Abstract

Chest CT has proven to be a fundamental tool in COVID-19, with variable findings. The aim of this article is to analyze the prevalence of chest CT patterns in COVID-19 according to the evolution time of the pathology, and to define if there are dominant patterns in each phase. CT studies of COVID-19 patients performed in local clinics over a 3-month period were retrospectively reviewed. The studies were classified as: phase 1 (0-4 days), phase 2 (5-8), phase 3 (9-13) and phase 4 (≥14), and CT findings as: normal study, ground glass opacities (GGO), consolidations, crazy paving and architectural distortion. The predominant finding was identified as single or combined pattern. The results included 463 CT studies, 266 men (57.4%), aged 19–96 years. 18.1% of CT scans were normal (n=84), with a predominance in phase 1 (p<0.001). In relation to pathological CT, male patients predominated (p<0.006), with an age older than in normal CT (p<0.001). In all stages, GGO pattern predominated as the single pattern, similar in all phases (p=0.545), and always above 65%. In combinations of patterns, GGO with consolidation was the prevalent one, with a peak in phase 3 (63.3%). In conclusion, in all the phases of COVID-19, GGO prevail over other CT patterns. Initial CT phase may also be presented with a normal CT; intermediate stages (phase 2 and 3) with GGO in combination with consolidation; and phase 4 with a combination of GGO and architectural distortion.
