A Magnetic Resonance Imaging (MRI) scan is an imaging test that uses a magnet, radio waves and a computer to produce detailed pictures of organs and structures inside the body. It’s used to diagnose medical conditions such as tumors, strokes and spinal cord injuries. It also can be used to evaluate other problems such as infections or bleeding in the brain.
The MRI machine is completely enclosed and you lie on a table that slides into the center of the machine. Once you’re inside, the door closes behind you. You may hear loud tapping or buzzing sounds as the machine creates images of your body with magnetic fields and pulses of radio waves. These sounds are normal and should not alarm you. However, if they cause concern for your well-being, let your doctor know so he or she can help alleviate any anxiety that may arise from these sounds.
The MRI image will show doctors whether there is any damage to your brain tissue or other parts of your body. This helps them determine how severe your trigeminal neuralgia is and which treatments are most effective for treating it.
