The principle of the tomograph is based on the change in the responses of hydrogen atoms under the influence of a magnetic field. The device reads them and sends them to the computer monitor in the form of achromatic images. Using computer modeling programs, it is possible to create a 3D model of the heart in real time to identify pathological changes and their localization.
The patient is prescribed MRI of the coronary arteries and heart in the following cases:
To obtain more accurate data, MRI with contrast is used. The technique is based on the use of a contrast agent with gadolinium. It is injected into the patient, and during scanning, pathological areas on the image are colored. This allows you to identify the smallest violations, including small tumors, up to several millimeters in diameter.
MRI with contrast is not performed in cases of renal and hepatic insufficiency, as well as in cases of allergic reactions to the drugs used.
Contraindications to MRI diagnostics will be:
Patients with acute claustrophobia are recommended to take sedative medications before the procedure.

MRI of the heart and coronary vessels: what the study shows
According to WHO statistics, up to 10% of all heart diseases occur in people under 40 years of age. With age, the number of diseases associated with disorders in the cardiovascular system increases. The situation is worsened by the fact that in the early stages of heart and vascular pathology they do not manifest themselves in any way or are accompanied by non-specific symptoms. This is why accurate diagnostics are so important for the treatment of these diseases.
MRI of the heart and coronary vessels allows you to obtain detailed, layered images of the area being examined. Thanks to this, the doctor can:
Conducting MRI helps in preoperative preparation, treatment planning for hypertrophic cardiomyopathy, and detection of neoplasms.
