MRI (magnetic resonance imaging) is a scanning technique for creating detailed images of the internal structure of the body. The CT scanner uses a strong magnetic field and radio waves to generate images. This allows you to detail areas that are difficult to visualize using X-rays, computed tomography, or ultrasound. For example, an MRI scan can help doctors see the inside of joints, cartilage, ligaments, muscles, and tendons, making it useful for detecting various sports injuries. The price of magnetic resonance imaging is slightly higher than X-rays and CT scans, but this method allows for a more accurate diagnosis.
Magnetic resonance imaging is also used to diagnose various soft tissue disorders, including:
- strokes;
- tumors;
- aneurysms;
- spinal cord injuries;
- multiple sclerosis;
- problems with the visual system or the inner ear.
MRI is widely used in research abroad to determine the structure and function of the brain.
Magnetic resonance imaging procedure
After recording for an MRI scan, the patient is assigned the day and hour of the procedure. During the session, the patient is asked to lie down on a movable table that will slide into a doughnut-shaped hole to scan a specific part of the body. The patient does not feel a magnetic field or radio waves, so the procedure is painless, but quite noisy. The constant change in the direction of magnetic fields causes loud clicks or beeps, so ear protection is required during scanning. The scan time may take from 30 to 60 minutes.
An MRI scan with contrast may be recommended for some people. Before diagnosis, they are injected intravenously with liquid dye, which can make the contours of problem areas more visible in the image. The price of an MRI scan with contrast may differ from the standard diagnosis.
It is very important not to move during the procedure, as active movement can blur the images. Therefore, small children, as well as people who suffer from claustrophobia, are prescribed a soothing medicine. It helps them relax or fall asleep. The price of magnetic resonance imaging in this case should also be specified in advance. Some clinics have an open MRI machine, which is more suitable for people with claustrophobia.
The safety of MRI
The fact is that MRI is the only imaging method that does not use ionizing radiation. Magnetic resonance imaging is even prescribed to diagnose the fetus during pregnancy. At the same time, no adverse effects on the fetus were detected.
However, since strong magnets are used during the scan, any kind of metal implant is dangerous. The implant can move or heat up in a magnetic field. Therefore, it is necessary to inform the doctor about the presence of a pacemaker, artificial joint, heart valve, cochlear prosthesis or metal plates, screws or rods.
The price of an MRI scan for a specific area of the body can be found on the website of the selected clinic or by phone.
