Spectral photon-counting CT evaluates carotid plaque and stenosis metrics, suggesting enhanced diagnostic capabilities.
Low-energy PCD-CT reconstructions enhance CNR and sharpness while maintaining consistent plaque and stenosis measurements. The PL algorithm may improve the assessment of calcified plaques, where conventional reconstructions may overestimate stenosis. PCD-CT shows promise for advanced plaque composition evaluation, but further validation against MRI and histology is warranted.
