    Document: The copyright holder for this preprint (which was not peer-reviewed) is . https://doi.org/10.1101/2020.03.24.20042432 doi: medRxiv preprint There are several limitations in our study. First, the method is to compare the difference of CT imaging features between confirmed patients and non-confirmed patients of COVID-19. Some early lesions might not be visible on chest CT since the maximum incubation period is 14 days or even more [6] . So the expression of time may not be precise enough according to the development of this disease. Second, the current gold standard for the diagnosis of COVID-19 is merely RT-PCR test [6] . Since the test samples are mostly pharynx swabs rather than bronchoalveolar lavage fluid (BALF), it might still present false negative results after repetitions.
