Stenosis quantification in high-pitch photon-counting coronary CT angiography: in vitro and in vivo impact of reconstruction kernel types and sharpness levels
High-pitch PCD-CCTA images can be reconstructed with different kernels. Reconstructions with different kernels showed comparable accuracy on coronary stenosis quantification. In vitro, Bv40 reconstructions showed superior measurement accuracy to the reference. In vivo, reconstructions with the Bv kernel had the highest interobserver reliability. Reconstruction with kernel Bv40 should be considered in high-pitch PCD-CCTA.
