Raymond Damadian

Raymond Vahan Damadian (born March 16, 1936) is an American physician of Armenian descent, medical practitioner, and one of the first people to notice differential NMR relaxation between normal and pathological tissue.
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 NMR-relaxation body scanner in 1969. Damadian observed 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 was the first to perform a full body scan of a human being in 1977 to diagnose cancer. Damadian was among many individuals and research groups working to develop NMR-based methods to generate images of the human body, a method now known as magnetic resonance imaging (MRI).
Damadian has received several prizes. In 2001, the Lemelson-MIT Prize Program bestowed its $100,000 Lifetime Achievement Award on Damadian as "the man who invented the MRI scanner." He went on to collaborate with Wilson Greatbach, one early developer of the implantable pacemaker, to develop an MRI-compatible pacemaker. 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". He received a [[National Medal of Technology]] in 1988 and was inducted in the [[National Inventors Hall of Fame]] in 1989.
Biography.
Early life.
Damadian was born in [[New York City|New York]], to an [[Armenians|Armenian]]-[[French people|French]] family, Vahan and Odette (née Yazedjian). He earned his bachelor's degree 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. He studied the [[violin]] at [[The Juilliard School|Juilliard]] for 8 years, and played in Junior [[Davis Cup]] [[tennis]] competitions.
He met his future wife, Donna Terry, while he had a job as a tennis coach. She invited him to the 1957 [[Billy Graham]] crusade at [[Madison Square Garden]], and he responded to the [[altar call]]. Raymond and Donna married a year after he finished medical school, and they had three children. Raymond says that he first became interested in detecting cancer when, as a boy of 10, he saw his maternal grandmother, with whom he was very close, die painfully of breast cancer.

Damadian's early work on NMR concerned investigating potassium ions inside cells. He found that the potassium relaxation times were much shorter compared with aqueous solutions of potassium ions. This suggested that potassium was not free but complexed to ‘fixed-charge’ counter-ions, as he had previously determined.
He and other researchers independently investigated the signals of 1H NMR in cells, and found that the relaxation times were much shorter than in distilled water. This was consistent with ordering of a large part of the water by [[adsorption]] onto [[macromolecule|macromolecular]] surfaces. Damadian predicted that cancerous cells would have longer relaxation times, both because of the disordering of malignant cells and because of their elevated potassium levels, since the potassium ions would be ‘structure-breaking’ to the ordered water fraction.
In a 1971 paper in the journal "[[Science (journal)|Science]]", [[SUNY Downstate Medical Center]] professor Damadian reported that [[tumor]]s can be detected in vivo by [[nuclear magnetic resonance]] (NMR) because of much longer relaxation times than normal tissue. He suggested that these differences could be used to detect [[cancer]], even in the early stages where it would be most treatable, though later research would find that these differences, while real, are too variable for diagnostic purposes. However, Damadian in his seminal paper claimed only that his method was a "detection" tool, making no claim about being a diagnostic tool, but intended that it would provide a non-invasive way of detecting cancers and monitoring the effectiveness of their therapy.
In 1974, he received the first patent in the field of MRI when he patented the concept of NMR for detecting cancer after filing an application in 1972. As the [[National Science Foundation]] 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. However, Damadian's recognition that NMR relaxation time can be used to distinguish different tissue types and malignant tissue is what gives MRI its contrast to tissue types.
In the 1950s, [[Herman Carr]] reported creating a one-dimensional magnetic resonance (MR) image. Prompted by Damadian's report on the potential medical uses of NMR, [[Paul Lauterbur]] expanded on Carr's technique and developed a way to generate the first MRI images, in 2D and 3D, using gradients. [[Peter Mansfield]] from the [[University of Nottingham]] then developed a mathematical technique that would allow scans to take seconds rather than hours and produce clearer images than Lauterbur had. While Lauterbur and Mansfield focused on animals and human limbs, Damadian built the first full-body MRI machine and produced the first full [[magnetic resonance imaging]] ("MRI") scan of the human body, albeit using a “focused field” technique that differs considerably from modern imaging.
According to a "[[Wall Street Journal]]" article, Damadian's initial methods were flawed for practical use, relying on a point-by-point scan of the entire body and using relaxation rates, which turned out to not be an effective indicator of cancerous tissue. However, the same article pointed out, “Nevertheless, his observation of T1 and T2 differences in cancerous tissue was a Eureka moment for [[Paul Lauterbur]].” Furthermore, Damadian's seminal paper documented in its Table 2 that T1 relaxation times were different, beyond experimental uncertainty, across all his samples over different healthy tissues: rectus muscle, liver, stomach, small intestine, kidney, and brain. This showed the way to accurate imaging of the body's soft tissues for the first time; X-ray imaging was severely deficient for soft tissue analysis because the difference in absorption was so small (<4%). 
