Radioisotope Power Systems: An Imperative for Maintaining U.S. Leadership in Space Exploration

by National Research Council of the National Academies

Spacecraft require electrical energy. This energy must be available in the outer reaches of the solar system where sunlight is very faint. It must be available through lunar nights that last for 14 days, through long periods of dark and cold at the higher latitudes on Mars, and in high-radiation fields such as those around Jupiter. Radioisotope power systems (RPSs) are the only available power source that can operate unconstrained in these environments for the long periods of time needed to accomplish many missions, and plutonium-238 (238Pu) is the only practical isotope for fueling them. Plutonium-238 does not occur in nature. The committee does not believe that there is any additional 238Pu (or any operational 238Pu production facilities) available anywhere in the world.The total amount of 238Pu available for NASA is fixed, and essentially all of it is already dedicated to support several pending missions--the Mars Science Laboratory, Discovery 12, the Outer Planets Flagship 1 (OPF 1), and (perhaps) a small number of additional missions with a very small demand for 238Pu. If the status quo persists, the United States will not be able to provide RPSs for any subsequent missions.

A Radiologic Atlas of Abuse, Torture, Terrorism, and Inflicted Trauma

by B. G. Brogdon Hermann Vogel John D. McDowell

The results of aggression against humans can be hideously obvious, but may also be entirely concealed from casual inspection. Often, only exploration of the hidden recesses of the mind via psychiatric evaluation, or radiologic exploration of the inner recesses of the body can reveal the evidence of such violence. This book focuses on the latter.<BR

Radiological Anatomy for FRCR Part 1

by Abdul Rahman Alvi Philip Borg

The new FRCR part 1 Anatomy examination comprises 20 cases/images, with five questions about each. The cases are labelled 01 to 20 and the five questions are labelled (a) to (e). The authors have set out to emulate this format by gathering 200 cases which, from their experience, are representative of the cases on which candidates will be tested. The book consists of 10 tests with 20 cases each, and 5 stem questions each. The answers, along with an explanation and tips, accompany each test at the end of the chapter. This will help candidates to identify the level of anatomical knowledge expected by the Royal College of Radiologists. The aim of this book is not to replace the already available literature in radiological anatomy, but to complement it as a revision guide. Whereas radiological anatomy atlases and textbooks provide images with labels for every possible identifiable structure in an investigation, the cases in this book have only 5 labels, simulating the exam.

Radiological and Nuclear Terrorism: Their Science, Effects, Prevention, and Recovery (Advanced Sciences and Technologies for Security Applications)

by P. Andrew Karam

This book discusses multiple aspects of radiological and nuclear terrorism. Do you know what to do if there is a radiological or nuclear emergency in your city? These accidents are not common, but they have happened – and even though we have not seen an attack using these weapons, governments around the world are making plans for how to prevent them – and for how to respond if necessary. Whether you are an emergency responder, a medical caregiver, a public health official – even a member of the public wanting to know how to keep yourself and your loved ones safe – there is a need to understand how these weapons work, how radiation affects our health, how to stop an attack from taking place, how to respond appropriately in the event of an emergency, and much more.Unfortunately, the knowledge that is needed to accomplish all of this is lacking at all levels of society and government. In this book, Dr. Andrew Karam, an internationally respected expert in radiation safety and multiple aspects of radiological and nuclear emergencies, discusses how these weapons work and what they can do, how they can affect our health, how to keep yourself safe, and how to react appropriately whether you are a police officer investigating a suspect radiological weapon, a firefighter responding to a radiological or nuclear attack, a nurse or physician caring for potentially contaminated patients, or a governmental official trying to keep the public safe. To do this, he draws upon his extensive experience in the military, the several years he worked directly with emergency responders, his service on a number of advisory committees, and multiple trips overseas in the aftermath of the Fukushima accident and on behalf of the International Atomic Energy Agency, Interpol, and the Health Physics Society.

Radiology Education

by Kathryn M. Hibbert Rethy K. Chhem Teresa van Van Deven Shih-Chang Wang

This book reviews the philosophies, theories, and principles that underpin assessment and evaluation in radiology education, highlighting emerging practices and work done in the field. The sometimes conflicting assessment and evaluation needs of accreditation bodies, academic programs, trainees, and patients are carefully considered. The final section of the book examines assessment and evaluation in practice, through the development of rich case studies reflecting the implementation of a variety of approaches. This is the third book in a trilogy devoted to radiology education. The previous two books focused on the culture and the learning organizations in which our future radiologists are educated and on the application of educational principles in the education of radiologists. Here, the trilogy comes full circle: attending to the assessment and evaluation of the education of its members has much to offer back to the learning of the organization.

