Diatrizoate Meglumine
A high-osmolar ionic contrast medium used in various imaging studies. Potential reactions involve sensation of warmth, vomiting or nausea, and rare severe reactions.
High-Osmolar Contrast Media (HOCM)
These are ionic agents used in various imaging procedures, associated with higher risk of adverse reactions. Potential reactions include pain, warmth sensation, and more severe allergies.
Iohexol
A nonionic, low-osmolar contrast medium used for angiography, urography, and other imaging tests. Potential reactions include hives, itching, and rare severe allergic reactions.
Ultrasmall Superparamagnetic Iron Oxide (USPIO)
Used in MRI for liver and lymph node imaging. It is also being researched for other applications. Potential reactions include localized pain and allergic reactions.
Sulfur Hexafluoride
An ultrasound contrast agent used to enhance the echogenicity of blood and to evaluate left ventricular function. Potential reactions are usually mild and may include altered taste or discomfort.
Copper-based Contrast Agents
Experimental agents used in certain types of radiological research. Potential reactions are still under investigation as it's not widely used clinically.
Oral Iodinated Contrast
Used in gastrointestinal studies like CT enterography. Potential reactions include gastrointestinal discomfort, nausea, and vomiting.
Optiray
A brand name for ioversol, a nonionic and low-osmolar contrast medium used for general radiography involving the body's cavities and vessels. Reactions include feeling of warmth, metallic taste, and rare anaphylactic reactions.
Barium Sulfate
Used for radiographic examinations of the gastrointestinal (GI) tract. Potential reactions include constipation, impaction, and aspiration.
Manganese-based Contrast Agents
Used in MRI to visualize the liver and biliary tract. Potential reactions are generally mild but can include headaches, nausea, and dizziness.
Perflutren Lipid Microsphere
Used in echocardiography to enhance the borders of the heart chambers. Potential reactions include allergenicity, transient side effects such as headache, and nausea.
Iodixanol
An iso-osmolar contrast agent used in vascular imaging. Potential reactions include nausea, a sensation of heat, and rare cases of contrast-induced nephropathy.
Microbubble Contrast Agents
Used in ultrasound imaging to enhance the echogenicity of blood. Potential reactions include allergic reactions, headache, and nausea.
Intravenous Iodinated Contrast
Administered intravenously to enhance the contrast of CT images of organs and vessels. Potential reactions include a feeling of warmth, taste change, and in rare cases, anaphylaxis.
Iron Oxide Nanoparticles
Used in MRI to image the liver, spleen, and bone marrow. Potential reactions can include back pain, arthralgia, and hypersensitivity reactions.
Oil-based Contrast Media
Used in lymphangiography and some hysterosalpingography procedures. Potential reactions include inflammation, infection, and granulomas.
Low-Osmolar Contrast Media (LOCM)
These are non-ionic agents with a lower risk of adverse effects than HOCM. Used widely in CT and X-ray imaging. Potential reactions include mild allergy-like reactions and a lower incidence of nephrotoxicity.
Visipaque
A brand name for iodixanol, used in angiographic procedures including coronary angiography. Potential reactions include a sensation of pressure, headache, and in rare cases, cardiac effects.
Gadolinium-based Contrast Agents (GBCAs)
Used in MRI to improve visualization of blood vessels, inflammation, and tumors. Potential reactions include nephrogenic systemic fibrosis, allergic reactions, and headache.
CO2 (Carbon Dioxide)
Used as a negative contrast agent in vascular and nonvascular interventions. Potential reactions include embolism, but is minimal due to its high solubility in blood.
Iodinated Contrast Media
Used in CT scans and X-rays to enhance vascular structures and organs. Potential reactions include allergic reactions, nephrotoxicity, and extravasation.
Iso-Osmolar Contrast Media (IOCM)
Non-ionic contrast media with osmolality similar to blood plasma; used to minimize side effects. Potential reactions include less pain and discomfort during administration.
Bismuth Subsalicylate
Not a typical contrast agent but can be used in radiology for gastrointestinal imaging. Potential reactions are rare but can include salicylate toxicity or allergic reactions.
Air Contrast Media
Used in double contrast barium enemas to improve colonic visualization. Potential reactions include discomfort, bloating, and risk of bowel perforation.
Ethiodized Oil
Used primarily in lymphography and sometimes in hysterosalpingography. Its oily nature can lead to reactions such as embolization, hypersensitivity reactions, and inflammation.
