Contrast agents are frequently used in medical imaging such as computed tomography (CT) and magnetic resonance (MR) to reveal the final state of the body or organs. The states of the organs examined are obtained according to the absorption principle of x or gamma rays interacting with contrast agents. In this study, C17H22I3N3O8 (Iopamidol), C11H9I3N2O4 (Diatrizoic acid), BaSO4 (Barium sulfate) and C7H6O2 (Benzoic acid) compounds are examined to calculate effective atomic number (Zeff). Auto-Zeff and Direc-Zeff software have been used for calculation in an energy range from 100 keV to 10 MeV. According to the calculation results obtained have been compared with each other for each compound. According to these results, it was seen that the results were compatible with each other in low energy regions.
