Quantitative and qualitative lung parameters in photon-counting CT: comparison of ultra-low-dose with standard low-dose protocols.
OBJECTIVES Photon-counting CT (PCCT) enables dose reduction beyond energy-integrating CT, but ultra-low-dose acquisitions may impair assessment of airways and lung parenchyma. We evaluated the impact of ultra-low-dose (ULD) PCCT on quantitative and qualitative lung parameters. METHODS In this prospective study, 101 p...
