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

Caption

Comparison of image quality between energy-integrating detector and photon-counting detector CT images: Axial CT lung images without contrast agent of a 66-year-old man with persistent exertional dyspnea, chronic fatigue and anosmia 94 days after COVID-19: Subjective image quality was rated as ‘definitely better with likely effect on detectability of lung abnormalities’ for 1.0mm photon-counting detector (PCD) CT (B) compared with 1.0mm energy-integrating detector (EID) CT (A) images, ‘definitely better with unclear effect on detectability of lung abnormalities’ for 0.4mm (C) compared with 1.0mm (B) PCD CT images, and ‘similar without decrement or benefit’ for 0.2mm (D) compared with 0.4mm (C) PCD CT images.
