Book Description
The editors address the anxiety-provoking, but not uncommon, scenario of a woman learning that she is pregnant after diagnostic or therapeutic radiologic exposure, or alternately, requiring X-rays, magnetic resonance, radioisotopes, or ultrasound after she becomes pregnant. Considerations span: the mechanisms for injury by diagnostic radiations, the units and measures of radiation, the amount of radiation absorbed by the conceptus, prenatal risk assessment, clinical management, and case reports (of diseases and traumatic injuries) exemplifying decision recommendations and counseling. Appendixes guide conceptus dose calculations for X-ray exams and radionuclide studies, and list half-lives of 23 radionuclides used in nuclear medicine (5,730 years for Carbon-14).

Book Description
Whenever a diagnostic or interventional X-ray examination of a pregnant patient is considered to be necessary, conceptus dose estimation is an essential step in assessing the radiogenic risks to the unborn child. Accurate estimation of embryo/fetus radiation dose is also needed after accidental exposure of a pregnant patient from an X-ray procedure. The exposure of pregnant patients to medical X-rays is often a complex case and involves emotionally sensitive issues for both prospective parents and physicians. Conceptus dose assessment is not always easy. Medical physicists should be able to assess conceptus doses and risks from diagnostic and interventional procedures and also to place the risk in a perspective from which an informed decision can be made. Pregnant medical professionals working with radiation have many misconceptions about the risks of ionizing radiation on the unborn child. Medical radiation workers of childbearing age should be aware that careful planning and dose optimization of examinations can address their concerns and permit, in the vast majority of cases, safe performance of procedures. Pediatric patients requiring diagnostic and interventional procedures are exposed to diagnostic and interventional X-rays. Pediatric patients are more sensitive to radiation than adults and, for this reason, accurate assessment of doses and risks is needed in these cases. Medical physicists should be able to assess paediatric doses and risks from diagnostic and interventional procedures. Several techniques and tools have been developed for dose optimization of radiographic, fluoroscopic, computed tomography and fluoroscopically-guided interventional pediatric procedures. The scan parameters should be adjusted for patient size and body region. Part of Series in Physics and Engineering in Medicine and Biology.

Book Description
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.

Book Description
Radiology Fundamentals is a concise introduction to the dynamic field of radiology for medical students, non-radiology house staff, physician assistants, nurse practitioners, radiology assistants, and other allied health professionals. The goal of the book is to provide readers with general examples and brief discussions of basic radiographic principles and to serve as a curriculum guide, supplementing a radiology education and providing a solid foundation for further learning. Introductory chapters provide readers with the fundamental scientific concepts underlying the medical use of imaging modalities and technology, including ultrasound, computed tomography, magnetic resonance imaging, and nuclear medicine. The main scope of the book is to present concise chapters organized by anatomic region and radiology sub-specialty that highlight the radiologist’s role in diagnosing and treating common diseases, disorders, and conditions. Highly illustrated with images and diagrams, each chapter in Radiology Fundamentals begins with learning objectives to aid readers in recognizing important points and connecting the basic radiology concepts that run throughout the text. It is the editors’ hope that this valuable, up-to-date resource will foster and further stimulate self-directed radiology learning—the process at the heart of medical education.

Book Description
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.

Book Description
Widely regarded as the cornerstone text in the field, the successful series of editions continues to follow the tradition of a clear and comprehensive presentation of the physical principles and operational aspects of medical imaging. The Essential Physics of Medical Imaging, 4th Edition, is a coherent and thorough compendium of the fundamental principles of the physics, radiation protection, and radiation biology that underlie the practice and profession of medical imaging. Distinguished scientists and educators from the University of California, Davis, provide up-to-date, readable information on the production, characteristics, and interactions of non-ionizing and ionizing radiation, magnetic fields and ultrasound used in medical imaging and the imaging modalities in which they are used, including radiography, mammography, fluoroscopy, computed tomography, magnetic resonance, ultrasound, and nuclear medicine. This vibrant, full-color text is enhanced by more than 1,000 images, charts, and graphs, including hundreds of new illustrations. This text is a must-have resource for medical imaging professionals, radiology residents who are preparing for Core Exams, and teachers and students in medical physics and biomedical engineering.
