摘要

目的:本研究的目的是量化每一种计算机断层扫描(CT)减剂量方案的减剂量。对象和方法:150例重复CT检查,每次检查采用CT剂量减少技术。根据剂量长度乘积计算与他们之前的标准CT检查相比剂量减少的百分比。结果:采用扫描参数优化技术检查95例,采用多相缩小扫描47例,采用限定扫描范围检查8例。扫描参数优化、多相扫描减少和扫描范围限制的剂量减少率分别为43.3%、52.5%和39.1%。在扫描参数优化中,通过降低管电压和降低管电流降低剂量的比例分别为47.9%和38.6%。结论:本文提出的降剂量方案简单可行,适用于大多数现代CT扫描仪。多相扫描还原显示最大剂量还原。所有这些技术都不依赖于CT扫描仪,但需要为个体患者量身定制的特殊CT方案,以优化患者CT剂量的最佳诊断质量。通讯:Limchareon S,泰国布拉法大学医学院放射学与核医学部,电话:+6638386554;传真:+ 6638386557;电子邮件:sornsupha@hotmail.com

Management of radiation dose reduction in computed tomography: an experience at burapha university hospital, thailand
Objective: The purpose of this study was to quantify the dose reduction for each computed tomography (CT) reduction dose protocol. Subject and Method: One hundred and fifty repeat CT examinations with an implementation of a CT dose reduction technique per examination were included. Percent of dose reductions compared with their prior CT examinations with standard CT protocols in terms of dose length product were calculated. Result: There were 95 examinations using scanning parameter optimization technique, 47 examinations using reduction of multiphase scanning and 8 examinations using limited scan range. Percent of dose reductions for scanning parameter optimization, reduction of multiphase scanning and limitation of scan range were 43.3%, 52.5%, and 39.1% respectively. Among the scanning parameter optimization, percent of dose reductions by lowering tube voltage, and lowering tube current were 47.9%, and 38.6%, respectively. Conclusion: The presented dose lowering protocols are simple and available in most modern CT scanners. Reduction of multiphase scanning shows highest dose reduction. All of these techniques do not depend on CT scanners but requiring special CT protocol tailored for the individual patient for optimal diagnostic quality in the optimization of patient dose in CT.
