Iohexol osmolality
Web2 jan. 2024 · The osmolality of iohexol ranges from 322 mOsm/kg-approximately 1.1 times that of blood plasma-to 844 mOsm/kg, almost three times that of blood. Despite this difference, iohexol is still considered a low-osmolality contrast agent; the osmolality of older agents, such as diatrizoate, may be more than twice as high. From Wikipedia. … WebThese agents include iohexol ( Omnipaque ), iopamidol (Isovue), ioversol (Optiray), and iopromide (Ultravist). Another approach to reducing osmolality was to develop dimeric molecules, essentially two tri-iodinated CM molecules joined together.
