Magnetic resonance imaging (MRI) of vessels - is one of the most informative diagnostic methods, which makes it possible to obtain clear images of the arteries, veins and capillaries.survey vessels by means of a tomograph, whose magnetic field strength is at least 0.3 Tesla.

MRI brain, spine, neck and other body parts is prescribed for the diagnosis of the following disease states:

  • vasculitis;
  • aneurysm;
  • atherosclerosis of the arteries;
  • bundle aneurysm;
  • stenosis of blood vessels.

MRI in most cases, is used to visualize the brain blood vessels and the neck, as this procedure is prescribed for the inspection of vessels of the spine.

This procedure makes it possible to examine the vessels of any localization.Made in the images after processing computer are converted into a clear two-or three-dimensional image.MRI vessel neck, head and venous sinuses usually conducted without contrast agent.

Using magnetic resonance imaging vascular doctor may:

  • visualize blood clot;
  • examine individual vessels;
  • locate multiple sclerosis plaques;
  • reveal the presence of damage to the myelin sheath and active inflammatory demyelination;
  • make a qualitative analysis of the blood vessels of the spine, brain, upper and lower extremities, neck and other body parts;
  • obtain detailed images of blood vessels of the head;
  • reveal circulatory disorders and a variety of pathological processes that impede the normal functioning of the vascular system;
  • to assess the exact size of foci of vascular lesions;
  • get detailed information about the morphology of the blood vessels.

main advantages of MR vessels are:

  • harmlessness of studies;
  • visualization of blood vessels;
  • high resolution;
  • high diagnostic efficiency;
  • painless procedure.

When appointed?

MRI vessels advisable to conduct in the presence of the following factors:

  • tinnitus;
  • persistent dizziness;
  • presence of thrombosis sinuses of the brain;
  • chronic headaches to severe intensity;
  • head injuries of varying severity in history;
  • ischemic disease;
  • presence of vegetative-vascular dystonia.

especially irreplaceable magnetic resonance imaging of vessels in those cases where other studies have helped to establish the cause and origin of frequent headaches.In addition, this procedure is given to patients who are preparing to step on the cardiovascular system.

vascular MRI may reveal:

  • aneurysm cavernomas, malformations, congenital and acquired vascular malformations;
  • tumor formation;
  • coronary disease and atherosclerosis;
  • thromboangiitis obliterans;
  • post-thrombotic syndrome;
  • presence of emboli, clots and vascular stenosis;
  • varicose veins;
  • angiopathy different origin;
  • separation walls of the coronary arteries and the aorta;
  • phlebitis and thrombophlebitis.

How to prepare?

Specific training magnetic resonance imaging of the blood vessels of the patient requires.If the research carried out by contrast, the procedure before the nurse enters a patient a contrast agent.

Contraindications Absolute contraindications to MRI vessels are:

  • pacemaker;
  • presence of clips in the vessels of the head;
  • availability of electronic, metal and ferromagnetic implants.

Relative contraindications to magnetic resonance imaging of vessels are considered the first trimester of pregnancy and claustrophobia.
