Book Synopsis Radiation Dose from Multidetector CT by : Denis Tack
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.

Download or read book Health Risks from Exposure to Low Levels of Ionizing Radiation written by Committee to Assess Health Risks from Exposure to Low Levels of Ionizing Radiation and published by National Academies Press. This book was released on 2006-03-23 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the seventh in a series of titles from the National Research Council that addresses the effects of exposure to low dose LET (Linear Energy Transfer) ionizing radiation and human health. Updating information previously presented in the 1990 publication, Health Effects of Exposure to Low Levels of Ionizing Radiation: BEIR V, this book draws upon new data in both epidemiologic and experimental research. Ionizing radiation arises from both natural and man-made sources and at very high doses can produce damaging effects in human tissue that can be evident within days after exposure. However, it is the low-dose exposures that are the focus of this book. So-called “late” effects, such as cancer, are produced many years after the initial exposure. This book is among the first of its kind to include detailed risk estimates for cancer incidence in addition to cancer mortality. BEIR VII offers a full review of the available biological, biophysical, and epidemiological literature since the last BEIR report on the subject and develops the most up-to-date and comprehensive risk estimates for cancer and other health effects from exposure to low-level ionizing radiation.

Scientific Committee 4-3 on Diagnostic Reference Levels and Achievable Doses, and Reference Levels in Medical Imaging: Recommendations for Applications in the United States and published by National Council of Teachers of English. This book was released on 2012 with total page 133 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diagnostic reference levels (DRLs) are used in medical imaging to indicate whether the patient radiation dose or amount of administered activity from a specific procedure are unusually high or low for that procedure. DRLs are the first step in the optimization process to manage patient dose commensurate with the medical purpose of the procedure. Achievable dose is an optimization goal, based on survey data, and typically defined as the median value (50th percentile) of the dose distribution of standard techniques and technologies in widespread use. The overarching goal is to obtain image quality consistent with the clinical objective, while avoiding unnecessary radiation. Too low an exposure, however, is also to be avoided if it results in an inadequate image. This Report represents an important continuation of NCRP reports on radiation safety and health protection in medicine and lays the foundation for the development and application of DRLs and achievable doses for diagnostic x-ray examinations. The concept of DRLs is extended to procedures other than diagnostic x-ray examinations (e.g., for interventional radiology) by the use of reference levels (RLs), which represent radiation dose levels that if exceeded prompt an evaluation of the reasons why. This Report discusses the establishment and use of RLs for fluoroscopically-guided interventional (FGI) procedures and describes why a different approach from DRLs is required to account for the greater complexity of interventional radiology compared with standard medical imaging procedures. Phantoms are models of the human body used in radiation dosimetry studies to estimate exposures to patients. The use of phantom survey data in the United States is contrasted with the use of patient-based dose data in Europe for establishing DRLs, achievable doses, and RLs. The use of phantom survey data is reviewed for determining DRLs for imaging modalities such as projection radiography, fluoro

Download or read book MDCT Protocols written by Andrea Laghi and published by Springer Science & Business Media. This book was released on 2012-04-23 with total page 263 pages. Available in PDF, EPUB and Kindle. Book excerpt: Multidetector-row computed tomography (MDCT) has become a fundamental imaging technique for the study of many anatomical districts in different clinical situations, as it provides a fast, reliable, and accurate simultaneous evaluation of different organs, including parenchyma, hollow viscera, vessels, and bony structures. It has also equipped the radiologist with the ability to explore areas that in the last decade were largely ignored by CT, especially the coronary arteries and the colon, and to limit invasive diagnostic tests (e.g., catheter angiography) to those cases in which interventional procedures are required. The examination quality and the consequent diagnostic accuracy of MDCT are the results of an optimized study technique, which nonetheless needs to be adapted to the particular clinical situation of the patient, while bearing in mind the radiation exposure. Another fundamental parameter in the optimization of MDCT is the protocol for the intravenous injection of iodinated contrast material; in these studies, multiple variables, some modifiable by the operator and others patient-dependent, must be considered based on the aims of maximizing arterial and venous enhancements whilst minimizing the dose of iodine injected, saving money, and increasing patient safety. Through the presentation of cases addressing different anatomical regions and various clinical indications, including emergency and neuro-imaging, this volume seeks to provide the general radiologist and trainee specialist with a guide to the main study protocols to be implemented in order to optimize examination quality and, consequently, facilitate the diagnostic process.
