(上标 99m)Tc-ECD脑血流灌注显像评估学校恐怖症患儿脑血流差异

Objective To explore the clinical and epidemiological value of semi-quantitative regional cerebral blood flow (rCBF) imaging in children with school phobia. Methods A total of 20 cases diagnosed with school phobia were examined with rCBF. Twelve were males and the other 8 were females. The mean age was (14.2±2.1) years (11-18 years). Semi-quantitative analysis methods were used to investigate the correlations among gender, age and rCBF. Results There were significant differences in the rCBF of right fronto-parietal lobe, right occipital lobe, caput and putamen, left thalamus and hippocampus, and temporo-occipital lobe between males and females (P ＜0. 05). There was no relationship between purfusion index (P1) and age (P＞0.05). Only the P1 of left temporo-parietal lobe of those≥15 years old was significantly different from that of those ≥15 years old (P＜0.05). Conclusion (superscript 99m)Tc-ECD rCBF perfusion imaging plays a role in the study of epidemiology and treatment of school phobia.
