However, it comes with a potential risk to the patient in the form of allergic reactions. The aim of this research is to study the effects of iodine contrast media on endothelial cells in an in vitro system at various concentrations, specifically investigating their impact on cell viability, cell cycle, and apoptosis in the treated cells within the field of diagnostic radiology. Our results showed that in iodine contrast media, when the concentration was within the range of 2.5-50 mgI/ml, cell viability decreased by 50%. Conversely, exposure to ioversol at concentrations between 12.5 and 50.0 mgI/ml resulted in a notable increase in the percentage of total apoptotic cells, including both early and late apoptosis. In conclusion, our in vitro investigation sheds light on the effect of iodinated contrast media on endothelial cell viability, cell cycle progression, and apoptosis. These findings contribute valuable insights to ensure the safety of their use, aligning with guidelines in radiological procedures. Further research and adherence to established guidelines are crucial for refining our understanding and promoting the safe application of iodinated contrast media in the field of radiology.
