某家医院儿童CT扫描剂量水平分析

Dose level of pediatric CT scanning in a hospital

目的分析某家医院2021年儿童CT扫描剂量水平并提出优化扫描建议。方法选取某市某家医院儿童CT扫描资料,分析不同年龄组、不同扫描部位的典型剂量值、典型扫描参数的差异。结果各年龄组中头颅平扫、上颌窦及胸部平扫样本量大于10,其中1岁组和5岁组头颅平扫、上颌窦两部位的kV、mA及CTDIvol值相同,胸部扫描的参数值差异较大。结论该医院扫描参数尚有优化空间,应持续采取最优化措施。

Objective To investigate the dose level of pediatric CT scan in one hospital,and to provide recommendations for optimized scanning.Methods The CT scan data of children were collected from this hospital to analyze the differences in typical dose values and typical scanning parameters between different age groups and different scanning parts.Results The sample size was>10 for routine cranial scan,routine maxillary sinus scan,and routine chest scan in each age group,and the 1-year-old group and the 5-year-old group had the same kV,mA,and CTDIvol values of routine cranial scan and maxillary sinus scan,but with relatively great differences in the parameters of chest scan.Conclusion Scanning parameters in this hospital can be further optimized,and optimization measures should be adopted continuously.
