Abstract
This paper explains that Positron Emission Tomography (PET) scanning is an advanced imaging technique that can differentiate between malignant lesions and benign lesions in almost every process in cancer diagnosis, staging and treatment because PET is more sensitive than CT scanning or Magnetic Resonance Imaging (MRI) techniques. The author explains that for PET scanning, the patient is injected with positron emitting radionuclides and placed in a tube and surrounded by a ring of detectors; when one of these high-energy photon rays is detected, the source location can be determined and mapped by a specialized software package. The paper relates that, after radiation and surgery there is considerable damage to surrounding tissue; therefore, it is often difficult to distinguish living cancer cells from morphological changes caused by surgery or tissue death caused by radiation; however, because dead tissue and cancer cells have different glucose metabolism rates, they are easy to distinguish by PET imaging.

From the Paper
"Because PET scanning is based on glucose levels, it is important that these be controlled prior to the scan. Patients are usually told to fast for 4-6 hours prior to the test. However, they can drink water and take any medications that they are on. The goal is to get the base glucose level lower than 160 mg/dL before administering the FDG or other isotope. Patients with diabetes should continue their routine of eating small meals and taking their insulin. Then these small inconveniences, PET imaging is non-invasive and causes little discomfort to the patient."

Abstract
This paper examines how nuclear medicine is a medical specialty that involves the use of radioactive isotopes in the diagnosis and treatment of disease. It looks at how positron emission tomography (PET) imaging is used extensively as diagnostic tool in the U.S. and Europe, but has limited availability in the U.K. It shows how the information obtained from these examinations can differentiate between different organs without the need for the patient to undergo surgical procedures. It also examines how, despite the long history of PET development, the costs and effectiveness of its use in routine clinical practice remain unknown. It reviews the relevant literature to determine whether PET imaging should be used more extensively in the U.K. instead of conventional nuclear medicine imaging.

From the Paper
"These researchers report that despite the long history of PET development, the costs and effectiveness of its use in routine clinical practice remain virtually unknown. However, what is known is that the bottom line for these and other advances in medical technology is clinician and patient accessibility. According to Michael Johns, "Physicians who do not have access to or choose not to utilize cutting-edge technologies could potentially limit the care provided to their patients. But for many in the developing world, the cost of new equipment and materials continues to be prohibitive. Even in the West, both public and private insurance agencies take into account the cost of a test or therapy before deciding whether to pay for it? (2001, 132)."

Abstract
This paper looks at how the different advances in brain imaging-techniques have contributed to scientists increased ability to understand the concept of memory. It looks at the advent of Computed Tomography (CT), Magnetic Resonance Imaging (MRI) and Positron Emission Tomography (PET), and what they have meant to the increased ability to understand and treat brain, and memory disorders.

From the Paper
"For example, fMRI was found useful for research by Awh and colleagues (1999) to observe brain activations during the performance of a spatial working memory task. In this investigation, subjects were given a spatial working memory task and a control task. Using fMRI the researchers found a functionally distinct, region that showed sustained activity during the spatial working memory task, confirming the location for the neural bases for that function. In the past, researchers who wanted detailed studies of human brain activity struggled because they lacked effective investigative tools. In experiments with humans the best technologies brought only limited success in mapping the processes of consciousness."

From the Paper
"Since a first glance it might be assumed the fact that PET/CT would bring some important benefits to the patients' status and living. Even though, a great disadvantage might be represented by the high cost of the equipment, which has only allowed large hospitals to achieve it Moreover, in order for the very ill persons to be helped, UPMC has developed a mobile PET/CT unit that can be brought next to them. In this way the same equipment is able to be used by more than one clinic and its cost might be shared among them. "The Mobile PET/CT unit is identical to the stationary units, except that the equipment is mounted in a tractor trailer which is parked outside the network locations. Scans are scheduled with your oncologist, and the actual procedure takes place in the trailer" . "

Abstract
How the brain functions has been of great interest to man for centuries, and in the past few decades, technology has created tools to investigate this process. This paper provides an overview of the five major imaging modalities for brain function: EEG, MEG, MRI, PET, and SPECT. The paper discusses the technology, the applications, and the future applications, as well as explores the current issues in the area. The paper includes colored photographs and figures.

From the Paper
"Functional imaging tools in current use include electroencephalography (EEG), magnetoencephalography (MEG), single photon emission computed tomography (SPECT), positron emission tomography (PET), and functional magnetic resonance imaging (fMRI). Functional brain imaging is used to diagnose and track the treatment of various brain disorders such as stroke, multiple sclerosis, epilepsy, and other psychological disorders. Functional tools are also used in complex pre-surgical planning and surgical mapping. Issues in the literature relate to the removal of artifacts and increasing resolution. Future directions of the technologies include the combination of modalities, development of surgical planning methods, clinical applications in stroke research, and future uses in epilepsy."

