摘　　要：目的比较婴儿肝胆动态显像早期各时相肠道放射性分布检出率,探索保证诊断质量前提下优化早期检查方案可行性。方法回顾性分析2014年1月至2018年10月于郑州大学第一附属医院核医学科按常规检查流程行肝胆动态显像检查的婴儿297例,男,159例,女,138例,年龄最小3d,最大293d,平均(65.9±20.5)d。把受检者分为排泄正常和排泄异常两组,分别统计5、10、20、30、45、60min早期相各采集时间点肠道放射性分布的检出率,并按顺序递次配对2检验,比较其差异。结果297例受检婴儿,排泄正常者89例,排泄异常者208例。排泄正常组早期各时相肠道放射性分布的检出率,5、10、20min分别为5.62%、10.11%、19.10%,均较低;30、45、60min分别为71.91%、86.52%、100.00%,检出率明显增高;5min和10min,10min和20min,30min和45min,45min和60min肠道放射性分布的检出率比较,差异均无统计学意义(P>0.01),但20min和30min的检出率比较,差异有统计学意义(2=38.080,P<0.001)。排泄异常组早期各时相肠道均无放射性分布。结论优化婴儿肝胆动态显像常规检查流程,方案具有可行性,优化为30min和60min两次检查对诊断结果影响不大。Objective To compare the detection rates of intestinal radioactive distribution at the different phases of infants' hepatobiliary dynamic imaging and explore the feasibility of optimizing the early-stage inspection scheme on the premise of guaranteeing the diagnostic quality.Methods The data of 297 infants undergoing hepatobiliary dynamic imaging from January of 2014 to October of 2018 in The First Affiliated Hospital of Zhengzhou University were analyzed retrospectively.There were 159 male cases and 138 female cases.The minimum age was 3d, the maximum age was 293d, and the average age was (65.9±20.5)d.Those infants were divided into the normal excretion group and abnormal excretion group.The detection rates of intestinal radioactive distribution at the collection time points of 5, 10, 20, 30, 45 and 60 minutes at the early stage were counted respectively.The differences were compared by recursion paired 2 test.Results There were 89 cases with normal excretion and 208 cases with abnormal excretion among the 297 infants.In the normal excretion group, the detection rates of intestinal radioactive distribution at the collection time points of 5, 10 and 20 minutes were 5.62%, 10.11% and 19.10% respectively and they were relatively low, while those at the collection time points of 30, 45 and 60 minutes were 71.91%, 86.52% and 100.00% respectively and they were significantly increased.There were no significant differences between the detection rates at the collection time points of 5 and 10 minutes, 10 and 20 minutes, 30 and 45 minutes, and 45 and 60 minutes, respectively ( P >0.01), while the detection rates at the collection time points of 20 and 30 minutes were significantly different ( 2 =38.080, P <0.001).There was no radioactive distribution in the intestinal tracts of the abnormal excretion group at the different phases of the early stage.Conclusion It is feasible to optimize the routine examination procedure of dynamic hepatobiliary imaging in infants and the diagnosis is not affected by making the examination
