Coronal, axial, and sagittal CT images all presented scattered ground glass shadows in both lower lobes and subpleura, some with consolidation (white arrows). g-i Images of a 49-year-old woman infected with Delta variant virus who was fully vaccinated (CT score of 6). Coronal, axial, and sagittal CT images all presented scattered ground glass shadows in both lower lobes and subpleura, some with consolidation (white arrows). Coronal, axial and sagittal CT images showed subpleural ground glass shadows in the posterior basal segment of the right inferior lobe, with local consolidation (white arrow)
