Magnetic resonance imaging (MRI) is a way to map out structures inside the body without using radiation. It helps your doctor see many things, like your:
- Blood vessels.
- Ligaments.
- Muscles.
- Nerves.
- Organs.
- Skeletal system.
Luminis Health Imaging uses the latest MRI technology to maximize your comfort as we create crisp, clear images.
How Do MRIs Work?
You may have heard that water makes up about 60% of our bodies. What you may not know is the hydrogen atoms in water respond to electromagnetic energy around us. MRIs rely on this cool fact.
MRIs use a magnetic field to align hydrogen atoms in the body. Then, the machine pulses out electromagnetic radio waves. This causes the atoms to spin.
When the technologist turns off the radio frequency waves, the atoms realign. As structures in the body have different amounts of water, they release different amounts of energy during this process. The MRI sensor captures the energy waves to create images.
MRI images not only show the various tissues of the body, but they can also highlight inflamed or cancerous areas. These have different water content than surrounding tissues.
