Isovue-300 is a radiopaque (RAY dee oh payk) contrast agent. This medicine contains iodine, a substance that absorbs x-rays. Radiopaque contrast agents are used to allow blood vessels, organs, and other non-bony tissues to be seen more clearly on a CT scan or other radiologic (x-ray) examination.
Is isovue iso-osmolar?
Iodixanol (Visipaque) is an iso-osmolar contrast agent with an osmolality equal to that of blood at 290 mOsm/kg of water. Iopamidol (Isovue) has an osmolality of 796 mOsm/kg of water.
What is low osmolar contrast?
A major advance was the development of nonionic compounds. They are monomers that dissolve in water but do not dissociate. Hence, with fewer particles in solution, they are designated low-osmolar contrast media (LOCM).
Is omnipaque 300 low or high osmolar?
OMNIPAQUE 140, OMNIPAQUE 180, OMNIPAQUE 240, OMNIPAQUE 300, and OMNIPAQUE 350 have osmolalities from approximately 1.1 to 3.0 times that of plasma (285 mOsm/kg water) or cerebrospinal fluid (301 mOsm/kg water) as shown in the above table and are hypertonic under conditions of use.Is isovue-370 high or low osmolar?
Iopamidol (INN), sold under the brand name Isovue among others, is a nonionic, low-osmolar iodinated contrast agent, developed by Bracco Diagnostics. It is available in various concentrations, from 200 to 370 mgI/mL.
What is low osmolar?
Low osmolar contrast media (LOCM) have undergone further evolution with increased hydroxyl groups replacing carboxyl groups for additional solubility in water. The lower osmolality and increased solubility in water lowers LOCM toxicity.
Is isovue-300 non ionic?
ISOVUE-300 Classification: Nonionic radiopaque contrast media.
What is considered high osmolar contrast?
High-osmolarity contrast media (HOCM) are 5-7 times more hyperosmolar than blood, with osmolalities greater than 1500 mOsm/kg. Molecular structure of CM refers to the number of benzene rings.Is visipaque low osmolar?
Key Words: Visipaque 9 Iodixanol has the lowest osmolality of all available contrast media (290 mOsm/kg H2O), which represents a nearly two-thirds reduction in osmolality compared with low- osmolar contrast agents such as iohexol (844 mOsm/kg H2O).

Article first time published onIs Conray low osmolar?
Conray has an osmolarity of approximately 1000 mOsmol per liter, an osmolality of approximately 1400 mOsmol per kilogram and is, therefore, hypertonic under conditions of use. The viscosity (cps) is approximately 6 at 25°C and 4 at 37°C. The pH is 6.5 to 7.7. Conray is a clear solution containing no undissolved solids.
What is the difference between high and low osmolar contrast?
High-osmolality contrast media (HOCM) have an iodine to molecule ratio of 1.5 : 1. Low-osmolality, nonionic contrast media (LOCM) have an iodine to molecule ratio of 3 : 1. Isosmolar (isoosmolality) contrast media (IOCM) have an iodine to molecule ratio of 6 : 1.

What is ionic and non ionic contrast?
Iodinated contrast media can be divided into the two groups: ionic and non-ionic. Each group varies in their uses, properties and toxic effects. In non-ionic iodinated contrast media the iodine is bound to an organic (non-ionic) compound and has a low osmolality.
Is isovue-370 ionic or nonionic?

Is isovue-370 nonionic?
ISOVUE-370 Classification: Nonionic radiopaque contrast media.
What type of contrast is isovue-370?
Isovue-370 is a radiopaque (RAY dee oh payk) contrast agent. This medicine contains iodine, a substance that absorbs x-rays. Radiopaque contrast agents are used to allow blood vessels, organs, and other non-bony tissues to be seen more clearly on a CT scan or other radiologic (x-ray) examination.
What is isovue used for?
ISOVUE® is used for making blood vessels and other parts of the body visible to X-rays. Injection of ISOVUE® into the blood vessels dyes the blood vessels through which the blood flows. This allows the blood vessels in that area to be seen on an X-ray.
What is the difference between isovue and isovue M?
Isovue is not indicated for intrathecal use, while Isovue-M is specifically indicated for intrathecal use. When contrast medium is used for spinal injections, intrathecal injection of contrast or steroids is not expected.
How is isovue metabolized?
No significant metabolism, deiodination, or biotransformation occurs. Iopamidol is excreted mainly through the kidneys following intravascular administration. In patients with impaired renal function, the elimination half-life is prolonged dependent upon the degree of impairment. In the absence of renal dysfunction, …
Is visipaque safer than omnipaque?
Visipaque scored a big win in 2003 with a study in The New England Journal of Medicine finding that the iso-osmolar agent was significantly safer than a low-osmolar agent (Omnipaque) in preventing contrast-induced nephropathy in coronary angiography patients.
Is visipaque ionic or nonionic?
VISIPAQUE™ (iodixanol) Injection, 5,5´-[(2-hydroxy-1,3-propanediyl)bis (acetylimino)] bis[N,N´-bis(2,3-dihydroxypropyl)-2,4,6-triiodo-1,3- benzenedicarboxamide], is a dimeric, isosmolar, nonionic, water-soluble, radiographic contrast medium with a molecular weight of 1550.20 (iodine content 49.1%).
What is the difference between omnipaque and Visipaque?
Even at its highest concentration, 320 mg I/ml, Visipaque – based on the nonionic dimer iodixanol – is isoosmotic to blood plasma, whereas Omnipaque (300 mg I/ml) – based on the nonionic monomer iohexol – has an osmolality of about twice that of the plasma.
What type of contrast is visipaque?
Visipaque (iodixanol) Injection is a radiographic contrast medium indicated for intra-arterial digital subtraction angiography, angiocardiography (left ventriculography and selective coronary arteriography), peripheral arteriography, visceral arteriography, and cerebral arteriography.
Which type of contrast is associated with fewer adverse clinical events?
In general, non-ionic iodinated contrast media are associated with less adverse events than ionic contrast media (iodinated and gadolinium- based) [3,26].
What is negative contrast media?
Negative contrast agents (radiolucent) include air and other gasses. These do not block any x-ray photons, allowing x-rays to easily penetrate tissues containing the air. For example, the air filled lungs appear black on an x-ray because air easily penetrates through the lungs and travel on to expose the x-ray film.
Is metrizamide a low osmolality agent?
This unique property results in solutions of high iodine content yet with low osmolality. Metrizamide probably has a lower neurotoxicity than any other known water-soluble contrast agent.
Is iohexol high or low osmolar?
Iodixanol has the lowest osmolality of all available contrast media (290 mOsm/kg H2O), which represents a nearly two-thirds reduction in osmolality compared with low-osmolar contrast agents such as iohexol (844 mOsm/kg H2O).
What is the difference between omnipaque 300 and 350?
OMNIPAQUE 300 contains 647 mg of iohexol equivalent to 300 mg of organic iodine per mL; and OMNIPAQUE 350 contains 755 mg of iohexol equivalent to 350 mg of organic iodine per mL.
What is the difference between omnipaque and gastrografin?
The result was that Omnipaque retained its radiographic density in the small bowel better than Gastrografin. Omnipaque was thus a better alternative than Gastrografin in follow-through examinations of intestinal obstruction.
