摘　　要：目的探讨CAREDose4D和SAFIRE技术下肺部孤立性磨玻璃结节(GGN)的诊断价值。方法选取2014年1月~2017年3月我院收治的肺GGN患者50例作为研究对象。入组患者均采用HRCT诊断,研究组采用CAREDose4D和SAFIRE技术进行扫描,对照组行常规方法扫描,部分数据是同一患者短时间间隔(小于30天)复查(采用两种不同扫描方式),以手术病理作为金标准,比较不同扫描方法的诊断效果。结果常规扫描纵隔窗图像质量、肺窗图像质量与CAREDose4D和SAFIRE图像比较差异无统计学意义(P>0.05);常规扫描与CAREDose4D和SAFIRE图像扫描长度比较差异无统计学意义(P>0.05),CAREDose4D和SAFIRE图像扫描CTDIvol、DLP以及ED等指标,低于常规扫描(P<0.05);CAREDose4D和SAFIRE图像的支气管狭窄或截断以及空泡或蜂窝检出率,略高于常规扫描(P<0.05),CAREDose4D和SAFIRE图像与常规扫描分叶、毛刺或尖角、血管集束、胸膜凹陷征检出率比较差异无统计学意义(P>0.05)。结论肺孤立性磨玻璃结节CT检查时,联合应用CAREDose4D和SAFIRE技术图像清晰,辐射剂量较少,值得推广应用。Objective To investigate the value of CAREDose4D and SAFIRE in the diagnosis of solitary pulmonary nodule（ GGN）. Methods 50 patients with pulmonary GGN admitted to the Yuyao people＇s Hospital of Zhejiang province in January2014-March 2017 were selected as the subjects. Patients with HRCT diagnosis,in the study group,were treated with CAREDose4D and SAFIRE technology scan,the control group underwent conventional scanning method,part of the data was the same with short time interval（ less than 30 days by using two different scanning methods）. Using surgical pathology as the gold standard,the diagnosis effect different scanning method was compared. Results Conventional scanning mediastinal window image quality,and lung window image quality; CAREDose4D and SAFIRE images showed no significant difference（ P〉0. 05）; There was no statistical significance of conventional scanning with CAREDose4D and SAFIRE image scanning length difference（ P〉0. 0 5）,CAREDose 4D,and SAFIRE scan image of CTDIvol,DLP and ED index were lower than that of conventional scanning（ P〈0. 05）; the detection rate of CAREDose4D and SAFIRE images of bronchial stenosis or truncation and vacuoles or honeycomb was slightly higher than the conventional scanning（ P〈0. 05）,CAREDose4D and SAFIRE images with conventional scanning of leaf,burrs or sharp,vascular bundle and pleural indentation rate had no significant difference（ P〉0. 05）. Conclusion The images obtained by CAREDose4D and SAFIRE technique in the diagnosis of solitary pulmonary nodule（ GGN） of the lung are clear and the radiation dose is small,so it is worthy of popularization and application.
