Photon-Counting CT Shows More Post-COVID-19 Lung Damage

Caption

Ultra-high-resolution photon-counting CT reveals reticulations in lung areas classified as ground-glass opacity by high-resolution energy-integrating CT: Axial CT lung images without contrast agent of a 55-year-old man with persistent exertional dyspnea and chronic fatigue 399 days after COVID-19: 1.0mm image obtained with energy-integrating detector (EID) CT (A), and 1mm (B), 0.4mm (C) and 0.2mm (D) images obtained with photon-counting detector CT at the same level. Ground-glass opacities detected by EID CT (black arrows in A) were found to contain reticulations in PCD CT (black arrows in B-D).
