First-generation clinical dual-source photon-counting CT: ultra-low-dose quantitative spectral imaging

ConclusionsThis paper reports the first experiences with a clinical dual-source PCCT. PCCT provides reliable HUs without disruption from electronic background noise for a wide range of dose values. Diagnostic benefits are not only for quantification at an ultra-low dose but also for imaging of obese patients.Key PointsPCCT scanners provide precise and reliable Hounsfield units at ultra-low dose levels.The influence of electronic background noise can be removed at ultra-low-dose acquisitions with PCCT.Both spectral platforms have high performance along a wide range of radiation exposure levels, with PCCT outperforming at low radiation exposures.
