摘　　要：目的:探讨胸部DR、X线断层融合照片(DCTS)和CT扫描3种检查方法对新型冠状病毒肺炎(简称新冠肺炎)的诊断价值。方法:回顾性分析37例新冠肺炎的胸部DR、DCTS和CT资料,对比3种影像检查方法对新冠肺炎肺内病变的显示能力。结果:对肺内磨玻璃样密度灶的显示,DR(27.0%,10/37)与DCTS(75.0%,21/28)比较,差异有统计学意义(P<0.05);DCTS与CT(88.9%,24/27)比较,差异无统计学意义(P>0.05)。结论:在新冠肺炎的显示方面,DR分辨力低,易漏诊;DCTS和CT的密度和空间分辨力明显高于DR,能提高对肺内病变细微结构的显示能力;DCTS与CT对新冠肺炎的诊断效能相近,均可作为新冠肺炎筛查的首选方法。Objective:To investigate the diagnostic value of three different examination methods of chest DR,digital chest tomosynthesis(DCTS)and CT scan on the diagnosis of COVID-19.Methods:A retrospective analysis of three examination methods of chest,DR,DCTS,and CT scans of COVID-19 patients diagnosed in our hospital from January 1 to February 29,2020.And we compared the three different imaging methods to COVID-19 display ability of pneumonia intrapulmonary lesions.Results:A total of 37 patients with COVID-19 were included.The DR group(10/37)and DCTS group(21/28)of 37 patients with COVID-19 showed significant differences in intrapulmonary ground-glass density lesions(P<0.05).DCTS group(21/28)and CT group(25/27)showed no statistically significant difference in intrapulmonary ground-glass density lesions(P>0.05).Conclusions:Comparison of the three imaging methods of COVID-19,the DR density and spatial resolution is low,which is easy to be false negative and miss lesions.DCTS density and spatial resolutions are higher than DR,which can improve the ability to display the fine structure of intrapulmonary lesions.Therefore,DCTS and CT are the best choices for the image diagnosis of COVID-19.
