Correlation between CT attenuation value and iodine concentration in vitro: Discrepancy between gemstone spectral imaging on single‐source dual‐energy CT and traditional polychromatic X‐ray imaging

Introduction: To assess the relation between CT attenuation value and iodine concentration in vitro, using gemstone spectral imaging (GSI) with single‐source dual‐energy CT and traditional polychromatic X‐ray imaging (TPXI), respectively.
