Data analysis of lung abnormalities detected by computed tomography (CT) of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-exposed macaques via percent change in lung hyperdensity (PCLH).

Top: representative axial CT images in three SARS-CoV-2-exposed macaques for each indicated study day (D). The gray scale represents radiodensity in Hounsfield units (HU). Bottom: percentage change in volume of lung hyperdensity (PCLH) measured over time in the same SARS-CoV-2 inoculated macaques shown in the upper panel. Adapted from [8].
