Magnetic resonance imaging

Magnetic resonance imaging is a non-invasive imaging technique that creates detailed 3D anatomical images. It is often used to detect diseases, diagnose and to review treatment. This is based on an advanced technology that excites and explores the change in the direction of the rotational axis of protons in the water that makes up living tissue.

Thus, the x-ray works to take an MRI image, by placing the patient inside a large magnet and he must be very steady during the imaging process in order not to spoil the image. Contrast factors that often contain a patient’s component can be given intravenously before or during an MRI to increase the speed at which protons adjust to the magnetic field. Therefore, the faster the resets of protons become, the clearer the picture.


Therefore, MRI does not produce radiation from X-rays and computed tomography, except that it uses a strong magnetic field. The magnetic field extends beyond the machine and exerts great forces on iron, some steel, and other magnetic objects. It is strong enough to throw a wheelchair across the room. Patients should notify their physicians of any medical form that prevents their magnetic imaging before performing an MRI.


When performing an MRI scan, consider the following: People who have implants inside their bodies should not have medical equipment, especially iron-containing devices such as pacemakers and vagus nerve stimuli, the implanted heart device, defibrillators, insulin pumps, cochlear implants, and brain stimulants Deep capsules from the capsule endoscopy

All those who have performed these procedures should not enter the MRI machine.

Jewelry should also be removed. In addition, dressing is required if it contains minerals.

The examination takes between 30 – 40 minutes. During the examination, the person being examined is asked not to move, because the movement leads to the formation of an inconspicuous image. The person also feels during the examination, sometimes, a little heat in the examination area, and this is normal. During the examination, the person also hears light roads when the device is shooting. In most places, headphones can be requested if disturbing.
