The imaging community often omits the word "nuclear" and attaches the word "imaging" so that NMR becomes MRI. The former change is largely due to public relations concerns, while the latter refers to the imaging. For convenience and consistency, MR is used for both NMR and MRI throughout this chapter unless otherwise stated. A knowledge of the history of MR allows us to better appreciate the remarkable progress in the field. According to the Roman philosopher, Marcus Tullius Cicero (106-43 BC), those who have no 1 knowledge of the things that took place before their birth will remain a child. 2-5,14-36 The fundamentals of conventional MR have been expounded in a number of texts. It is our intent in this chapter to chronologically review the most important milestones related to the development of MR, including the first commercially available MR scanners. Such a review, especially in a relatively short chapter, inevitably leads to difficult compromises. Those interested in more detailed discussions are referred to the cited references and references therein. We confine the scope of the discussion in this chapter to a description of the relevant contributors to the physics both before and after the Nobel Prize in 1952, a year that is often regarded as the birth of MR. In addition, a guided tour of the Fourier transform will be given in a separate section, before we discuss the development of MR imaging. Many manufacturers have developed pulse sequences and have often used different names for the same technique. For this reason we strive to classify the main classes of pulse sequences and list them according to the major manufacturers. Finally, it is not our goal to cover clinical applications or contrast agents, which are dealt with in other chapters later in this book.

Fourier Jean Baptiste Joseph Fourier (Fig. 1-1) was born on March 21, 1768 in Auxerre and died on May 16, 1830 in Paris. Fourier served three years as the secretary of the Institut d'Egypte at the beginning of the 19th century and later became prefect of the Isère département in France.6 Furthermore, he was one of the chief engineers on Napoleon's expedition to Egypt, where the torrid climate appealed to him. The focus of his life, however, was mathematics and without his Fourier transform we would not be able to create MR images. A brief overview of the Fourier transform will be given in a separate section later in this chapter. The 1920s were extremely fruitful scientifically, particularly due to the success of quantum theory and quantum mechanics. The milestones in the field of MR are summarized below. Pauli In 1924, an Austrian physicist, Wolfgang Pauli (Fig. 1-2), proposed a quantum spin number for electrons. He is best known for the Pauli exclusion principle, proposed in 1925, for which he received 12 the Nobel Prize in 1945. page 3 page 4 Add to lightbox Figure 1-1 J Fourier,1768-1830, the founder of the Fourier transform, which is the basis of most (medical) imaging modalities today. This principle says that two identical particles (fermions) cannot exist in the same quantum state.4 1 of 17 11-04-2010 23:28 Printed from: Clinical Magnetic Resonance Imaging, 3rd editio... http://www.clinicalmri.com/content/printpage.cfm?ID=HC001001 Furthermore, prior to World War II, Pauli was the first to recognize the existence of the neutrino, an uncharged and massless particle that carries off energy in radioactivity.12 Uhlenbeck In the same year as Pauli proposed his exclusion principle, George Uhlenbeck (Fig. 1-3), introduced the concept of a spinning electron, with resultant angular momentum and a magnetic dipole moment arising from the spinning electrical charge. It was Pauli's exclusion principle that led Uhlenbeck to arrive 4 at this idea. He wrote : "… it occurred to me that, since (I had learned) each quantum number corresponds to a degree of freedom of the electron, Pauli's fourth quantum number must mean that the electron had an additional degree of freedom - in other words the electron must be rotating." The concept immediately excited a number of great scientists at that time such as Bohr, Pauli, Einstein, Heisenberg and others interested in quantum theory. Besides this work, Uhlenbeck also contributed significantly to atomic structure and the kinetic theory of matter. He extended Boltzmann's equation to dense gasses and wrote two papers on Brownian motion.11 Rabi Add to lightbox Figure 1-2 W Pauli, born on 25 April 1900 in Vienna, received the Nobel Prize for Physics in 1945 for his exclusion principle.

During the early 1930s Isaac Rabi (Fig. 1-4), born in Raymanov, Austria, on July 29, 1898, set up a laboratory at Columbia University in New York which later became a major center for atomic and 13 molecular studies. page 4 page 5 Add to lightbox Figure 1-4 I Rabi was born in Austria in 1898 and awarded the Nobel Prize for Physics in 1944 for his investigation on molecular beam magnetic resonance methods.

Gorter and his co-worker Broer reported unsuccessful attempts to observe nuclear magnetic resonance in pure crystalline materials.7 This first publication with the name "Nuclear Magnetic Resonance" in Gorter's paper provided important clues to Rabi, who accepted and realized Gorter's suggestions concerning his experiments, modified them and was finally able to 2 observe resonance experimentally. This led to the publication of "A New Method of Measuring Nuclear Magnetic Moment" in 1938 where the first MR signal from LiCL (lithium chloride) (Fig. 1-5) was reported.8 Although this publication refers to Gorter's visit and unsuccessful experiment, it does not acknowledge his suggestions. Gorter's reaction to Rabi's publication was rather furious9: "I cannot deny that I felt some pride, mixed with the feeling that my contribution was somewhat undervalued though my advice was acknowledged in the Letter." Rabi was eventually awarded the Nobel Prize for physics in 1944 for his investigation on the molecular beam magnetic resonance methods. Gorter Gorter himself (Fig. 1-6) was born in Utrecht on August 14, 1907. He went to school in The Hague and studied physics in Leiden. He was the first to demonstrate the phenomenon of paramagnetic relaxation10 and narrowly missed the discovery of nuclear spin resonance. Add to lightbox Figure 1-5 First reported MR signal from LiCl by Rabi. The beam intensity is measured as a function 2,11 -4 of various values of the magnetic fields. One ampere corresponds to approximately 1.84 × 10 Tesla (T). 4 of 17 11-04-2010 23:28 Printed from: Clinical Magnetic Resonance Imaging, 3rd editio... http://www.clinicalmri.com/content/printpage.cfm?ID=HC001001 Add to lightbox Figure 1-6 C Gorter, a Dutch physicist, attempted to observe resonant heating of a substance in a strong magnetic field, without success. His negative result, however, provided the important clues to Rabi's successful experiments. (Courtesy of Leiden University.) His approach was to use a resonance property of the nuclear spins when they are placed in a magnetic field B . At the Larmor frequency, 0 where γ is the gyromagnetic ratio, Gorter knew that a magnetic dipole transition should occur if an alternating radiofrequency (RF) field B is applied perpendicular to 1 B . 0 page 5 page 6 Add to lightbox Figure 1-7 First measurement for electron paramagnetic resonance on copper at 4.76 mT carried out 5 of 17 11-04-2010 23:28
