Spectral ultrahigh-resolution photon-counting CT for coronary stent imaging: evaluation in a dynamic phantom
The combined value of spectral UHR CT for stent imaging remains largely unexplored. UHR PCD-CT showed the highest lumen visibility and sharpest strut delineation, whilst being prone to motion artifacts. Spectral reconstructions complement UHR by reducing artifacts and stabilizing image quality, especially at higher heart rates.
