MR Angiography (Angio MRI or Magnetic Resonance Angiography \u2013 MRA) is an advanced exam that allows non-invasive assessment of the blood vessels of the human body, without the use of ionizing radiation. It is especially used to study arteries and veins in various regions, such as the brain, neck, chest, abdomen, kidneys and lower limbs.<\/span><\/p>\n

What is a MR Angiography?<\/span><\/h2>\n

MR Angiography is a specialized MRI technique focused on the analysis of blood vessels. It provides high-definition images of arteries and veins, making it easier to diagnose stenoses, occlusions, aneurysms, vascular malformations and other abnormalities. Depending on the region under study and the clinical indication, the exam may be performed with or without contrast.<\/span><\/p>\n

There are several types of MRA, depending on the region of the body being evaluated:<\/span><\/p>\n

Cerebral MRA<\/span><\/h3>\n

Detailed study of intracranial vessels. Indicated in cases of stroke, aneurysms or arteriovenous malformations.<\/span><\/p>\n

Carotid and vertebral MRA<\/span><\/h3>\n

Assessment of the neck arteries that supply the brain. Indicated in stroke prevention or evaluation of stenoses.<\/span><\/p>\n

Thoracic and aortic MRA<\/span><\/h3>\n

Analysis of the aorta and thoracic vessels. Indicated in aneurysms, dissections and surgical planning.<\/span><\/p>\n

Abdominal and renal MRA<\/span><\/h3>\n

Study of the renal, hepatic, mesenteric arteries or the abdominal aorta.<\/span><\/p>\n

Lower limb MRA<\/span><\/h3>\n

Used in the assessment of peripheral arterial disease (e.g., claudication, ischemia).<\/span><\/p>\n

Venous MRA<\/span><\/h3>\n

Assessment of the veins (less common than arterial studies). It can be used to investigate deep vein thrombosis or compressive syndromes.<\/span><\/p>\n

What is the price of a MR Angiography?<\/span><\/h2>\n

The price of Magnetic Resonance Angiography is <\/span>\u20ac360<\/b> when performed <\/span>on a private basis. <\/b>However, MRI exams can also be performed through several <\/span>agreements<\/b>, including:<\/span><\/p>\n
