[edit] Early life

Damadian was born in New York. He is of Melville, New York, a scientist of Armenian descent, who earned his BS in mathematics from the University of Wisconsin-Madison in 1956, and an M.D. degree from the Albert Einstein College of Medicine in New York City in 1960.

[edit] Work on MRI

In a 1971 paper, he reported that tumors and normal tissue responded differently to nuclear magnetic resonance ("NMR") in the journal Science. He suggested that these differences could be used to diagnose cancer, though later research would find that these differences, while real, are too variable for diagnostic purposes. Additionally, some of his initial methods would turn out to be flawed.[1] Nonetheless, in 1974, he patented the design and use of NMR[2] for detecting cancer. As the[3] notes, "The patent included the idea of using NMR to "scan" the human body to locate cancerous tissue". However, it did not describe a method for generating pictures from such a scan or precisely how such a scan might be done.

In the 1950s, Herman Carr[4] using gradients to create a one-dimensional MR image. Prompted by Damadian's report on the potential medical uses of NMR, Paul Lauterbur and Peter Mansfield expanded on Carr's technique to generate the first 2D and 3D MRI images. While Lauterbur and Mansfield focused on animals and human limbs, it was Damadian who produced the first full magnetic resonance imaging ("MRI") scan of the human body, albeit using a "focused field" technique that differs from conventional imaging.

In 1978, Damadian formed his own company, FONAR, for the production of MRI scanners, and in 1980, he produced the first commercial one. Unfortunately for Damadian, his "focused field" technology proved less effective than Carr's gradient approach. His scanner, named "Indomitable", failed to sell. FONAR eventually abandoned Damadian's technique in favour of the methods adopted by Lauterbur and Mansfield...[5] Damadian and FONAR aggressively enforced the royalties on patents held by Damadian.[6]

Damadian later collaborated with Wilson Greatbatch, one early developer of the implantable pacemaker, to develop a MRI-compatible pacemaker.

[edit] Recognition

Damadian received a National Medal of Technology in 1988 and was inducted in the National Inventors Hall of Fame in 1989. In 2001, the Lemelson-MIT program bestowed its Lifetime Achievement Award on Damadian as "the man who invented the MRI scanner".[7] The Franklin Institute in Philadelphia gave its recognition of Damadian's work on MRI with the Bower Award in Business Leadership. He was also named Knights of Vartan 2003 "Man of the Year".

In recording the history of MRI, Mattson and Simon (1996) credit Damadian with describing the concept of whole-body NMR scanning, as well as discovering the NMR tissue relaxation differences that made this feasible.

[edit] Nobel Prize controversy

In 2003, the Nobel Prize in Physiology or Medicine was awarded to Paul Lauterbur and Sir Peter Mansfield for their discoveries related to MRI. Although Nobel rules allow for the award to be shared with a third party, Damadian was not given the prize.

Between October and November 2003 Damadian took out large, expensive advertisements in The New York Times and The Washington Post protesting his exclusion with the headline "The Shameful Wrong That Must Be Righted".[8] Damadian suggested that Lauterbur and Mansfield should have rejected the Nobel Prize unless Damadian was given joint recognition. Supporting Damadian were various MRI experts including John Throck Watson, Eugene Feigelson, V. Adrian Parsegian, David D. Stark and James Mattson. New York Times columnist Horace Freeland Judson criticised this behavior, noting that there is "no Nobel Prize for whining"[9]

Others point out that while Damadian had hypothesized that NMR relaxation times might be used to detect cancer, he did not develop (nor did he suggest) the current way of creating images. Since the Nobel Prize was awarded to Paul Lauterbur and Sir Peter Mansfield for the development of Nuclear Magnetic Resonance Imaging, Damadian's exclusion makes more sense.

Damadian is a controversial figure in NMR circles, not least for his exuberant behavior at conferences...[10] He is also fundamentalist Christian and a young earth creationist[11] and a member of the "Technical Advisory Board" of the Institute for Creation Research.[12] Philosopher Michael Ruse writing for the Metanexus Institute suggested that Damadian might have been denied a Nobel prize because of his creationist views, saying "I cringe at the thought that Raymond Damadian was refused his just honor because of his religious beliefs. Having silly ideas in one field is no good reason to deny merit for great ideas in another field. Apart from the fact that this time the Creation Scientists will think that there is good reason to think that they are the objects of unfair treatment at the hands of the scientific community.",[13] a point that has been picked up by creationists such as Carl Wieland of Answers in Genesis who cite it as an example of anti-creationist bias in science.[14] Others consider the claim to be mere speculation.[15]
