About this study

Data collected in this study includes an assessment of image quality parameters including spatial resolution, image contrast, and noise that will evaluate the product and how this photon-counting CT technology can be used to reduce the overall radiation dose in CT imaging, and enhance clinical applications for CT technology.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Age >50 years
  • Male
  • Normal renal function per standardized guidelines (GFR > 60 mL/min)
  • Previous CT examination at KS no more than 12 months prior to the study examination
  • Signed informed consent

Exclusion criteria

  • Iodine contrast is contraindicated.

Treatment and study plan

CT with a photon-counting detector

Device

Enrolled subjects will complete an exam using the photon-counting CT, with or without IV contract as indicated. Images will then be compared with the previously acquired CT conducted as standard of care.

Primary outcomes

  1. Evaluate feasibility of the photon-counting CT in a clinical setting.

    Time frame: 1 year

    The primary objective of this study is to collect and evaluate raw CT scan data collected using the photon-counting CT.

Secondary outcomes

  1. Collect feedback on performance and images generated on the photon-counting CT.

    Time frame: 1 year

    Gather feedback on the performance and image quality of the reconstructed images produced by using the photon-counting CT.
