Magnetic Resonance Imaging (MRI)
Magnetic Resonance Imaging (MRI or MR) is a relatively new technique which uses powerful magnetic fields and radio waves to create detailed images of the body. More advanced techniques have been or are being developed, including MR Angiography (study of blood vessels), functional MR (fMRI) (study of activity of certain organs, such as the brain), MR Spectroscopy (MRS) (obtaining biochemical information from tissues), and cine MR (to study moving organs, such as the heart).
