Magnetic resonance imaging of the heart - it is a high-tech, safe and informative method of diagnostics of cardiovascular system without the use of ionizing radiation.MRI allows you to take pictures with the wide field of view in any plane, to assess myocardial contractile function and perfusion.In addition, research is used to study the anatomical structures of the heart and helps to accurately measure the volume of cavities of the heart and blood flow through the valves, and perform non-invasive angiography.

Diagnostics is performed as follows: the patient is placed on a non-metallic narrow scanner platform under his head enclose the pillow, and his hands are fixed along the body.platform is then introduced into the scanner, and then start to irradiate radio waves thorax.The resulting image is projected on the screen sections and recorded on tape or video tape for long term storage.During the procedure the patient

is required to lie motionless, and in some cases, periodically hold their breath in order to reduce image blur.The survey takes about 60 minutes.After the procedure the patient no restrictions are imposed.

often on the recommendation of a doctor-radiologist examinee is administered a special contrast agent that enhances the outgoing return signal from the arteries or veins.The drug is administered intravenously, and allows you to identify heart disease and coronary blood vessels that supply the body with blood.

When he appointed?

Indications for MRI of the heart are:

  • Diagnostics noncoronary myocardial pathology (systemic disease, cardiomyopathy, myocardial lesions of various etiologies).
  • acquired heart defects.
  • Diagnostics heart tumors (malignant and benign) and the surrounding tissue.
  • major diseases of the coronary vessels.
  • Congenital heart defects.
  • pericardial diseases of different etiologies.
  • Coronary heart disease (CHD), the discovery of "fresh" ischemic changes, the assessment of myocardial viability by means of early and delayed contrast enhancement.
  • Abnormalities of the heart valves (assessment of the degree of stenosis and regurgitation, and other blood parameters).


cardiac MRI is contraindicated in the presence of: hemostatic clips in the skull cavity (under the influence of the field imager clips can shift), intracardiac catheters (they can be heated under the influence of a magnetic field), implantable defibrillators and pacemakers (possible malfunction of the device, its displacement, the heating of the electrodes).Also, MRI is done to patients who entered Foley catheter, a hearing aid, a cochlear implant (disrupted devices), embolization coils, endokardinalnye electrodes (possibly heated), valve prostheses (survey safely, but prostheses may distort the MRI readings) or electrodes for ECG.

How to prepare?

Before the procedure is necessary to take off anything containing metal (jewelry, buckles, watches, etc.).Also, the physician should make sure that the patient is not implanted metal structures (joint prostheses, pacemakers, clips, needles, prosthetic heart valves, etc.) to which the magnetic scanner can respond.

patient should be put on a cotton bathrobe.To protect your hearing from noise emanating from the gradient coils system, you should use earplugs or special headphones.

If the examinee suffers from claustrophobia or hurt him to lie on his back throughout the diagnosis, the doctor may prescribe a sedative or anesthetic to the patient underwent the procedure easier.
