What is a MRI Scanner, and how is it used clinically?
MRI stands for magnetic resonance imaging. It is an extremely powerful machine that is an invaluable diagnostic tool in the medical industry. An MRI machine uses a string magnetic field to produce high quality images in multiple planes/directions. These images are created using superconducting magnets and pulsing radio waves. MRI scans differ from x-rays in that they us non ionising radiation, whereas x-rays use radiation, which in high doses can be much more harmful. (more…)
