Available in PDF, EPUB and Kindle. Book excerpt: Computed tomography (CT) technology has changed considerably in recent years with the introduction of increasing numbers of multiple detector arrays. There are several parameters specific to multi-detector computed tomography (MDCT) scanners that increase or decrease patient dose systematically compared to older single detector computed tomography (SDCT) scanners. This document briefly reviews the MDCT technology, radiation dose in MDCT, including differences from SDCT and factors that affect dose, radiation risks, and the responsibilities for patient dose management. The document recommends that users need to understand the relationship between patient dose and image quality and be aware that image quality in CT is often higher than that necessary for diagnostic confidence. Automatic exposure control (AEC) does not totally free the operator from selection of scan parameters, and awareness of individual systems is important. Scanning protocols cannot simply be transferred between scanners from different manufacturers and should be determined for each MDCT. If the image quality is appropriately specified by the user, and suited to the clinical task, there will be a reduction in patient dose for most patients. Understanding of some parameters is not intuitive and the selection of image quality parameter values in AEC systems is not straightforward. Examples of some clinical situations have been included to demonstrate dose management, e.g. CT examinations of the chest, the heart for coronary calcium quantification and non-invasive coronary angiography, colonography, the urinary tract, children, pregnant patients, trauma cases, and CT guided interventions. CT is increasingly being used to replace conventional x-ray studies and it is important that patient dose is given careful consideration, particularly with repeated or multiple examinations.

This book was released on 2002-07-19 with total page 804 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is the newest release in the authoritative series issued by the National Academy of Sciences on dietary reference intakes (DRIs). This series provides recommended intakes, such as Recommended Dietary Allowances (RDAs), for use in planning nutritionally adequate diets for individuals based on age and gender. In addition, a new reference intake, the Tolerable Upper Intake Level (UL), has also been established to assist an individual in knowing how much is "too much" of a nutrient. Based on the Institute of Medicine's review of the scientific literature regarding dietary micronutrients, recommendations have been formulated regarding vitamins A and K, iron, iodine, chromium, copper, manganese, molybdenum, zinc, and other potentially beneficial trace elements such as boron to determine the roles, if any, they play in health. The book also: Reviews selected components of food that may influence the bioavailability of these compounds. Develops estimates of dietary intake of these compounds that are compatible with good nutrition throughout the life span and that may decrease risk of chronic disease where data indicate they play a role. Determines Tolerable Upper Intake levels for each nutrient reviewed where adequate scientific data are available in specific population subgroups. Identifies research needed to improve knowledge of the role of these micronutrients in human health. This book will be important to professionals in nutrition research and education.

This book was released on 2012-06-26 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: The growing use of medical diagnostic procedures is correlated with tremendous and undeniable benefits in the care of most patients. However, it is accompanied by growing concerns about the risks associated with diagnostic computed tomography and other procedures that utilize ionizing radiation. A number of initiatives in radiation safety in medicine have taken place in the United States and internationally, each serving different purposes. Their ultimate goals are to provide higher quality clinical management of the patient and to ensure that reasonable steps are taken to keep the exposures as low as possible without compromising diagnostic efficacy. Tracking Radiation Exposure from Medical Diagnostic Procedures: Workshop Reports provides a summary of the presentations and discussions that took place during the December 8-9, 2011, workshop titled "Tracking Radiation Exposure from Medical Diagnostic Procedures." This workshop was organized by the Nuclear and Radiation Studies Board of the National Academy of Sciences and sponsored by the Centers for Disease Control and Prevention, the U.S. Food and Drug Administration, and the U.S. Department of Health and Human Services. This workshop report was authored by a six-member committee of experts appointed by the National Academy of Sciences. This committee brought together public health regulators, physicians, manufacturers, researchers, and patients to explore "why," "what," and "how" to track exposure from medical diagnostic procedures and possible next steps.

Download or read book Environmental Health written by Dade W. Moeller and published by Harvard University Press. This book was released on 2011-06-01 with total page 539 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dramatic changes in the field of environmental health since the Third Edition was published in 2004 demand a new, radically updated version of this essential textbook. Based on the recommendations of advisory bodies and federal agency regulations, as well as a thorough review of the scientific literature, Dade W. Moeller’s Fourth Edition is the only fully current text in this burgeoning field. It features new tables and figures and revisions of those retained from previous editions. Environmental Health is also enriched with the knowledge and insights of professionals who are deeply involved in “real world” aspects of each subject covered. In eighteen chapters, students receive a complete but manageable introduction to the complex nature of the environment, how humans interact with it, and the mutual impact between people and the environments where they work or live. This new edition emphasizes the challenges students will face in the field: the local and global implications of environmental health initiatives, their short- and long-range effects, their importance to both developing and developed nations, and the roles individuals can play in helping to resolve these problems. Whether discussing toxicology, injury prevention, risk assessment, and ionizing and non-ionizing radiation, or more traditional subjects like the management and control of air, water, and food, Moeller emphasizes the need for a systems approach to analyzing new projects prior to their construction and operation. Environmental Health is indispensable reading for practitioners, students, and anyone considering a career in public health.
Download or read book Radiation Dose from Multidetector CT written by Denis Tack and published by Springer Science & Business Media. This book was released on 2012-06-05 with total page 642 pages. Available in PDF, EPUB and Kindle. Book excerpt: Computed tomography (CT) is a powerful technique providing precise and confident diagnoses. The burgeoning use of CT has resulted in an exponential increase in collective radiation dose to the population. Despite investigations supporting the use of lower radiation doses, surveys highlight the lack of proper understanding of CT parameters that affect radiation dose. Dynamic advances in CT technology also make it important to explain the latest dose-saving strategies in an easy-to-comprehend manner. This book aims to review all aspects of the radiation dose from CT and to provide simple rules and tricks for radiologists and radiographers that will assist in the appropriate use of CT technique. The second edition includes a number of new chapters on the most up-to-date strategies and technologies for radiation dose reduction while updating the outstanding contents of the first edition. Vendor perspectives are included, and an online image gallery will also be available to readers.
