TL;DR: The following are the reported benign causes of 1 8-FDG uptake that should be considered in interpreting whole body scans to decrease the rate of false-positive results in oncologic patients.

TL;DR: With the development of new scintillators that provide more light output and are denser than those available in the 1980s and considerably faster than BGO, there is new interest in the application of TOF techniques for future tomograph designs.

TL;DR: Nuclear medicine physicians must speak the language of their referring physicians who are anatomically oriented and used to the exquisite morphologic detail of computed tomography (CT) and magnetic resonance imaging (MRI).

TL;DR: This report has emphasized the attributes of positron emission tomography (PET) through a discussion of the historical development with attention to limitations or factors that are of importance in using and further developing this technology.

TL;DR: The use of PET with the estrogen analogue 16 alpha-[18F]fluoro-17 beta-estradiol (FES) to monitor receptor function and response to hormonal therapy opens up intriguing new ways to monitor patients with breast cancer at a cellular level.

TL;DR: FDG-PET imaging provides physiologic and metabolic information that characterizes lesions that are indeterminate by CT and that accurately stages the distribution of lung cancer and several studies have documented the increased accuracy of PET compared with CT in the evaluation of the hilar and mediastinal lymph node status in patients with lung cancer.

TL;DR: Teleradiology, including telenuclear medicine, is one of the more well-defined telemedicine services and Techniques have been developed for the acquisition and digitization of images, image compression, image transmission, and image interpretation.

TL;DR: Several factors that may have affected results, and potentially underestimated the value of scintigraphy in the diagnosis of RSD are examined, including duration of patient's symptoms, age of the patient population evaluated, location of the disease, and the varying scintigraphic scan interpretation criteria used.

TL;DR: An integrated framework for understanding the radiopharmaceuticals that are available at this time is provided, describing both their strengths and weaknesses, and to look forward to some of the improvements that might be anticipated in the next decade.

TL;DR: The lung is an ideal organ for study with positron emission tomography (PET) because structure-function relations are homogeneous over larger areas than in other organs, and many physiologic and metabolic processes can be studied, including pulmonary blood flow, ventilation, vascular permeability, endothelial receptor and enzyme function, among others.

TL;DR: With improved technique and instrumentation it is no longer sufficient to indicate a focal abnormality in the ankle or foot on bone scintigraphy, and more precise information about perfusion, blood pool, and specific location of a lesion can be obtained by high resolution and tomographic images.

TL;DR: The introduction of F-18 deoxyglucose represents another major step toward practical clinical use of positron-emitting tracers and achieves the transition from the postulation of the existence of positrons to their use in a wide variety of diseases.

TL;DR: The Internet stands at the forefront of telecommunications in medicine as mentioned in this paper and is used for medical education, teaching, and research, as well as clinical practice, which will be affected in numerous different ways by these advances.

TL;DR: PET is unequaled in establishing the presence or absence of coronary artery disease (CAD) as well as for assessment of myocardial viability and should provide therapeutic approaches to enhancing the treatment of patients with heart disease of diverse etiologies.

TL;DR: Thallium-201 chloride imaging and 99mTc-sestamibi imaging have an important role in the assessment of tumor response to chemotherapy and in the quantification of tumor viability.

TL;DR: The bone scan can be a part of the algorithm for evaluating chronic pain syndromes including reflex sympathetic dystrophy and the complimentary roles of bone scanning and imaging with gallium-67 citrate or radiolabeled leukocytes has proven useful in the evaluation of acute or chronic osteomyelitis.

TL;DR: PET provided a level of precision in the measurement of blood flow that opened up the modern era of functional human brain mapping and paved the way for the explosive rise in the use of MRI in functional brain imaging.

TL;DR: In this presentation, the common clinical pediatric problems ( appendicular growth aberrations, hip pain, back pain, some aspects of trauma, and inflammatory and infectious processes that can be addressed by nuclear imaging will be discussed.

TL;DR: An overview of potentially useful isotopes is presented and it is determined that the bulk of the increase lies in the costs to establish and staff the facility, and the costs of cyclotron facility costs have increased dramatically since 1966.

TL;DR: Eventually, conceptual searching in which the computer searches for related ideas, without having to be given all the related keywords, may become a reality, allowing energies to be focused on results of the search, not the search itself.

TL;DR: Improvements in the speed of the Internet will allow inclusion of more images at higher resolution and more extensive use of cine, and a better understanding of how to use this new media will spur continued expansion in use of the internet for nuclear medical education.

TL;DR: Along with resurgence of physical activity during these fitness conscious times, there is increasing participation by people of all ages in sporting activities, which means the number of sports-related injuries presenting for medical attention has increased.

TL;DR: This reprint of an article that first appeared in Nucleonics in 1966 provides a unique perspective of the introduction of the cyclotron into clinical medicine and medical research.

TL;DR: Nuclear medicine physicians need to be prepared to properly interpret findings unrelated to trauma and to direct the evaluation of patients toward the correct diagnosis and subsequent management.

TL;DR: Nuclear Medicine was one of the earliest imaging modalities to adopt the use of computers for acquisition, processing, storage, and display of digital images.

TL;DR: Familiarity with the varying patterns of abnormality associated with different disease is vital to correct assessment and, for a particular scan abnormality, several conditions may have to be considered.

TL;DR: A 52-YEAR-old female presented with acute onset of left upper quadrant pain, nausea, and vomiting, which was treated with percutaneous transluminal coronary angioplasty and intracoronary urokinase infusion.

TL;DR: A 37-year-old man was admitted with a 1-month history of cough, dyspnea, sputum, and chest pain and histopathology revealed primary large cell neuroendocrine carcinoma, which was referred for chemotherapy.
