Reader evaluation results (based on a 5-point Likert scale) on stent appearance (SA) and blooming (BL) at 150-mm and 50-mm field-of-view (FOV) for silicon-based photon-counting CT (Si-PCCT) and energy-integrating detector CT (EIDCT) images. Stent appearance was found to be insufficient (score 1) for 12.5% (4 out of 32) of the EIDCT images. Two EIDCT images (out of 32) were perceived as containing severe blooming artefacts (score 1)
