摘　　要：目的探讨表观弥散系数(ADC)值与脑梗死分期的相关性。方法搜集150例经临床诊断并经MR证实的脑梗死病例,根据发病时间分为三组:急性期组(发病时间<2d);亚急性期组(发病时间2~14d);慢性期组(发病时间>14d)。采用磁共振弥散加权成像(DW I)测定各组病例ADC值。结果急性期组、亚急性期组和慢性期组ADC值分别为0.435±0.104、0.515±0.096和0.807±0.151,各组ADC值有显著性差异(P<0.05)。结论脑梗死各期ADC值与临床分期存在相关性,ADC值随梗死时间延长而增大。Objective To investigate the associativity between the apparent diffusion coefficient(ADC)and the stages of cerebral infarction.Methods All 150 cerebral infarction patients were confirmed by clinical diagnosis and magnetic resonance imaging.The patients were randomly divided into 3 groups according to the time course of infarct,the acute stage group(the time course < 2d),the subacute stage group(the time course from 2d to 14d) and the chronic stage group(the time course > 14d).The ADC values of patien...
