Background: Photon-counting detector computed tomography (PCD-CT) may influence imaging characteristics for various clinical conditions due to higher signal and contrast-to-noise ratio in virtual monoenergetic images (VMI). Radiomics analysis relies on quantification of image characteristics. We evaluated the impact of different VMI reconstructions on radiomic features in in vitro and in vivo PCD-CT datasets.

- The study compares coronary artery calcium scores obtained through photon-counting detector (PCD) and conventional energy integrating detector (EID) computed tomography (CT) in both phantom tests and actual patients.
- Results indicated that PCD-CT showed more accurate measurements of coronary artery calcium volumes compared to EID-CT, although the scores from both methods correlated closely.
- Despite the correlation, the lower scores from PCD-CT resulted in a slight reclassification of patients to a lower risk category, suggesting that PCD-CT may provide different clinical implications despite its accuracy.
