摘要
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显像对CCI早期诊断是一种敏感的技术，也有助于疗效观察及预后评估。
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.
