Difference between the effective atomic numbers and monochromatic CT numbers for commercially available dual-energy CT

ConclusionsThe accuracy of the Zeff values with dual-source DECT was good in agreement in the Multi-Energy phantom. The single-source fast kilovoltage switching type DECT could reduce the noise and accuracy of the Zeff values than that with single-source DECT for the varying concentrations of iodinated contrast medium.Advances in knowledgeThe accuracy and precision of the Zeff values of the contrast medium with the single-source fast kilovoltage switching type DECT could be sufficient with human equivalent materials.
