Patients that undergo the diagnostic test known as magnetic resonance angiography (MRA) are typically given an injection of Gadofosveset to help the medical team see their blood vessels more clearly. MRAs are a diagnostic tool used to detect and manage blockage in the arteries. This injection is classed as a gadolinium-based contrast agent (GBCA).
If you suffer from a blockage in the aorta or another blood vessel your doctor may use an MRA in the diagnosis and management of your condition. The Gadofosveset solution will be injected into your vein prior to the administration of the scan. This diagnostic procedure is conducted at a hospital or other clinic-like setting, and due to this, you will not need to self-administer the dosage. Patients will not be given this solution except as part of an MRA scan and therefore will not need to store the location in their homes.
There are a number of possible side effects that can occur with the use of Gadofosveset and patients with allergies may be more susceptible to having a negative reaction. It is important that your doctor is aware of all allergies that you may have prior to conducting this procedure. If you are concerned about allergies or other reactions that you may experience, your doctor or another member of your medical team can address them prior to the MRA.
Patients who suffer from kidney conditions may have difficulties with the administration of Gadofosveset. If you suffer from this condition your doctor will review the signs and symptoms of complications that you should look for. After the procedure is completed, you may wish to stay at the facility until you are certain that you are feeling well and any side effects that occurred with the use of Gadofosveset have passed.
The use of this solution has been known to cause anaphylaxis shock in some cases. It is important that patients familiarize themselves with this reaction and know to immediately signal for help should they experience it. Be sure to ask any questions or voice any concerns when your doctor or nurse review the potential side effects and reactions that may occur from the use of Gadofosveset prior to your MRA scan.
Because this solution is administered as part of an MRA procedure you will have an entire medical team close by to deal with any serious side effects that you may experience. Many patients report of discomfort, such as itching, at the site of the injection. Any such reaction should dissipate after a few moments, but should any effect that you experience worsen or last longer than several minutes, it is advisable to notify one of the medical team that is administering the scan.

You will be informed of any changes that you may be required to make such as not eating or drinking for a certain period of time prior to the procedure. Present all questions and concerns that you may have to your doctor before your scan and be sure that you feel that they are addressed in a complete manner before proceeding.
