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

Journal of Medical Imaging and Radiation Oncology, 05/24/2012

Owing to the better correlation coefficients between CT attenuation value and iodine concentration, gemstone spectral imaging (GSI) may be a preferred method for quantitative measurement compared with traditional polychromatic X–ray imaging (TPXI).
