A magnetic resonance imaging (MRI) scan of the brain uses powerful magnets and radio waves to produce a detailed picture of the brain and nerve tissues.

Magnetic resonance imaging, or MRI, is a noninvasive device used for evaluation, assessment and diagnosis of conditions, diseases and injuries. An MRI generates images of the brain and spine from multiple angles, and it also can provide pictures of blood vessels, tissues and organs.

Magnetic resonance imaging is a test that uses a computer to produce very detailed pictures of body structure to help diagnose various diseases and medical conditions. MRIs are not X-rays and do not use radiation. A serum creatinine is a lab test that may be done to measure kidney function before an MRI is performed.
