Correlation of consolidation between CXR and CT: a 68-year-old Chinese man with COVID-19, and relevant past medical history of smoking and hypertension, presented with shortness of breath on day 14 of symptom onset. He presented with an oxygen saturation of 85% on room air and was intubated on arrival. (A) Initial chest radiograph was scored as follows: right middle zone grade 1 density score 2, right lower zone grade 3 density score 3, left middle zone grade 4 density score 3 and left lower zone grade 4 density score 2 (CRS 31); (B) CT thorax done on the same date confirmed dense consolidation in both lungs, worse in the lower lobes.
