Gadolinium might be an alternative, stop-gap solution for interventional procedures during the current iodine contrast shortage.
Current alternatives include carbon dioxide, gadolinium, and dilute ICM. Each of these alternatives has its own unique features and limitations. In the present review article, the current alternatives to ICM are explored, with a focus on the applications and restrictions of each.
renal disease or contrast allergy pose limitations on the use of ICM. In such cases, alternative contrast media may be used to carry out the procedure. Current alternatives include carbon dioxide, gadolinium, and dilute ICM. Each of these alternatives has its own unique features and limitations.
A contrast dye allergy, though rare, can happen after a CT scan or MRI. Learn what contrast dye is and how doctors prevent and treat a reaction.
Recent studies have suggested a third and potentially more effective option: administer an alternative ICM with a chemical structure dissimilar to that of the ICM that caused the prior reaction. For example, if the patient’s previous reaction was to iohexol, using iopromide may reduce the risk of a repeat reaction.
There are three broad kinds of contrast available: IV, PO, and PR (rectal). IV contrast is either gadolinium for MRI or iodinated contrast for CT. PO contrast for all ER and inpatient CT scans is dilute iodinated contrast (same agent used for IV contrast in CT). Barium is available as an alternative for ER patients with allergic reactions to ...
This critical review outlines the motivations, technical obstacles, problems, and the most recent published progress toward the creation of alternatives to the existing gadolinium-based contrast agent.
Finding the Optimal Alternative for Immediate Hypersensitivity to Low-Osmolar Iodinated Contrast. Invest Radiol 2021;56(8):480–485.
A contrast agent doesn't make you feel better or treat what's ailing you. But by making CT scans clearer, contrast might be crucial in helping your doctor make the right diagnosis.
Contrast echocardiography is a technique for improving echocardiographic resolution and providing real-time assessment of intracardiac blood flow. Agitated saline contrast provides contrast in the right heart and enables detection of right to left shunts.
