摘要
由于人体各解剖结构具有不同的天然高对比,故在保证必要诊断需求的前提下,应用低剂量扫描技术,以减少受检者的照射剂量、缩短检查时间以及减少设备消耗,是现代医技专业人员应该解决的问题和责任。在实践中发现人体很多部位进行相应的低剂量CT扫描,其病灶数量、定位、定性及诊断结果均与常规剂量扫描出现的基本相同,完全不影响解剖结构的显示及疾病的诊断,因此多层螺旋CT的低剂量扫描具有很重要的推广价值。
It is required for radiologists that less radiation dosage should be given to examinees with the shortened scan and less equipment consumption by using the low-dose scanning on the premise of satisfying the diagnostic needs because human anatomical structures vary in contrast ratio naturally.The clinical practice shows that the low-dose CT scan of multiple human sites is comparable to the conventional dose scan in the detection of lesions,localization,qualification,and diagnostic outcomes,which did not interfere with the manifestation of anatomical structures and the diagnosis of disease.Therefore,the low-dose multi-slice spiral CT scan is highly recommended.
