Clinical course of COVID-19 in our patient. The PaO2/FiO2 values at different time points are depicted. Dual-energy computed tomography (DECT) was performed on days 12 and 19 of the onset of the disease. The figure also presents the timeline of the administered therapies. NHFT, nasal high flow therapy.

The course of treatment after admission and the findings of DECT are shown in Figures 1 and 2, respectively.
Series of (A) images obtained with plain computed tomography of the lung and (B) perfused blood volume images generated using dual-energy computed tomography, both performed on days 12 and 19 after onset of disease. The orange area in the figure indicates the presence of blood flow.

The course of treatment after admission and the findings of DECT are shown in Figures 1 and 2, respectively. Follow-up DECT imaging was performed on day 19 (day 9 after admission) after the onset of the disease, and although the lesion did not improve on plain CT, DECT findings on days 12 and 19 showed apparent improvement in the blood flow deficit (Fig. 2).
