Figure 1

Box-plot diagram displaying attenuation in liver and liver attenuation index (LAI) in (A) true non-contrast (TNC), (B) virtual non-contrast (VNC) from CT angiography of the chest (VNC-Chest) and abdomen (VNC-Abdomen). (A) Patients receiving amiodarone treatment showed significantly higher liver attenuation and LAI indicating that amiodarone accumulation in the liver artificially increased attenuation values of the liver. (B) Contrary to TNC, liver attenuation and LAI in VNC-Chest and -Abdomen images of patients treated with amiodarone were not higher compared to patients that have not been treated with amiodarone indicating that VNC not only subtracts iodine from contrast media but might also be able to subtract the iodine in amiodarone accumulated in the liver.
