Study of dose optimization for X-ray in pediatric intussusception diagnosis and treatment

Objective: To explore dose optimization of pediatric intussusception reconstruction by digital pulse fluoroscopy and provide a feasible method to reduce radiation dose in fluoroscopy reconstruction. Methods: By reviewing related literatures and combining objective as well as principle of this study, perform air enema by using digital gastrointestinal machine with low pulse on intussusception children. Results: In experimental group with 60 cases, the accordant rate of diagnosis was 100%, and the reset success rate was 95%. In control group with 60 cases, the accordant rate of diagnosis 100% and reset success rate 93.3%. There was no significant difference between the two groups in the accordant rate of diagnosis and reset success rate, while in the time of radiation, experimental group was about 39.25% of the control group. Conclusion: Reducing pulse can not only meet the demand of clinical diagnosis and treatment, but also reduce radiation dose in children with intussusception. It is worthy of being applied to air enema reconstruction by digital pulse fluoroscopy. (authors)
