| 摘 要： | 目的 掌握上海市"十五"和"十一五"期间X射线CT医疗照射水平现状和应用频率的发展趋势。方法 采用面上普查的方式,调查上海市医用X射线CT机应用情况,并分头部、体部调查上海市各医院CT检查年人次数,并结合上海市历年人口资料计算X射线CT医疗照射应用频率。结果 截至2007年底上海市共有医用X射线CT应用单位101家,在用医用X射线CT机151台。上海市"十五"和"十一五"期间X射线CT医疗照射应用频率逐年递增,2007年CT检查年频率为128.16人次/千人口,其中头部检查年频率66.94人次/千人口,体部检查年频率61.22人次/千人口,CT检查年频率占各类X射线诊断检查年频率总数的12.8%。结论 上海市"十五"和"十一五"期间X射线CT应用单位数和设备数及医疗照射应用频率较"九五"期间有较大增幅,CT检查年频率占各类X射线诊断检查的比例大幅增加。频率水平的增长是导致公众集体剂量负担增加的主要原因。 |
