Positron emission tomography (PET) has become a valuable interdisciplinary tool for understanding physiological, biochemical and pharmacological functions at a molecular level in living humans, whether in a healthy or diseased state. The utility of tracing chemical activity through the body transcends the fields of cardiology, oncology, neurology and psychiatry. In this, PET techniques span radiochemistry and radiopharmaceutical development to instrumentation, image analysis, anatomy and modeling. PET has made substantial contributions in each of these fields by providing a,venue for mapping dynamic functions of healthy and unhealthy human anatomy. As diverse as the disciplines it bridges, PET has provided insight into an equally significant variety of psychiatric disorders. Using the unique quantitative ability of PET, researchers are now better able to non-invasively characterize normally occurring neurotransmitter interactions in the brain. With the knowledge that these interactions provide the fundamental basis for brain response, many investigators have recently focused their efforts on an examination of the communication between these chemicals in both healthy volunteers and individuals suffering from diseases classically defined as neurotransmitter specific in nature. In addition, PET can measure the biochemical dynamics of acute and sustained drug abuse. Thus, PET studies of neurotransmitter interactions enable investigators to describe a multitude …

Interview with Bette Graham, inventor of Liquid Paper and founder of the Liquid Paper Corporation, which has since been sold to the Gillette Company. The interview includes a speech given by Bette Graham before the New Enterprise Club on March 9th, 1977 as well as a previous Oral History interview conducted on May 10th, 1969 and an Oral History interview on August 3, 1977. Additionally, there is a speech that was given to the Rotary Club at the Baker Hotel. Finally, there is a clip from the Dallas Morning News from May 14th, 1980 regarding the death of Bette Graham.

Interview with Bill Clayton, Speaker of the Texas House of Representatives, concerning his recollections and experiences during the 67th session of the Texas legislature. He introduces the elections of 1980, House bills created during that time, views of active politicians, and issues debated during the session.

Interview with David McGuire, a college professor from Waldo, Kansas, regarding his education and music background, career in music education at the University of North Texas, the development of the College of Music, and band history.

Interview with former football coach and director of athletics at the North Texas State University Fred McCain, from Denton, Texas. In the interview, McCain describes his experiences from when he worked at the college during the desegregation of intercollegiate athletics.

Interview with Keith Naylor, a Texas National Guard WWII veteran and POW from Vernon, Texas, who was captured with 2nd Battalion, 131st Field Artillery (the "Lost Battalion") on Java by the Japanese. Naylor discusses joining the Guard, deployment to the Pacific and the war's start, operations at Malang on Java, the American surrender, experiences in internment at Tanjung Priok and Bicycle Camp in Batavia, transfer to Changi Camp in Singapore, work on the Burma Railway, internment at Chungkai and Linson in Thailand, and liberation. In appendix are an excerpt from a radio broadcast of Norton McGriffin in the News, three letters to Naylor's mother regarding his MIA status, and two cards from Naylor while interned.

Interview with W. L. Starnes, a businessman, an Army veteran (2nd Battalion, 131st Field Artillery, Texas National Guard), and a member of the "Lost Battalion," concerning his experiences as a prisoner-of-war of the Japanese during World War II. Starnes talks about the fall of Java and his capture, Bicycle Camp in Batavia (1942), Changi Prison Camp in Singapore (1942), building the Burma-Thailand Death Railway (1942-1944), Kanchanaburi, Thailand (1944), Saigon and Da Lat, French Indo-China (1944-1945), and his liberation.

It is evident from this chapter that there is enormous flexibility both in the selection of the nature of the radioisotope and ways to generate it, as well as in the selection of the labeling precursor to appropriately attach that radioisotope to some larger biomolecule of interest. The arsenal of radiolabeling precursors now available to the chemist is quite extensive, and without a doubt will continue to grow as chemists develop new ones. However, the upcoming years will perhaps reflect a greater effort in refining existing methods for preparing some of those precursors that are already available to us. For example, the use of solid-phase reactions to accomplish in a single step what would normally take several using conventional solvent-based reactions has already been shown to work in many occasions. The obvious advantage here is that processes become more amenable to system automation thus affording greater reliability in day-to-day operations. There are perhaps other technologies in science that have yet to be realized by the chemist in the PET laboratory that could provide a similar or even a greater benefit. One only needs to be open to new ideas, and imaginative enough to apply them to the problems at hand.

A description of some of the methods used in neuroreceptor imaging to distinguish changes in receptor availability has been presented in this chapter. It is necessary to look beyond regional uptake of the tracer since uptake generally is affected by factors other than the number of receptors for which the tracer has affinity. An exception is the infusion method producing an equilibrium state. The techniques vary in complexity some requiring arterial blood measurements of unmetabolized tracer and multiple time uptake data. Others require only a few plasma and uptake measurements and those based on a reference region require no plasma measurements. We have outlined some of the limitations of the different methods. Laruelle (1999) has pointed out that test/retest studies to which various methods can be applied are crucial in determining the optimal method for a particular study. The choice of method will also depend upon the application. In a clinical setting, methods not involving arterial blood sampling are generally preferred. In the future techniques for externally measuring arterial plasma radioactivity with only a few blood samples for metabolite correction will extend the modeling options of clinical PET. Also since parametric images can provide information beyond that of ROI analysis, …
