摘要 目的应用磁共振张量成像(DTI)研究急性后循环脑梗塞中FA值的变化规律,为临床提供诊断依据。方法选择发病3 d内的急性后循环梗塞患者68例,根据发病时间分为超急性期组(<6 h)及急性期组(6 h^3 d),分别测量不同时期梗死区和健侧区的FAAV值,使用配对t检验分析不同时期梗死侧与梗死对侧有无差异。结果超急性期19例PCCI患者梗死区FA值梗死区FA值平均值(0.439±0.105),梗死对侧FA值平均值(0.339±0.098),两侧比较有统计学差异(t=9.478,P<0.001);急性期组患者共49例,梗死区FA值平均值(0.275±0.14),梗死对侧FA值平均值(0.467±0.145),两侧比较有统计学差异(t=11.254,P<0.001)。结论定量分析DTI的FA值可以协助早期诊断脑梗死,并帮助精确临床分期。
