The story of the MRI (Magnetic Resonance Imaging) machine, especially as it is used today for medical purposes, is a tale that weaves together the contributions of many great scientific minds across two generations.<\/p>\n

It began in 1882 when Nikola Tesla discovered the Rotating Magnetic Field, a fundamental discovery in physics.<\/p>\n

The next significant discoveries came in 1937 from Columbia University Professor Isidor I Rabi, and in 1946, from Felix Bloch at Stanford, and Edward Mills Purcell at the Massachusetts Institute of Technology, who discovered and demonstrated the quantum phenomenon known as nuclear magnetic resonance (NMR).<\/p>\n

In simple words, NMR allowed scientist to see the structure of a molecule in detail. All three received the Nobel Prize for their efforts.<\/p>\n

Now, the work by Rabi, Bloch and Purcell laid the foundations for the second generation of scientists in the 1970s, who discovered how to create images from the NMR signal.<\/p>\n

Up until the 1970s, MRI technology was only being used for chemical and physical analysis.\u00a0Enter Raymond Damadian, a doctor, who wondered if the same methods could be used on living organisms to detect disease.<\/p>\n

In 1971, he concluded that since cancerous tissue contained more water than healthy tissue, it could be detected by scanners that bathed a part of the human body in radio waves and measured the emissions from the local hydrogen atoms. Damadian then began building a full body scanner called the Indomitable.<\/p>\n

Around the same time, a chemist named Paul Lauterbur, working at the State University of New York, published the first true MR image in\u00a0Nature<\/em>\u00a0in March, 1973. He was the first to realize that a gradient magnetic field would allow observers to take two-dimensional images of an object, which could then be stacked to create a three-dimensional view.<\/p>\n

Meanwhile, in England, physicist Peter Mansfield was\u00a0tackling the question of time, trying to find a way to complete\u00a0scans in minutes rather than hours. By adopting a new\u00a0technique he called \u201cline scan imaging\u201d, Mansfield was able\u00a0to capture\u00a0images of his grad student Andrew Maudsley\u2019s\u00a0finger\u00a0in only 15\u201323 minutes per section, marking the first\u00a0time that a human body part had been successfully scanned\u00a0with NMR technology.<\/p>\n

By mid-summer, 1977, Damadian completed the Indomitable and the first whole-body MR images were being produced, including the famous one shown below of his assistant’s chest. However, his method of producing scans was considered too slow and clumsy, and was abandoned in favour of Lauterbur and Mansfield\u2019s methods.<\/span><\/p>\n

Primary credit (and the Nobel Prize) for MR imaging\u00a0was awarded to\u00a0Sir Peter Mansfield\u00a0and\u00a0Paul Lauterbur. Damadian considered it a personal affront that he was excluded and placed full-page ads in several large world newspapers urging the Nobel committee to change its mind. The decision however stood.<\/p>\n

Currently, the 3T MRI is the most advanced MRI machine available \u2013 the same one that we have at Star Imaging.<\/p>\n
