Welcome to Wikipedia, and thank you for your contributions. One of the core policies of Wikipedia is that articles should always be written from a neutral point of view. A contribution you made to Magnetic resonance imaging appears to carry a non-neutral point of view, and your edit may have been changed or reverted to correct the problem. Please remember to observe our core policies. Thank you. Abecedare (talk) 21:19, 28 April 2009 (UTC)

Please do not add commentary or your own personal analysis to Wikipedia articles, as you did to Magnetic resonance imaging. Doing so violates Wikipedia's neutral point of view policy and breaches the formal tone expected in an encyclopedia. Thank you. Abecedare (talk) 21:49, 28 April 2009 (UTC)

Please stop. If you continue to violate Wikipedia's neutral point of view policy by adding commentary and your personal analysis into articles, as you did to Magnetic resonance imaging, you will be blocked from editing Wikipedia. Abecedare (talk) 22:06, 28 April 2009 (UTC)

You currently appear to be engaged in an edit war according to the reverts you have made on Magnetic resonance imaging. Note that the three-revert rule prohibits making more than three reversions on a single page within a 24 hour period. Additionally, users who perform a large number of reversions in content disputes may be blocked for edit warring, even if they do not technically violate the three-revert rule. If you continue, you may be blocked from editing. Please do not repeatedly revert edits, but use the talk page to work towards wording and content that gains a consensus among editors. If necessary, pursue dispute resolution. Abecedare (talk) 22:07, 28 April 2009 (UTC) Must reach consensus

Over the past couple of years, I have made various attempts to make the section on MRI accord with the truth of history. When I make postings, the entire article is automatically reverted, even though each statement is validly footnoted. I would like to reach a consensus that gives Raymond V. Damadian's contributions their fair place. Here are two quotes from respected textbooks that I hope make the point:

“The initial concept for the medical application of NMR, as it was then called, originated with the discovery by Raymond Damadian in 1971 that certain mouse tumours displayed elevated relaxation times compared with normal tissues in vitro. This exciting discovery opened the door for a complete new way of imaging the human body where the potential contrast between tissues and disease was many times greater than that offered by X-ray technology and ultrasound …. NMR developed into a laboratory spectroscopic technique capable of examining the molecular structure of compounds, until Damadian’s ground-breaking discovery in 1971.” MRI from Picture to Proton, Cambridge University Press, 2003

Making Modern Science, A Historical Review, The University of Chicago Press, 2005“By the final few decades of the twentieth century, medical practitioners were exploiting developments in nuclear physics to provide a range of new ways of peering inside the human body …. Another technique developed during the 1970s was MRI (magnetic resonance imaging). The technique was initially developed by Raymond Damadian (1936 -), working at the Downstate Medical Center in New York, making use of the fact that different atomic nuclei emit radio waves of predictable frequencies when exposed to a magnetic field. Damadian noted that tumorous cells emitted signals different from those emitted by healthy tissue and used this as the basis for a new technique for identifying cancers. Damadian and his fellow workers produced the first MRI scan of the human body in 1977.” Making Modern Science, A Historical Review, The University of Chicago Press, 2005.

In addition, the footnotes on the changes I made are here for examination. Magnetic resonance imaging is a relatively new technology. It began in 1969 when Raymond V. Damadian, a medical doctor who grew up in Forest Hills, New York, proposed scanning the human body by NMR (MR). He conducted experiments on cancer tissue and normal tissues in rats and discovered the marked differences in the T1 and T2 relaxation times between cancer tissue and normal tissues. Damadian reported his findings in Science. The signals he discovered are the source of every MRI image; they account for the pixel brightness. The first MR image was published in 1973. Damadian built the first whole-body MR scanner at New York's Downstate Medical Center, with the help of two postdoctoral fellows, and achieved the first scan of a live human, a cross section of the human chest.
