MRI is a medical examination that uses strong magnets and radio waves to create accurate images of the inner body parts, such as the brain, bones and organs.
It is characterized by that it does not use radiation, and helps doctors diagnose diseases and know what is happening inside the body, without the need for surgery.
How does MRI work?
MRI is dependent on the magnetic properties of hydrogen atoms present in the water inside the body’s tissues, and here the patient is inside a device that contains a very strong magnet, the hydrogen atoms in the body are rearranged under the influence of this magnetic field.
Radical waves are sent to stimulate these atoms, and when the atoms return to normal, signals are made to be taken and converted into pictures using the computer.
In the images, accurate details show that organs such as the brain, spine, heart, joints, liver, and others can be examined.
MRI features
MRI is characterized by high accuracy in soft tissue imaging.
It is considered the best for brain photography, spinal cord, muscles, ligaments, and internal organs.
Also, it does not use ionizing radiation, unlike X -rays or CT scans (CT), the patient is not exposed to the risk of radiation, and thus it is safe for pregnant women.
It does not need surgical intervention, so the patient does not feel pain while filming.
It also allows photography from multiple angles, as the same member can be photographed from different corners and directions, which gives a comprehensive vision of the pathological condition.
It is characterized by accurately in detecting diseases, especially in the discovery of tumors, clots, brain infections, spine problems, and ligament rupture.
It can detect diseases before the appearance of clear symptoms, which helps in early treatment.
When do we resort to MRI?
MRI (MRI) is used when the doctor needs an accurate vision of soft tissue details inside the body, which does not appear clearly in X -rays or CT scans (CT), and among the most prominent cases.
MRI and disease exploration
Through magnetic resonance imaging, heart disease, nervous system, digestive system and bone problems can be explored.
