Magnetic resonance imaging is one of the modern medical imaging methods used all over the world. The way this technology works is based on radio waves and magnetic fields, as it produces detailed images of the various organs and tissues in the body. Since the discovery of this technology, doctors and researchers have continued to develop it. In order to aid medical procedures and areas of research that have led to breakthroughs in medicine and science.
It is a safe and non-invasive examination. It uses the effect of a magnetic field on the human body for a detailed assessment of anatomical structures from head to toe.
When is the examination performed?
such as x-rays, This test is done to check one of the internal organs, The difference between the two tests is the type of organ that can be examined. Whereas an X-ray forms an image of the body’s hard tissues, like bones, In MRI, soft tissues are imaged. This test focuses on imaging the brain, spine, and joints. Such as checking the spine for a herniated disc. It is recommended to use it only when there is no other way to diagnose the problem.
Most imaging devices are large tubular magnets. When you lie in the MRI machine, The magnetic field temporarily affects the water molecules in your body and rearranges them. These radio waves cause ordinary atoms to emit weak signals that are used to create magnetic cross-sectional resonance images — like a slice of bread.
Magnetic resonance imaging (MRI) of the brain and spinal cord
It is the most commonly used imaging test of the brain and spinal cord. It is often used to help diagnose:
- cerebral aneurysm
- Eye and inner ear disorders
- Multiple Sclerosis
- Spinal Cord Disorders
- Brain attack
- traumatic brain injury
