Serial lung perfusion evaluation in a COVID-19 patient. (a–c) Electrical impedance tomography (EIT) perfusion images obtained at days 6, 8, and 18. Images were generated with Enlight 1800 (Timpel SA, São Paulo, Brazil) using the first-pass kinetics method. The lung is divided into four quadrants (regions of interest). Colour scale was adjusted by linear normalisation. (d) Axial CT pulmonary angiography image shows segmental and subsegmental pulmonary emboli in the right upper lobe (red arrow). (e) Axial CT pulmonary angiography image shows resolution of the pulmonary artery filling defect (red arrow) in comparison with the previous image. Day, day from admission to emergency department; CRS, respiratory system compliance; ΔP, driving pressure.
