This article is a Preprint
Preprints are preliminary research reports that have not been certified by peer review. They should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.
Preprints posted online allow authors to receive rapid feedback and the entire scientific community can appraise the work for themselves and respond appropriately. Those comments are posted alongside the preprints for anyone to read them and serve as a post publication assessment.

ABSTRACT
Background:
To investigate the diagnostic value of three different examination methods of chest radiography (CXR), digital tomosynthesis (DTS) and Computed tomography (CT) scan on the diagnosis of novel coronavirus pneumonia (COVID-19).Methods:
A retrospective analysis of three examination methods of chest CXR, DTS, and CT scan of COVID-19 pneumonia patients diagnosed in our hospital from January, 23, 2020 to February, 29, 2020. And we compared three different imaging methods to COVID-19 display ability of pneumonia intrapulmonary lesions.Results:
A total of 37 patients diagnosed as COVID-19 by nucleic acid testing were included. The CXR group (10/37) and DTS group (21/28) of 37 patients with COVID-19 pneumonia showed significant differences in intrapulmonary ground glass opacities (P<0.05); DTS group (21/28) and CT group (25/27) showed no statistically significant differences in intrapulmonary ground glass opacities (P> 0.05).Conclusion:
Comparison of the three imaging methods of COVID-19 pneumonia, the diagnostic efficiency of CXR is low, which is easy to be false negative and miss lesions; diagnostic resolutions of DTS are higher than CXR, which can improve the ability to display the fine structure of intrapulmonary lesions; CT scan shows the intrapulmonary of COVID-19 pneumonia low-density ground glass opacities and internal structures have equal capacity compared with DTS. Therefore, DTS and CT are the best choices for the image diagnosis of COVID-19 pneumonia.
