Abstract: Objective To investigate the imaging manifestations of COVID-19 with different clinical types.Methods Computed tomography(CT)imaging data of 71 patients diagnosed with COVID-19 were retrospectively analyzed. The clinical characteristics, imaging characteristics, the dominant distribution of lesions and improvement time of patients with common type,severe type and critically severe type were analyzed statistically. Results Among the 71 patients,12 were mild type, 45 common, 14 severe and critically severe. For the clinical manifestations, critically severe and severe patients had symptoms of fatigue,chest tightness and dyspnea(6/14,42.9%;4/14,28.6%),It was more obvious than those common type(2/45,4.4%;0) and mild type (0;0), with a statistically significant difference (P=0.001, 0.002).The C-creative protein level of patients with common type(30/45,66.7%), severe and critically severe type(9/14,64.3%) was higher than that of mild type(2/12,16.7%), with a statistically significant difference (P=0.005).For the CT manifestations:more than three lobes were involved in the lesions:the ratio(13/14,92.9%) in the severe and the critically severe type was higher than that in the common type(26/45,57.8%). For the severe and the critically severe type, the ratio of (12/14,85.7%) the lesions distribution in the peripheral and central lung was higher than the common type(20/45,44.4%). The lesions including consolidation, interlobular septal thickening in the severe and the critically severe type were more serious than those in the common type. These manifestations showed statistically significant differences between the two groups(P values were 0.036, 0.007, 0.004, 0.002).The followed up of 22 patients indicated that the peak of CT manifestations and the improvement of the condition all occurred 10 days later (40.96%,45.5%).Conclusion COVID-19 patients with common type and those with severe and critically severe type have different characteristics in the location of the lesions, the density of the lesion, the degree of consolidation and so on. Most of the patients may improve after 10 days of onset.
