Coronary calcium scoring potential of large field-of-view spectral photon-counting CT: a phantom study

The aim of the current study was, first, to assess the coronary artery calcium (CAC) scoring potential of spectral photon-counting CT (SPCCT) in comparison with computed tomography (CT) for routine clinical protocols. Second, improved CAC detection and quantification at reduced slice thickness were assessed.Raw data was acquired and reconstructed with several combinations of reduced slice thickness and increasing strengths of iterative...
