摘　　要：目的探讨胸部数字断层融合成像(digital tomosynthesis,DTS)对新型冠状病毒肺炎的诊断价值。方法收集32例我院确诊新冠肺炎患者影像检查资料(包括常规DR和DTS),对图像进行主观评价,比较两种方法获得的图像质量及其对肺内渗出性病灶检出能力。结果DR组优片率为31.2%,DTS组优片率为84.3%,DTS图像质量评分高于常规DR检查。DR阳性7例,检出病灶16处;DTS阳性17例,检出病灶38处。两组图像质量评分及检出肺内病灶能力差异有显著统计学意义(P<0.05)。结论断层融合成像检查能有效检出肺内病灶,提高普通放射学对新冠肺炎的诊断能力,在筛检、复查方面替代常规DR检查。Objective To explore the value of chest digital tomosynthesis(DTS)in the diagnosis of novel coronavirus pneumonia.Methods From Jan 2020 to Feb 2020,32 patients with the diagnosis of novel coronavirus pneumonia were recruited and the radiological materials,including DR and DTS,were compared with subjective evaluation and the ability demonstrating exudative inflammation lesions.Results The satisfactory rate of DR group 31.2%,DTS group was 84.3%.The image quality score of DTS was higher than that Of DR.In 7 patients with DR-positive and 17 patients with DTS-positive,16 lesions and 38 lesions were observed respectively,can precisely demonstrate the size and number,Compared with DR,DTS showed the lesions more clearly.Both of them were significantly different(P<0.05).Conclusion DTS can effectively observe the lung lesions,which improve the diagnostic capacity of general radiology for novel coronavirus pneumonia.DTS would be well suited as a low-dose screening and reexamination technique substitute for DR.
