摘要:
近几十年来,CT成为诊断疾病的重要影像学手段之一。但是,考虑到患儿的高辐射敏感性,行CT时应当慎重。可以通过对剂量指数、剂量长度乘积、扫描层厚和面积这些CT相关参数的控制来降低患儿受照剂量。在保证CT图像清楚的前提下,对管电流、管电压、螺距的控制,同样可降低患儿受照剂量。通过有效剂量和集体剂量评估患儿的受照剂量。应当在辐射防护三原则的基础上开展患儿CT检查工作。
Abstract:
During the last decades,CT has become the predominant imaging technique in the diagnosis of diseases.However,given the high radiation sensitivity in children,CT scanning should be indicated extremely carefully.These CT related parameters such as CT dose index,dose-leugth product,layers and areas can be controlled to decrease pediatric patients exposure doses.To ensure the quality of CT images clear,tube current,tube voltage and pitch can also be controlled to decrease exposure doses.Children exposure doses could be evaluated through the measurement of the effective dose and collective does.Using CT in children patients should be on the basis of the radiation protection of the three principles.