So when in the court case [[Fonar v. General Electric]], GE's attorneys made the same claim that relaxations times were also prolonged in non-cancerous tissue, so were not a good diagnostic, Fonar's attorneys responded that it was unfair to punish Damadian because his methods detected even "more" features than he had intended. Indeed, even today, 90% of [[Magnetic resonance imaging#How MRI works|MRI scans]] on patients produce images that are relaxation dependent, either T1- or T2-dependent images.
First human MRI body scan.
On July 3, 1977, the first MRI body exam was performed on a human being (the first human scan was performed by Peter Mansfield's team in Nottingham a year earlier, on fellow author Andrew Maudsley's finger). It took almost five hours to produce one image: a 106-[[voxel]] point-by-point scan of Larry Minkoff's [[thorax]]. The images were rudimentary by modern standards. Damadian, along with colleagues Larry Minkoff and Michael Goldsmith took seven years to reach this point. They named their original machine “Indomitable” to capture the spirit of their struggle to do what many said could not be done, though no systems would ever use Damadian's method. His technique of imaging was never made into a practically usable method and has therefore never been used in MR imaging as we know it today.
His patent followed on the heels of rumors already floating throughout the scientific community of Lauterbur's proposed idea of using NMR "in vivo" (still in the human body, an imaging device). However, in 1969, Damadian had previously proposed NMR as a method for external scanning of internal cancers in the body, i.e. "in vivo":
Though it would later turn out to be irreproducible, in his 1971 "Science" paper, Damadian showed different NMR signals for tumors and different tissue types:
This was clearly influential, as Lauterbur wrote in 1986:
Thus it was the discovery of strongly variant relaxation times that led to Lauterbur's quest to represent these relaxation time differences graphically. Without these differences, unknown until Damadian's work, there would be nothing to make an image with. Hence a book on MRI history, which included chapters on both Damadian and Lauterbur, Chapter 8 entitled, “Raymond V. Damadian: Originator of the Concept of Whole-Body NMR Scanning (MRI) and Discoverer of the NMR Tissue Relaxation Differences That Made It Possible.” The book pointed out the importance of both men:
Damadian's machine is now in the [[Smithsonian Institution]]. As late as 1982, there were a handful of MRI scanners in the entire United States; today there are thousands.
Fonar Corporation.
In 1978, Damadian formed his own company, Fonar (which stood for "Field Focused Nuclear Magnetic Resonance"), for the production of MRI scanners, and in 1980, he produced the first commercial one. Damadian's "focused field" technology proved significantly less efficient and slower than Lauterbur'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. Damadian and Fonar enforced the [[royalties]] on patents held by Damadian. They settled with many large companies, but a [[Fonar v. General Electric|case]] against [[General Electric]] went to the [[United States Court of Appeals for the Federal Circuit|Federal Circuit]], which upheld a $129 million ruling against GE for violation of Damadian's patents. Damadian says that the judgment money has all been put back into Fonar for research and development purposes.
Damadian is the company's largest shareholder, with 8% of stock worth $6.5 million. Despite owning only 8% of the stock, he maintains almost 100% control of the company through a separate class of shares (Class C) that only Damadian controls 2007. Damadian later collaborated with [[Wilson Greatbatch]], one early developer of the implantable [[artificial pacemaker|pacemaker]], to develop an MRI-compatible pacemaker. He invented a stand-up MRI system and has 15 MRI scanning centers across the United States. There are a number of independent MRI centers that use this technology both in the U.S. and around the world. The company conceived and built the world's first Upright Multi-Positional MRI, which was recognized as The Invention of the Year in 2007 by the Intellectual Properties Owners Association Education Foundation.
Creationism.
In the February 4, 2014 [[Bill Nye–Ken Ham debate]], Damadian was one of the scientists who recorded themselves on video professing a belief in [[young Earth creationism]] for [[Answers in Genesis]] president [[Ken Ham]] to cite.
Awards and honors.
Damadian received a [[National Medal of Technology]] in 1988 and was inducted into the [[National Inventors Hall of Fame]] in 1989. His original MRI full-body scanner was given to the [[Smithsonian Institution]] in the 1980s and is now on loan and on display at the National Inventors Hall of Fame in Ohio. In 2001, the [[Lemelson-MIT Prize]] Program bestowed its $100,000 Lifetime Achievement Award on Damadian as "the man who invented the MRI scanner."
