Contrast media is used in a number of types of examinations to highlight blood vessels and blood flow in various parts of the body. Contrast is a clear fluid that shows up as white on x-ray images. It is usually given via an injection into a vein in the arm.
All our practices use non-ionic contrast media, which is considered the safest available intravenous contrast media in use today.
Patients are advised to expect a sensation of heat, an unusual taste or smell, or a sensation in their bladder during and immediately following the contrast injection. These symptoms are considered normal and last for only a short period of time.
The contrast is filtered from the body by the kidneys and is excreted in the urine within 3-5 hours of the initial injection. Patients are encouraged to drink additional clear fluids following their examination to assist kidney filtration.
Occasionally, patients experience minor allergic reactions such as hives. More rarely, a major allergic reaction can occur. Our Doctors and staff are trained in the management of allergic reactions and all sites that administer intravenous contrast media are equipped with emergency medications, should a patient experience a severe reaction.
Patients with a history of allergic reactions, asthma, diabetes, kidney failure or heart disease may require additional precautions to minimise possible complications from a contrast injection. Any patient who suffers a contrast reaction should present to their nominated treating doctor for follow up.
