AB  - 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 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).
