摘要
目的:研究64排螺旋CT低剂量相对常规剂量在患者肺结节诊断的临床价值。方法:以2018年1月~2019年6月本院收入的肺结节患者78例作为研究对象,首先对所有患者进行常规剂量的CT扫描,而后再对患者实施低剂量扫描,时间间隔3d,对两次CT检查结果进行对比分析,采用的比较指标包括肺结节形状、大小及数量。结果:64排螺旋CT常规剂量与低剂量对患者进行肺结节检查,两种方法对于患者肺结节数量与大小、形态的诊断结果无明显差异,差异不具有统计学意义(P<0.05)。结论:64排螺旋CT低剂量扫描与常规剂量扫描对于患者肺结节的诊断效能接近,但低剂量对患者带来的损害相对常规剂量更小,临床价值相对更佳。
Objective:To study the clinical value of low-dose 64-slice spiral CT in the diagnosis of pulmonary nodules.Methods:In January 2018~June 2019 in our revenue of 78 patients with pulmonary nodules as the research object,first of all to regular doses of the CT scans of all of the patients,and for patients with low dose scanning,time interval,3d,this paper compares and analyzes the result of the two CT examination adopts comparative indicators including pulmonary nodule shape,size and quantity.Results:Routine 64-slice spiral CT and low-dose CT were used to detect pulmonary nodules in patients.There was no significant difference in the number,size and shape of pulmonary nodules between the two methods,and the difference was not statistically significant(P<0.05).Conclusion:Low-dose 64-slice spiral CT and conventional dose CT have similar diagnostic efficacy for patients with pulmonary nodules,but low-dose CT does less harm to patients than conventional dose and has better clinical value,so it is worthy of promotion and further exploration.
