Key Points

The study aims to evaluate how photon-counting CT (PCCT) improves image quality while reducing radiation output in 4D parathyroid imaging.
Quantitative comparison of image quality between photon-counting CT and conventional EIDCT.
Assessment of radiation output levels during multiphase 4D parathyroid imaging.
Focus on arterial-phase acquisitions at lower thyroid levels.
PCCT significantly reduces radiation output compared to EIDCT.

Abstract

PCCT substantially reduces CT scanner radiation output while improving quantitative image quality in multiphase parathyroid 4DCT, including technically challenging arterial-phase acquisitions at the lower thyroid level, supporting its technical advantage over conventional EIDCT.
