MRI stands for Magnetic Resonance Imaging. MRI is considered to be the gold standard of imaging for many cases and continues to evolve. An MRI scanner is a very powerful magnet that is up to 50000 times stronger than the earth's magnetic field. We image hydrogen protons because the body is made up of 90% water. When the body is exposed to a magnetic field in the MRI environment, the hydrogen protons align to the field. With the use of radiofrequency waves, the hydrogen protons are knocked off their axis and as they realign with the magnetic field they give off a signal. The signal is received by the specific coil that is placed over the area to be scanned, and with computer technology it is transformed into a very detailed image. MRI is a safe and painless exam that does not use X-rays or ionizing radiation.
