Magnetic resonance angiography (MRA) of cerebral vessels
Magnetic resonance angiography (MRA) of cerebral vessels is one of the most promising and rapidly improving methods of modern diagnostics of the vascular bed, which does not require direct puncture of the artery.
With magnetic resonance angiography (MRI) of the vessels of the brain, the doctor gets the opportunity to investigate the structural and pathological changes in the vascular bed of the brain tissue, to evaluate the physicochemical, pathophysiological processes of the entire brain and its membranes as a whole or its structures.
Magnetic resonance angiography (MRI) procedureof of the brain vessels.
Magnetic resonance angiography (MRA) of cerebral vessels allows you to obtain a series of thin sections, build a three-dimensional reconstruction of the vasculature in the area under study, and isolate individual nerve trunks and vessels passing in the plane of a particular part of the human brain.
Such reconstruction on magnetic resonance angiography (MRI) of the cerebral vessels provides invaluable assistance to the doctor in planning treatment and for subsequent monitoring during the patient's therapy.
Early diagnosis using magnetic resonance angiography (MRI) of the vessels of the brain allows timely treatment of the disease. The ability, using magnetic resonance angiography (MRI) of cerebral vessels, to simultaneously demonstrate the vessel itself and soft tissues around it over a large area without introducing contrast agents into the lumen of the vessel and without using ionizing radiation (X-ray), to determine the localization and size of aneurysms, hematomas, blood clots, and pathological vascular anastomoses.
Currently, magnetic resonance angiography (MRA) of cerebral vessels has come out on top in the diagnosis of most vascular diseases of the brain, relegating methods such as radiography and computed tomography (CT) to the background.
In what cases can a Magnetic resonance angiography (MRA) of cerebral vessels be prescribed:
- Arteriovenous malformations of the brain
- Cerebral and spinal adhesive arachnoiditis
- Headache, migraine
- Increased intracranial pressure and hydrocephalus
- Ischemic brain disease
- Ischemic stroke, cerebral ischemia
- Nosebleeds (Epistaxis)
- Parkinson's disease
- Pituitary microadenoma, macroadenoma and nonfunctioning adenomas (NFPAs), hyperprolactinemia syndrome
- Saccular aneurysm and subarachnoid hemorrhage
- Somatoform autonomic dysfunction
- Traumatic brain injury (concussion, contusion, brain hemorrhage, axonal shearing lesions)
- Vertebrobasilar insufficiency (VBI) with vertigo symptom
Our patients are invited to undergo MRI angiography on an apparatus with a magnetic field of 3.0 T (Tesla). It is also possible to conduct MRI with intravenous contrast (Omniscan contrast) to increase the visual difference between healthy tissue and tumor. Weight limitation (for a patient with a large weight) during magnetic resonance imaging (MRI) - up to 200 kg.
