Web25 aug. 2024 · In regard to iodine concentrations, non-ionic monomers (low-osmolar CAs) have higher osmolalities and lower viscosities than non-ionic dimeric CAs (iso-osmolar CAs) in vitro. Small changes in concentration can cause large changes in CA viscosity, because the viscosity of CA increases exponentially, as a function of iodine … Webnol (Visipaque ) and hypo-osmolar agents like iopamidol (Optiray ). Avoid iohexol (Omnipaque ) and ioxaglate as these were associated with a higher incidence of CIN in trials [9 ]. Avoidance of hyper-osmolar (1,500 2,000 mOsm/kg) contrast media in all patients.
