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.