Abstract
Discusses early development, methods, radiology and traditional x-rays. Covers digital imaging and x-rays, computer tomography scans (CT), positron emission tomograpohy (PET) tomography and gamma rays, and thermography.

From the Paper
"The first imaging techniques developed for medicine, x-rays, were discovered in 1985 by William Roentgen, and they were first used in medicine in 1896 (Lentle and Aldrich, 1997). Early radiology was chiefly concerned with skeletal morphology."

Abstract
This paper explains that Positron Emission Tomography (PET), an
imaging technique, allows clinicians to localize safely and monitor accurately the activity of areas in the normal human brain during specific mental tasks. The author points out that the traditional methods of research, such as experiments in memorizing and observation of individuals who had suffered localized brain damage, have been facilitated by innovative methodologies, such as positron emission tomography, that connect human behavior to specific brain structures and functions. The paper relates that the research methodology will be a critical review of the scholarly and relevant literature, followed by a qualitative and quantitative analysis of how partnership between cognitive scientists and neuroscientists can be created and improved based on the technique's demonstrated efficacy in various clinical settings.

From the Paper
"PET provides clinicians with a functional brain-imaging technique to identify brain regions activated in motor, sensory, cognitive, and emotional processes. "PET is based on a simple principle: a radioactive isotope that emits [[Beta].sup.+] particles (i.e., positrons, with a mass equal to an electron but with a positive electrical charge) is artificially integrated into a biological molecule and then injected intravenously." In the various PET applications, a chemical compound that is "labeled" with a short-lived, positron-emitting radionuclide (either carbon, oxygen, nitrogen, or fluorine) is injected into the body. The activity of such a radiopharmaceutical is then measured quantitatively throughout the target organs through the use of photomultiplier-scintillator detectors."

Abstract
"Food Pets Die For" consists of seven years of research trying to get to the bottom of what people actually put into their pets' food dishes. The paper examines how author, Ann N. Martin, uses negative images, select phrases and a specific tone in order to bring her readers' attention towards the problems with commercial pet food.

From the Paper
"Being an animal's right activist vastly influences her decision on this topic. Of course Martin feels pity for animal's whose carcasses go to feed other pets as well as those pets that must eat the carcasses of their companions. Martin is not going to want to shed any good information about these companies, all the information that is shared has the intention of being as incriminating as possible to have a better chance of getting readers to find alternative foods to the commercial pet foods."

Abstract
This paper examines the technique of positron emission tomography, a technique used for imaging brain activity by measuring the flow of blood containing radioactive atoms that emit positrons. It describes the uses of PET scanning as a research tool and in the diagnosis of brain injuries. It also compares PET to other similar methods such as MRI scanning, x-raying and CT scanning.

From the Paper
"In particular, PET has been used with great success in the study of which parts of the human brain are involved in language. With the assistance of positron emission tomography, studies have shown striking evidence that there are several independent regions of the brain involved in language. Among these areas that are crucial for language and speech are Wernicke's and Broca's regions. Due to the use of these non-invasive techniques (PET, MRI etc.) we now know that these regions are significantly spread out and are not located near the conventional language regions. We can see in scans from patients that different regions of the brain are used for specific tasks. Eg. a patient hearing words, reading words and seeing words uses very different parts of the brain for each task. (Delcomyn; 1998)."

Abstract
A Maltese dog becomes the perfect pet because he or she is lovable as seen by the kisses they give, they do not shed hair because it lacks an undercoat, and they get along with other animals as seen in their gentle play with other cats and dogs. A pet owner will quickly select a Maltese as a perfect pet because this breed of dog brings joy to a pet owner's life.

From the Paper
A Maltese Dog Is a Perfect Pet When selecting a dog for a pet, a wise selection is a Maltese. Many people struggle in finding the best bet for their homes. They often want an animal that is not too big, especially if they live in an apartment. A Maltese dog often weighs only 4 to 7 pounds and may be only 9 to 10 inches tall. A Maltese dog becomes the perfect pet because he or she is lovable as seen by the kisses they give, they do not shed hair because it lacks an undercoat, and they get along with other animals as seen in their gentle play with other cats and dogs. A pet owner will quickly select a Maltese as a perfect pet because this breed of dog brings joy to a pet owner's
