One frame of an MRI scan of the head showing the eyes and brain A magnetic resonance imaging instrument ( MRI scanner ), or "nuclear magnetic resonance ( NMR ) imaging" scanner as it was originally known, uses powerful magnets to polarize and excite hydrogen nuclei (i.e., single protons ) of water molecules in human tissue, producing a ...
Traditional MRI generates poor images of lung tissue because there are fewer water molecules with protons that can be excited by the magnetic field. Using hyperpolarized gas an MRI scan can identify ventilation defects in the lungs. Before the scan, a patient is asked to inhale hyperpolarized xenon mixed with a buffer gas of helium or nitrogen ...
I acknowledge that getting this scan is a major expense, and a privilege, as their scan prices start at $1,000. I should also note that not all experts think a full-body MRI scan is totally necessary.

The subject drinks 1.5 litres of oral contrast (3% mannitol) [3] over 30 to 45 minutes before the scan. After that venous access is obtained and Buscopan (hyoscine butylbromide) is given to reduce the gastrointestinal tract movement, thus reducing motion artifact on MRI scan. [4]
All patients are reviewed for contraindications prior to MRI scanning. Medical devices and implants are categorized as MR Safe, MR Conditional or MR Unsafe: [6] MR-Safe – The device or implant is completely non-magnetic, non-electrically conductive, and non-RF reactive, eliminating all of the primary potential threats during an MRI procedure.
