Magnetic resonance angiography (MRA) is a specialized imaging technique that uses magnetic resonance to visualize blood vessels. The test provides a detailed picture of the blood vessels without the need to inject contrast agents intravenously.
Magnetic resonance angiography is primarily used in the diagnosis of vascular diseases. Indications for the study:
- diagnosis of aneurysms, hemangiomas, arterial stenosis and other vascular malformations,
- diagnosis of strokes, atherosclerosis and cancer,
- thrombosis,
- vertebrobasilar syndrome.
Contraindications to the study:
- implanted electrical devices (defibrillator, pacemaker, neurostimulator, etc.),
- metal bodies in soft tissues or metal fragments in the vicinity of vessels, parenchymal organs, eyeballs.
The test is not recommended for women in the first trimester of pregnancy. Claustrophobia may also be a contraindication to the test.
