Scientists at Pacific Northwest National Laboratory hope slow magic-angle spinning magnetic resonance spectroscopy or "slow MAS" can be used to see the physiology of internal organs in real time.

Document Title: Slow MAS
Category: Health-Related Research and Technologies
Media Type: Graphics
Date of Image/Photo: Early 2005
Background: This story is all spin. A mouse in a form-fitted Plexiglas tube performs the honors, spinning like an old phonograph record, at a leisurely one to three revolutions a second. The mouse chamber is tilted just so inside a magnetic field being pelted with radio waves. The tiny rodent is put under and is no worse for the wear. This technique, called slow magic-angle spinning magnetic resonance spectroscopy or "slow MAS," has provided researchers a new glimpse inside living tissue and cells that other biomedical imaging methods cannot render. The difference between conventional nuclear magnetic resonance, or NMR, and slow MAS is akin to a near-sighted person looking at a mountain range without her glasses one moment and with glasses the next. Previously indistinguishable peaks and valleys appear, the peaks representing previously unseen biochemical compounds as they appear in living tissues.
