Preparation instructions for magnetic resonance imaging (MRI)

MRI is a complex, but safe and effective diagnostic method that is not associated with ionizing radiation and the introduction of radioactive substances.

MRI allows you to get clear images of internal organs, helps to establish a diagnosis and prescribe the appropriate treatment.

The Department of Magnetic Resonance Imaging and Ultrasound Diagnostics of the NMRC for Hematology is equipped with high-tech equipment. The team includes candidates of medical sciences and doctors of the highest qualification category, who use unique and innovative methods in examining patients with hemoblastosis, hematopoietic depression, and orphan diseases.

Preparation instructions:

Usually, no special preparation for the study is required and there are no restrictions on food intake.

Patients who have previously worked in mechanical shops or in conditions associated with a high concentration of metal particles in the air should be examined by an optometrist to detect and remove hazardous particles.

With an MRI examination of the abdominal cavity and pelvic organs, it is recommended to exclude gas-forming products (black bread, legumes, etc.) from food for three days before the examination.

Before starting the examination

Tell your doctor if you have artificial pacemakers, prosthetic heart valves, artificial joints, braces, filters, and other medical devices made of metal inside of your body.
Tell your doctor if you have had previous operations on the brain, heart, or other organs.
Tell your doctor if you have any non-medical metal objects (shards, shavings, etc.) in your body.
Tell your doctor if you have epilepsy, convulsive seizures, or have any history of loss of consciousness.
Tell your doctor if you are pregnant.
Remove all items containing metal (watches, jewelry, hair clips, dentures, glasses, hearing aids).
Remove any clothing containing metal (hooks, buttons, clasps, zippers, buckles, shoes with metal plates, etc.).
Remove all metal objects from your pockets (keys, coins, etc.), magnetic media (credit cards, etc.).
Wash off cosmetics containing metal particles (waterproof mascara, etc.).

Metal teeth usually do not affect image quality.

Examination progress

The study will take at least 30-40 minutes.

You will be asked to lie down on a table and placed inside of a large pipe (magnet tunnel). During the entire examination, the doctor will monitor you via a TV camera. If the need arises, you can contact him using a special device.

Your objective is to remain motionless throughout the entire study. The quality of the resulting images depends on this.

During the examination, a rhythmic knock associated with the normal operation of the device will be heard. It may be necessary to introduce a contrast agent in the course of the procedure. This is necessary in order to "highlight" areas of interest to the doctor. MRI contrast media are gadolinium-based compounds that are administered intravenously in a small volume (5–20 ml). Usually this procedure is not accompanied by any discomfort or adverse reactions.
