Presentation of Organ Dose and Effective Dose Conversion Factors in Dual-Energy Computed Tomography: A Monte Carlo Simulation Study

Background: The same conversion factors (k-factors) of Single CT (SECT) are applied to estimate the Effective Dose (ED) in Dual Energy Computed Tomography (DECT). However, k-factors for different organs need independently validating DECT, due conditions DECT. Objective: This study aimed calculate organ dose and imaging protocols (liver, chest, cardiac, abdomen) male female phantoms. Material Methods: Monte Carlo Simulation used N-Particle (MCNP) code modeling a Siemens Somatom Definition Flash dual-source scanner. dose, length product, were calculated Medical Internal Radiation (MIRD) Results: For phantom, liver, abdomen-pelvis equal 0.020, 0.012, 0.016, 0.014 mSv.mGy−1cm−1, respectively. corresponding values 0.026, 0.023, 0.036, 0.018, These DECT from those SECT, especially phantom. Conclusion: can be as reference estimation ED