The [[Franklin Institute]] in [[Philadelphia, Pennsylvania|Philadelphia]] gave its recognition of Damadian's work on MRI with the [[Bower Award in Business Leadership]]. He was named the [[Knights of Vartan]] 2003 "Man of the Year." In September 2003, he was honored with the Innovation Award in Bioscience from "[[The Economist]]".
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 by up to three recipients, Damadian was not given the prize. The controversy over who played what part in the development of the MRI had gone on for years prior to the Nobel announcement, and many in the scientific community felt that the Nobel had not been awarded for the MRI for so long due to debate over Damadian's role in its development.
Damadian said that credit should go to "me, and then Lauterbur," and Lauterbur felt that only he should get credit. In 1997 the [[United States National Academy of Sciences|National Academy of Sciences]] commissioned a timeline of MRI milestones, and four of the 12 in an initial draft were attributed to Damadian. At the final publication in 2001, longer than any other publication in the series had ever been taken, none of the milestones were attributed to Damadian. The text said that Damadian's methods had "not proved clinically reliable in detecting or diagnosing [[cancer]]." After Damadian's [[lawyer]]s sent the NAS a threatening letter, the text on the NAS website was revised, but not to Damadian's satisfaction. Damadian said in 2002, "If I had not been born, would MRI have existed? I don't think so. If Lauterbur had not been born? I would have gotten there. Eventually."
The "New York Times" wrote:The issue has been the subject of a dispute between Dr. Damadian and Dr. Lauterbur and has been known for years in academic circles, with some fearing that the Nobel committee would steer clear of magnetic resonance imaging altogether because of the Swedes' supposed distaste for controversial discoveries. Dr. Lauterbur, 74, is not in good health, and the committee may have decided that its prize, which cannot be given posthumously, needed to be awarded for the discovery now or never.".
After the announcement of Lauterbur and Mansfield's Nobels, between October and November 2003, an ad hoc group called "The Friends of Raymond Damadian" (formed by Damadian's company FONAR) took out full-page advertisements in "[[The New York Times]]" twice, "[[The Washington Post]]", "[[The Los Angeles Times]]" and one of the largest newspapers in [[Sweden]], "[[Dagens Nyheter]]" protesting his exclusion with the headline "The Shameful Wrong That Must Be Righted" in an attempt to get the Nobel Committee to change its mind and grant him a share of the Prize.
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 Stark and James Mattson. "[[New York Times]]" columnist [[Horace Freeland Judson]] criticised this behavior, noting that there is "no Nobel Prize for whining" and that many deserving candidates who may have had better claims than Damadian, such as [[Lise Meitner]], [[Oswald Avery]] and [[Jocelyn Bell]], had been previously denied a share of the Nobel. However, he had to admit that [[Erwin Chargaff]], whose [[Chargaff's rules|two rules]] were instrumental in the discovery of DNA's structure, was very vocal about his omission, and [[Fred Hoyle]] was irate about [[Jocelyn Bell]]'s exclusion.
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 Lauterbur and Mansfield for the development of Nuclear Magnetic Resonance "Imaging", Damadian's exclusion makes more sense. Some felt that research scientists sided with Lauterbur because he was one of their own, while Damadian was a physician who had profited greatly from his early patents. Charles Springer, an expert in MRI at Oregon Health and Science University, said that if a poll was taken of the academic community, most would agree with the [[Nobel Committee]]'s conclusions. And Mansfield wrote in his autobiography that "the person who really missed out" on winning the prize was [[Erwin Hahn]] for his contribution to the principles of [[spin echoes]].
Chemist [[George Kauffman]] argued that Damadian deserved the Nobel:
Undoubtedly, both Damadian and Lauterbur made major contributions to MRI imaging and scanning. Without Damadian’s relaxation discoveries that showed sharp discrimination between tissues and particularly a serious disease like cancer, there would have been no reason to entertain or even consider a method for displaying the relaxation differences so that they could be visualized as an image. Furthermore, except for the relaxation differences discovered by Damadian, there would be no reason to expect that such an image would show anything, i.e., that any tissue NMR contrast existed with which to make an image.
Science and technology are two distinctly different enterprises. Science is the branch of knowledge dedicated to compiling factual information and understanding natural phenomena. It precedes technology, and technology cannot advance without it. Without science’s new knowledge of natural phenomena, technology’s new methods for exploiting and taking advantage of nature’s secrets cannot be created. The new scientific information is necessarily the first step.
Moreover, there is no doubt that Damadian’s seminal discovery preceded Lauterbur’s developments. 
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.
Damadian himself said, "Before this happened, nobody ever said to me 'They will not give you the Nobel Prize for Medicine because you are a creation scientist'. If people were actively campaigning against me because of that, I never knew it."
