摘　　要：目的通过本研究探讨64层螺旋CT低剂量扫描技术在胸部检查中的应用价值。方法选取2013年7月至2016年7月期间在本院行胸部64层螺旋CT检查的80例体检者作为研究对象,按照随机法将所有入选对象分为低剂量组与常规剂量组(各40例),低剂量组行低剂量64层螺旋CT扫描,常规剂量组行常规剂量64层螺旋CT扫描,比较两种剂量对胸部病变的诊出率。结果两组分别经低剂量和常规剂量64层螺旋CT扫描诊断后,低剂量组诊出率为92.00%,常规剂量组诊出率为92.50%,两组间诊出率比较差异无统计学意义(P>0.05)。低剂量组与常规剂量组扫描图像质量均为优级,两组支气管充气征、胸膜粘连征、毛刺征、分叶征、结节密度空泡征、不均匀及钙化均可清晰显示。结论 64层螺旋CT低剂量扫描与常规剂量扫描的诊出率无明显差异,较常规剂量相比,可减少对受检者的辐射危害,降低球管损耗,在临床中具有重要应用价值。Objective Through this research we aimed to explore the application value of 64 layers CT low-dose scanning technology in the chest check. Methods Totally 84 cases of people,who received chest examination by 64 layers CT for medical examination in our hospital during July 2014 and July 2016,were selected as the research objects,according to random number table method all selected objects were divided into low dose group,forty cases in each group. The people in low dose group received low dose 64 layers CT scan,those in routine dose group adopted regular doses of 64 layer CT scan,comparing the diagnosed rate of chest lesions of the two dose groups.Results The diagnosis rate of low dose group was 92.00%,and it was 92.50% of the conventional dose group,the difference between the two groups has no statistical significance（ P〉0. 05）.Image quality of both low dose group and conventional dose group are excellent,air- filled bronchi,pleural adhesion,spicule sign,sign of lobulation,nodular density cavity,uneven and calcification can clear display in both groups.Conclusions Diagnose rate of routine dose 64 spiral CT scans was equal to that of low dose 64 spiral CT scans. Compared to conventional treatment,low dose scan can reduce the radiation hazards,reduce the loss of the ball tube,has important application value in clinical.
