How does an MRI scanner work?
The human body is made up of mostly water (H2O). Water molecules contain hydrogen nuclei (protons), which align in a magnetic field. An MRI scanner applies a very powerful magnetic field during the scanning process (roughly a thousand times the strength of a fridge magnet) and aligns these protons in the body.
What shows up on an MRI?
An MRI is a highly technical and informative way of creating images of the human body. The created images are very useful for medical professionals to detect and subsequently diagnose and treat, structural abnormalities of the body’s organs, soft tissues, muscles, ligaments and other structures inside the body.
