Impact of Photon-Counting CT Acquisition Modes on Coronary Stenosis Assessment and Radiation Dose: A Phantom and Clinical Evaluation.
INTRODUCTION Photon-counting detector computed tomography (PCD-CT) offers high spatial resolution and dose-efficient coronary CT angiography (cCTA), but protocol selection, especially optimal acquisition mode, requires balancing spacial resolution, temporal robustness and radiation exposure. This study evaluated variou...
