The figure shows examples of CAD as displayed by conventional calcium scoring protocol (A, B, C; inside white circles and ellipses) and corresponding CT coronary angiography images (D, E, F; inside white circles and ellipses) obtained with photon counting CT—PCCT technology (NAEOTOM ALPHA, Siemens Healthineers). It is very clear that the detection and phenotyping of calcifications is going to be dramatically improved by this technology. These improvements will also determine a much better visualization of high attenuation/density structures such as coronary artery stents (G) in which even stent structs will be easily differentiated (arrows) together with in-stent re-stenosis (arrow-head).
