NAEOTOM Connect - The photon-counting CT excellence community for NAEOTOM Alpha class systems by Siemens Healthineers. The modern way of radiology.
Access publication Key message Over roughly 25 years, combined advances in CT hardware, acquisition, and reconstruction have enabled approximately 2- to 10-fold radiation-dose reductions, but dose reduction should be judged against preserved diagnostic performance, not merely lower image noise. Practical implication: Dose…
Dedicated photon-counting CT protocols enabled up to 40% radiation dose reduction and 33% iodine reduction while maintaining diagnostic image quality for thoracoabdominal aortic CTA. Even the combined low-dose/low-contrast (LD/LC) protocol provided objective and subjective image quality comparable to third-generation…
PCCT achieved lower radiation dose and higher signal-to-noise ratio (SNR) than energy-integrating CT across pediatric head phantom models, demonstrating improved dose efficiency for neuroimaging. The greatest radiation dose reduction was observed in the 10-year-old phantom (9% lower CTDIvol at clinically relevant IQL 200),…