Radiology Illustrated: Pattern Approach for Lung Imaging (Radiology Illustrated)

by Kyung Soo Lee Joungho Han Man Pyo Chung Yeon Joo Jeong

The purpose of this atlas is to illustrate how to achieve reliable diagnoses when confronted by the different abnormalities, or “disease patterns”, that may be visualized on CT scans of the chest. The task of pattern recognition has been greatly facilitated by the advent of high-technology CT such as helical and multidetector CT (MDCT) and dual-energy CT (DECT), and the focus of the book is very much on the role of state-of-the-art MDCT. A wide range of disease patterns and distributions are covered, with emphasis on the typical imaging characteristics of the various focal and diffuse lung diseases. In addition, clinical information relevant to differential diagnosis is provided and the underlying gross and microscopic pathology is depicted, permitting CT–pathology correlation. The entire information relevant to each disease pattern is also tabulated for ease of reference. This book will be an invaluable handy tool that will enable the reader to quickly and easily reach a diagnosis appropriate to the pattern of lung abnormality identified on CT scans. And in this second edition, some more signs and several new diseases and their pattern have been developed and updated. They will be provided with imaging, clinical relevance and CT-pathology correlation. Moreover, the chapters and disease patterns in their order of presentation shall be somewhat changed for readers’ easy legibility and understanding.

Radiology Illustrated: Nutcracker Phenomenon and Nutcracker Syndrome (Radiology Illustrated)

by Seung Hyup Kim

The nutcracker phenomenon (NCP) is an accentuated phenomenon of normal subtle compression of the left renal vein (LRV) between the abdominal aorta and superior mesenteric artery. The nutcracker syndrome (NCS) is a syndrome caused by NCP, resulting in hematuria, proteinuria, or left flank pain. The established diagnostic criterion of NCP is a pressure gradient more than 3 mmHG across the compression site, and NCS has been known to be rare, but probably is not rare and in fact quite common. The most important reason why NCS is known to be rare is that the diagnosis is difficult unless invasive venous catheterization and pressure measurement confirm the pressure gradient. Doppler ultrasound is useful in measuring the flow velocity of LRV. From the velocity measured by Doppler ultrasound, we may estimate the pressure gradient. Doppler ultrasound of LRV needs technical skills and experience. Computed tomography (CT) is a popular imaging technique for patients with hematuria, and we need to be familiar with the findings of the NCP at CT. There are variations of NCP associated with vascular anatomy and posture of the patients. This book will illustrate the concepts of NCP and NCS, findings at Doppler ultrasound and CT, and variations of NCP.

A lot of interesting cases representing characteristic imaging features is newly included in the third part.

Radiology in Forensic Medicine: From Identification to Post-mortem Imaging

by Giuseppe Lo Re Antonina Argo Massimo Midiri Cristina Cattaneo

This book offers a comprehensive overview of the forensic and radiological aspects of pathological findings, focusing on the most relevant medico-legal issues, such as virtual autopsy (virtopsy), anthropometric identification, post-mortem decomposition features and the latest radiological applications used in forensic investigations. Forensic medicine and radiology are becoming increasingly relevant in the international medical and legal field as they offer essential techniques for determining cause of death and for anthropometric identification. This is highly topical in light of public safety and economic concerns arising as a result of mass migration and international tensions. The book discusses the latest technologies applied in the forensic field, in particular computed tomography and magnetic resonance, which are continuously being updated. Radiological techniques are fundamental in rapidly providing a full description of the damage inflicted to add to witness and medical testimonies, and forensic/radiological anthropology supplies valuable evidence in cases of violence and abuse.Written by international experts, it is of interest to students and residents in forensic medicine and radiology. It also presents a new approach to forensic investigation for lawyers and police special corps as well as law enforcement agencies.

Radiology Life Support (RAD-LS): A Practical Approach

by William Bush Jr

'Radiology Life Support' focuses on the adverse effects and life-threatening emergencies caused by reactions to the contrast media used in every modern radiology department. Such reactions are relatively infrequent yet can be severe and are therefore difficult to identify and then handle safely without training. All radiologists will experience at least a few such reactions throughout their career. This book teaches proper recognition and treatment of adverse contrast reactions, proper use of sedation and analgesic agents, proper management of an airway in an emergency situation and principle concepts in basic and advanced life support (including early defibrilation). The text is based on the successful training course run by the editors and sponsored by the American Roentgen Ray Society. Adverse reactions to contrast agents are somewhat difficult for physicians without practice to identify and then handle effectively. This volume is a useful aid to the identification process.
