Knowledge About Non Ionic Contrast Medium
2021/10/04

Non ionic contrast medium is the second generation of CT contrast medium. For advantages of non ionic contrast media, compared with the first generation of ionic contrast medium, the non ionic contrast medium has greater water solubility. In addition, it does not ionize in water, which has the advantages of low viscosity and low osmotic pressure. Clinically, the incidence and severity of toxic side effects of the non-ionic contrast medium are significantly lower than that of the ionic contrast medium.
