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

Caption

Ultra-high-resolution photon-counting CT reveals bronchiolectasis: Axial CT lung images without contrast agent of a 70-year-old woman with persistent fatigue 401 days after COVID-19: 1.0mm image obtained with energy-integrating detector (EID) CT (A), and 1.0mm (B), 0.4mm (C) and 0.2mm (D) images obtained with photon-counting detector CT at the same level. Bronchiolectasis (white arrow) was not detected by EID CT but was found by PCD-CT. Ground-glass opacity detected in EID CT images (black arrows in A) was found to contain reticulations in PCD CT images (black arrows in B-D).
