CT manifestations of coronavirus disease-2019: A retrospective analysis of 73 cases by disease severity

Chest CT for detecting COVID-19: a systematic review and meta-analysis of diagnostic accuracy

“…With regard to the flow and timing domain, we noted that 11 studies had an ambiguous risk of bias due to the absence of mean interval data between chest CT and the RT-PCR assay [6,7,[10][11][12][13][14]. And, the remaining studies reported a reasonable interval between chest CT and the RT-PCR assay (1-3 days) [5,8,9,15,19].…”

“…Of these patients, 2689 patients had positive RT-PCR results. Fourteen studies only enrolled patients diagnosed as COVID-19 by RT-PCR [6][7][8][9][10][11][12][13][14][16][17][18][19][20]. Therefore, we could only calculate sensitivity from the information provided in these studies.…”

“…Therefore, we could only calculate sensitivity from the information provided in these studies. Three studies were conducted in Wuhan [5,8,12]; 12 studies were conducted in the other regions, and the remaining one collected data throughout China [6,7,[9][10][11][14][15][16][17][18][19][20]. The mean or median age of patients ranged from 37 to 62.…”

“…Some studies show that extensive GGOs and consolidation are more common on the patients with decreased oxygen saturation or requiring mechanical ventilation when compared with these cases without respiratory distress. 4 Moreover, pleural effusion could be seen on the critical case. 4,5 However, at this point there is no standalone imaging finding which predict if the condition of these patients with initial mild findings will rapidly progress to adult respiratory distress syndrome.…”
