Coronary Artery Calcium Scoring with Photon-Counting Detector CT: Ultra-Low-Dose Scan Versus Coronary CT Angiography-Derived Images.
PURPOSE To compare coronary artery calcium (CAC) scores from ultra-low-dose true non-contrast (TNC), virtual non-contrast (VNC), and virtual non-iodine (VNI) images with standard TNC on a dual-source photon-counting detector CT (PCD-CT). METHODS In this prospective single-center study (January 2025-March 2026), patie...
