Professional MR angiography in Kharkiv, Kherson, Cherkassy - ScanLife
Angiography is a minimally invasive medical test that helps physicians diagnose and treat medical conditions. Angiography uses one of three imaging technologies and, in some cases, a contrast material to produce pictures of major blood vessels throughout the body.
Angiography is performed using:
- x-rays with catheters
- computed tomography (CT)
- magnetic resonance imaging (MRI)
In magnetic resonance angiography (MRA), a powerful magnetic field, radio waves and a computer produce the detailed images. MR angiography does not use ionizing radiation (x-rays).
MR angiography may be performed with or without contrast material. If needed, the contrast material is usually injected using a vein in the arm.
MR angiography is used to examine blood vessels in key areas of the body, including the:
Physicians use the procedure to:
- identify disease and aneurysms in the aorta, both in the chest and abdomen, or in other major blood vessels.
- detect atherosclerosis disease in the carotid artery of the neck, which may limit blood flow to the brain and cause a stroke.
- identify a small aneurysm or arteriovenous malformation inside the brain.
- detect atherosclerotic disease that has narrowed the arteries to the legs and help prepare for endovascular intervention or surgery.
- indicate disease in the arteries to the kidneys or visualize blood flow to help prepare for a kidney transplant.
- guide interventional radiologists and surgeons making repairs to diseased blood vessels, such as implanting stents or evaluating a stent after implantation.
- detect injury to one of more arteries in the neck, chest, abdomen, pelvis or extremities in trauma patients.
- evaluate arteries feeding a tumor prior to surgery or other procedures such as chemoembolization or selective internal radiation therapy.
- identify dissection or splitting in the aorta in the chest or abdomen or its major branches.
- show the extent and severity of atherosclerosis in the coronary arteries and plan for a surgical operation, such as a coronary bypass.
- sample blood from specific veins in the body to detect any endocrine disease.
- examine pulmonary arteries in the lungs to detect pulmonary embolism (blood clots from leg veins).
- screen individuals for arterial disease, especially patients with a family history of arterial disease or disorders.
