Evaluation of low-dose chest scans for coronary artery calcium scoring using photon-counting computed tomography with different slice thicknesses and iterative reconstruction levels
The LD-CT scan derived from photon-counting detector CT demonstrated excellent agreement with the standard CACS scan in terms of CACS and significantly reduced radiation dose. The reconstruction protocol using a 1.5-mm slice thickness with QIR level 1 improved coronary artery calcium detection, quantification, and risk categorization.
