated to the grade of SEP (r=0.520, P<0.05). Conclusion For patients with acute infarction of the posterior limb of the internal capsule, the changes of FA in the postcentral gyrus subcortex on the diseased side are correlated and complementary to SEP in evaluating the prognosis.关键词
