Magnetic resonance imaging (MRI)

Magnetic resonance imaging is based on the magnetic behaviour of hydrogen atoms in human tissues when they are placed in a magnetic field and excited by radio frequency pulses. After they are excited, the hydrogen atoms return to their normal state by emitting energy that is monitored.
 
This process is characterized by relaxation times, which reflect the chemical and physical properties of tissues (such as temperature and flow) and that contain a lot of information which cannot be obtained by any other imaging modality using ionizing radiation (x-rays). In medical diagnostics, the main uses for the MRI are to study the soft tissues of the central nervous system, spine, extremities, bones, and joints.
 
MRI procedures include:
  • abdomen
  • breast
  • cardiac
  • chest
  • extremities
  • head/neck
  • joints
  • pelvis
  • spine
