Conclusion In performing radiopacity evaluation, it is important to note that the radiopacity of a device is influenced by the setting of the x-ray source anode voltage, which can range between 20 and 80 kV. The FDA guidelines suggest the use of x-ray inspection for the determination of the radiopacity of intravascular stents and delivery systems.The resulting images and their interpretation will depend on the methodology and x-ray systems that are used as well as an understanding of the factors that influence the appearance of the x-ray image.
