SPECT显像对小儿脑梗塞的研究

为了探讨ＳＰＥＣＴ对小儿脑梗塞（ＣＣＩ）的诊断价值，对２６例患儿采用ＳＰＥＣＴ局部脑血流灌注（ｒＣＰ）显像与ＣＴ对比研究，结果表明，脑梗塞灶及远隔区域的ｒＣＰ减少，ＳＰＥＣＴ和ＣＴ的阳性率分别为９２．３％（２４／２６）和８４．５％（２２／２６），两者无显著性差异（Ｐ〉０．０５），而发病２天以内９例的ＳＰＥＣＴ阳性率１００％（９／９）显著高于ＣＴ５５．６％（５／９）（Ｐ〈０．０５），提示ＳＰＥＣＴ显

Study on SPECT image for children with cerebral infarction

To explore the diagnostic value of SPECT image for children with cerebral infarction (CCI), comparative research was made on 26 cases undergoing regional cerebral perfusion (rCP) image between SPECT imaging and CT scanning. The results showed that the rCP in the infarct and its distant area was decreased. The positive rate of SPECT and CT were 92.3% (24/26) and 84.5% (22/26) respectively. The difference was not significant (P=0.67, P>0.05). But, the positive rate of SPECT image 2 days after onset in 9 CCI was 100% (9/9), significantly higher than 55.6% (5/9) in CT sacnning (P=0.04, P<0.05). These findings suggested that the SPECT imaging is a sensitive method for the early diagnosis of CCI, and also helpful for observation of the therapeutic effect and evaluation of the prognosis.
