Image Quality and Radiation Dose Associated With Cardiac Scans in Modern CT Scanners

200 participantsStarted 2022-02-20

Plain-language summary

The main objective of this study is to evaluate the dose efficiency of coronary CT angiography (CTA) using a photon counting detector CT (PCD-CT) with the dose efficiency of coronary CT angiography of prior CT generations. 100 patients with a clinical indication for coronary CT angiography will be prospectively enrolled and undergo coronary CTA on a PCD-CT. For comparison, a matched retrospective cohort of 100 patients will be created who had undergone on a prior scanner generation (retrospective cohort).
