In the section that relates the Ernst angle to MRI, one sentence reads "In MRI, there is typically just one resonance being observed - H2O -...". Would this be more accurate if H20 was changed to 1H? 137.197.233.12 (talk) 21:12, 6 March 2012 (UTC)Reply

No. Most protons, except water (and sugar, alcohol, metabolites) in the body are bound to macromolecules (proteins, tissue, etc) or highly viscous substances (fat), and have a short transverse relaxation time. They do not show up in the standard imaging sequences. (it is of course possible to observe them!) --129.13.72.198 (talk) 05:21, 24 October 2016 (UTC)Reply

... is not the same allover the body! T1 is very often the contrast in MRI!--129.13.72.198 (talk) 05:21, 24 October 2016 (UTC)Reply
