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
Optimize diagnostic accuracy in the emergency department with Problem Solving in Radiology: Emergency Radiology, a new addition to the popular Problem Solving in Radiology series. Published in association with the American Society of Emergency Radiology, the medical reference book is designed to help experienced radiologists, residents, or emergency medicine practitioners accurately address problematic conditions and reach the most accurate diagnosis. Consult this title on your favorite e-reader, conduct rapid searches, and adjust font sizes for optimal readability. Access problem-oriented content that helps you quickly and accurately diagnose patients. Focus on the core knowledge needed for successful results with templated, concise chapters containing both traditional and unusual presentations of pathology. Each chapter will include: Typical Presentation; Variants; Mimickers (what looks like this pathology, but isn’t); and Pitfalls (how a diagnosis can be missed and how to avoid it). Stay up to date on today's hot topics in radiology, including radiation concerns when using total body CT for trauma assessment; trauma in the pregnant patient; imaging pediatric craniocerebral trauma; and penetrating trauma to the torso and chest.
This book considers in depth all the factors that influence the radiation dose and the risk associated with MDCT in children and adults. Only a small proportion of referring clinicians, radiologists, and technologists are aware of both the radiation risks and their underlying mechanisms. The book proposes detailed guidelines for optimization of the radiation dose when using MDCT. It is written by experts of international standing.
This book highlights advances and prospects of a highly versatile and dynamic research field: Therapeutic ultrasound. Leading experts in the field describe a wide range of topics related to the development of therapeutic ultrasound (i.e., high intensity focused ultrasound, microbubble-assisted ultrasound drug delivery, low intensity pulsed ultrasound, ultrasound-sensitive nanocarriers), ranging from the biophysical concepts (i.e., tissue ablation, drug and gene delivery, neuromodulation) to therapeutic applications (i.e., chemotherapy, sonodynamic therapy, sonothrombolysis, immunotherapy, lithotripsy, vaccination). This book is an indispensable source of information for students, researchers and clinicians dealing with non-invasive image-guided ultrasound-based therapeutic interventions in the fields of oncology, neurology, cardiology and nephrology.
This book addresses all pain imaging aspects related to both the central nervous system and the body (thorax, abdomen and pelvis), thus updating the international literature on the topic. By adopting a clinical-radiological approach and offering a comprehensive differential diagnosis for a number of painful syndromes (many of which can mimic one other), the work aims to support and enhance the diagnostic management of these patients, suggesting the most appropriate diagnostic algorithm. The book is divided into separate sections for each anatomical macro-area, and the chapters cover the respective topics from both clinical and radiological perspectives. Further, the book includes extensive electronic supplementary material. As such, it offers an invaluable tool for radiologists, neuroradiologists and clinicians working in internal medicine, surgery and neurology, and could also be used in residency programs for these groups.
Developments in CT technology during the last 20 years have impressively improved its diagnostic potentialities. Part of a two-volume set that covers all aspects of CT imaging, Multi-Detector CT Imaging: Abdomen, Pelvis, and CAD Applications contains easily searchable clinical specialty chapters that provide specific information without need of an
Today the cost of solid-state two-dimensional imagers has dramatically dropped, introducing low cost systems on the market suitable for a variety of applications, including both industrial and consumer products. However, these systems can capture only a two-dimensional projection (2D), or intensity map, of the scene under observation, losing a variable of paramount importance, i.e., the arrival time of the impinging photons. Time-Of-Flight (TOF) Range-Imaging (TOF) is an emerging sensor technology able to deliver, at the same time, depth and intensity maps of the scene under observation. Featuring different sensor resolutions, RIM cameras serve a wide community with a lot of applications like monitoring, architecture, life sciences, robotics, etc. This book will bring together experts from the sensor and metrology side in order to collect the state-of-art researchers in these fields working with RIM cameras. All the aspects in the acquisition and processing chain will be addressed, from recent updates concerning the photo-detectors, to the analysis of the calibration techniques, giving also a perspective onto new applications domains.
The introduction of multidetector spiral CT into clinical practice is without any doubt one of the most important technical developments in the field of computed tomography in general, and spiral CT in particular, in recent years. Indeed, multislice CT technology, based on the spiral CT technique invented by W. Kalender almost 20 years ago, has opened immense and totally new perspectives for better utilisation of contrast medium during the examination, for optimal multiplanar reconstruction and for increased patient throughput. The potential applications, more specifically in the area of CT angiography of the brain and the heart and vessels, are most interesting and definitely contribute to better patient care as well as to more effi cient utilisation of equipment. These exciting new clinical applications explain the keen desire of radiologists and other clinicians to hear and learn more about the first results obtained with this new equipment in daily clinical practice. This book will satisfy their needs. Professor Maximilian F. Reiser was among the first to install multidetector CT in his department in Munich and to gain experience with this new radiological tool. He was also able to organise a very successful and well attended international meeting on this hot topic as early as z 2000 in Starnberg, Germany.
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.
