It is difficult to distinguish COVID-19 pneumonia from other viral pneumonia on CT findings alone; however, we emphasize the utility of chest CT to detect early change of COVID-19 in cases which RT-PCR tests show negative results. d Follow-up CT 7 days after admission (d1, axial image; d2, ray-summation image; d3, pseudo color MIP; d4, coronal image) shows multifocal bilateral ground-glass opacities and improvement of mixed groundglass opacities and consolidation in left upper lobe.
