Original sentence: In the late 1970s, physicists Peter Mansfield and Paul Lauterbur, developed MRI-related techniques, like the echo-planar imaging (EPI) technique.Mansfield and Lauterbur were awarded the 2003 Nobel Prize in Physiology or Medicine for their "discoveries concerning magnetic resonance imaging"
Edited sentence: Damadian discovered that tumors and normal tissue can be distinguished in vivo by nuclear magnetic resonance (NMR) because of their prolonged relaxation times, both T1 (spin-lattice relaxation) or T2 (spin-spin relaxation).Damadian invented an apparatus and method to use NMR safely and accurately to scan the human body, a method now well known as magnetic resonance imaging (MRI).Damadian was the first to perform a full body scan of a human being in 1977 to diagnose cancer.Damadian's research into sodium and potassium in living cells led him to his first experiments with nuclear magnetic resonance (NMR) which caused him to first propose the MR body scanner in 1969.Raymond Vahan Damadian (born March 16, 1936) is an American physician, medical practitioner, and inventor of the first MR (Magnetic Resonance) Scanning Machine
