When is Visipaque used?

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. Visipaque is used to help diagnose certain disorders of the brain, blood vessels, heart, kidneys, and other internal organs.

What is Visipaque contrast?

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.

How do you take Visipaque?

The usual dose is: You will usually have Visipaque injected into a blood vessel before or during the X-ray examination or you may be asked to drink it or if you are a child can get it rectally. The amounts injected may vary depending on the type of examination, the technique used and your age and weight.

Is Visipaque the same as omnipaque?

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.

Why is iodine a contrast agent?

Iodine has a particular advantage as a contrast agent because the k-shell binding energy (k-edge) is 33.2 keV, similar to the average energy of x-rays used in diagnostic radiography 1. When the incident x-ray energy is closer to the k-edge of the atom it encounters, photoelectric absorption is more likely to occur.

Is there iodine in visipaque?

VISIPAQUE™ VISIPAQUE Injection is provided as a ready-to-use sterile, pyrogen-free, colorless to pale yellow solution, in concentrations of 270 and 320 mg of organically bound iodine per mL (550 and 652 mg of iodixanol per mL, respectively).

Is visipaque a high or low osmolar contrast?

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).

What is OMNIPAQUE used for?

OMNIPAQUE is one of a group of medicines known as “contrast media” for diagnostic use. OMNIPAQUE is used in X-ray examinations in many different parts of the body for adults and children. It can make it easier to find and see abnormalities, and improves the diagnostic information needed by the doctor.

Is contrast dye nephrotoxic?

Many experimental studies have been in favor of the existence of CI-AKI. Contrast drugs have been shown to be nephrotoxic, regardless of their osmolality, by causing the changes outlined in the following sections.

What is the difference between high and low osmolar contrast?

Low-osmolarity contrast media (LOCM) is actually a misnomer, since these agents have osmolalities of 600-900 mOsm/kg and so are 2-3 times more hyperosmolar than blood. High-osmolarity contrast media (HOCM) are 5-7 times more hyperosmolar than blood, with osmolalities greater than 1500 mOsm/kg.

Does omnipaque make you poop?

Omnipaque contains iodine which is commonly used in Radiology. The liquid may have a slight laxative effect.

Is it safe to drink omnipaque?

Omnipaque liquid (bowel preparation) Omnipaque is safe to drink. If you have had a severe allergic reaction to x-ray contrast in the past we may need to give you an alternative preparation. Please telephone us for further advice if you think you may have an allergy (see attached letter).
