Download or read book Contrast Agents I written by Werner Krause and published by Springer. This book was released on 2003-07-01 with total page 251 pages. Available in PDF, EPUB and Kindle. Book excerpt: Extracellular MRI and X-ray contrast agents are characterized by their phar- cokinetic behaviour.After intravascular injection their plasma-level time curve is characeterized by two phases. The agents are rapidly distributed between plasma and interstitial spaces followed by renal elimination with a terminal half-live of approximatly 1–2 hours. They are excreted via the kidneys in unchanged form by glomerular filtration. Extracellular water-soluble contrast agents to be applied for X-ray imaging were introduced into clinical practice in 1923. Since that time they have proved to be most valuable tools in diagnostics.They contain iodine as the element of choice with a sufficiently high atomic weight difference to organic tissue. As positive contrast agents their attenuation of radiation is higher compared with the attenuation of the surrounding tissue. By this contrast enhancement X-ray diagnostics could be improved dramatically. In 2,4,6-triiodobenzoic acid derivatives iodine is firmly bound. Nowadays diamides of the 2,4,6-triiodo-5-acylamino-isophthalic acid like iopromide (Ultravist, Fig. 1) are used as non-ionic (neutral) X-ray contrast agents in most cases [1].

Available in PDF, EPUB and Kindle. Book excerpt: Journalists, always very direct and in search of sensation, essentially asked me two questions on the occasion of this workshop: What were the goals of the meeting? With the improvement of diagnosis through the development of image techniques, didn't the contrast media already have their future behind them? Many answers were provided during the course of the workshop, and in order to best answer the journalists I proposed the following synopsis. 1. Since the 1979 Colorado Springs workshop organized by E. Lasser, progress has been so rapid and the newly available works so numerous that another meeting on an international level for the purpose of pre senting and discussing these advances appeared indispensable. Why not then in Europe and why not in Lyon? To expand on this progress, by 1981 the new contrast media with less-hyperosmolar molecules, still in the trial stage in 1979, were al most all available commercially for angiography, albeit at prohibitive prices. The advantages of these various media are becoming better known; moreover, in the wake of Lasser's work, our understanding of the pathophysiology of their noxious effects is also advancing rapidly owing to the use of models (for the target organs: heart, vessel wall, nervous system, kidney; and for the more general reactions: blood cells, coagulation, complement system, circulating enzymatic systems). In addition, further new molecules are currently being studied in re search laboratories. 2.
Download or read book Contrast Media written by Henrik S. Thomsen and published by Springer Science & Business Media. This book was released on 2009-02-14 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two years only after the publication of the ? rst edition of “Contrast media – Safety issues and ESUR guidelines” in our book series Medical Radiology in 2006, it appeared that a second edition was urgently needed. The ? rst edition was indeed an exceptional success with our readership and sold out rapidly, but moreover the safety of MR contrast media urgently required a reappraisal after the publication of a new and dramatic adverse reaction to some of the gadolini- based agents: the so called NSF syndrome. I am very much indebted to Professor Henrik S. Thomsen and his academic colleagues from the ESUR Contrast Medium Safety Committee for accepting the task to prepare a second edition of their remarkable book.Within a record short period of time they have been able to complete this fully revised new volume. It offers to the readers a comprehensive overview of all problems related to the use of contrast media in modern radiology and of our latest knowledge and insights in the mechanisms of adverse reactions related to contrast media. It answers all questions that radiologists and referring physicians are confronted with in their daily practice when they consider the administration of these agents to their patients.

Download or read book Advanced Practice and Leadership in Radiology Nursing written by Kathleen A. Gross and published by Springer Nature. This book was released on 2019-12-16 with total page 341 pages. Available in PDF, EPUB and Kindle. Book excerpt: Endorsed by the Association of Radiologic and Imaging Nursing (ARIN), this first of a kind comprehensive radiology nursing textbook fills a gap by addressing important subjects for patient care and professional issues, as well as, future possibilities affecting nursing practice. It serves as a resource to related nursing specialties, e.g. critical care, emergency or peri-anesthesia, and to radiologic technologists and physician assistants. The book could be used as one resource for studying for radiologic nursing certification.The textbook is subdivided into five sections that address advanced practice and leadership roles, clinical patient care topics, safety topics, including legal considerations, e.g. infection prevention and equipment. It includes a section with topics impacting the patient experience and a section on professional topics, e.g. cybersecurity, social media, research/outcomes, interprofessional collaboration, workplace violence and current trends in imaging. The authors include advanced practice providers, radiology nurse managers, educators, physicians, a physicist, a dentist, attorneys, a child life specialist, administrators and a social worker. Radiology diagnostic examinations and therapeutic procedures have become a more prominent part of patient care due to advances in technology and the ability of radiology to provide services that were traditionally done in surgery or not done because of limited knowledge. Many procedures are facilitated by the radiology nurse from initial consult to transfer to a hospital unit or discharge and follow-up. Nurses assess, monitor, administer sedation/other medications and respond to emergencies. They serve as educators, researchers, and resource personnel to the radiology department and in many instances, to the entire facility. Radiology nurses are real leaders. In order to keep up-to-date on new developments, nurses need new literature to support their clinical expertise and leadership. This book is an unparalleled resource, written by experts in their areas of interest.

Download or read book Global Productivity written by Alistair Dieppe and published by World Bank Publications. This book was released on 2021-06-09 with total page 552 pages. Available in PDF, EPUB and Kindle. Book excerpt: The COVID-19 pandemic struck the global economy after a decade that featured a broad-based slowdown in productivity growth. Global Productivity: Trends, Drivers, and Policies presents the first comprehensive analysis of the evolution and drivers of productivity growth, examines the effects of COVID-19 on productivity, and discusses a wide range of policies needed to rekindle productivity growth. The book also provides a far-reaching data set of multiple measures of productivity for up to 164 advanced economies and emerging market and developing economies, and it introduces a new sectoral database of productivity. The World Bank has created an extraordinary book on productivity, covering a large group of countries and using a wide variety of data sources. There is an emphasis on emerging and developing economies, whereas the prior literature has concentrated on developed economies. The book seeks to understand growth patterns and quantify the role of (among other things) the reallocation of factors, technological change, and the impact of natural disasters, including the COVID-19 pandemic. This book is must-reading for specialists in emerging economies but also provides deep insights for anyone interested in economic growth and productivity. Martin Neil Baily Senior Fellow, The Brookings Institution Former Chair, U.S. President’s Council of Economic Advisers This is an important book at a critical time. As the book notes, global productivity growth had already been slowing prior to the COVID-19 pandemic and collapses with the pandemic. If we want an effective recovery, we have to understand what was driving these long-run trends. The book presents a novel global approach to examining the levels, growth rates, and drivers of productivity growth. For anyone wanting to understand or influence productivity growth, this is an essential read. Nicholas Bloom William D. Eberle Professor of Economics, Stanford University The COVID-19 pandemic hit a global economy that was already struggling with an adverse pre-existing condition—slow productivity growth. This extraordinarily valuable and timely book brings considerable new evidence that shows the broad-based, long-standing nature of the slowdown. It is comprehensive, with an exceptional focus on emerging market and developing economies. Importantly, it shows how severe disasters (of which COVID-19 is just the latest) typically harm productivity. There are no silver bullets, but the book suggests sensible strategies to improve growth prospects.

Download or read book Mathematics for Machine Learning written by Marc Peter Deisenroth and published by Cambridge University Press. This book was released on 2020-04-23 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fundamental mathematical tools needed to understand machine learning include linear algebra, analytic geometry, matrix decompositions, vector calculus, optimization, probability and statistics. These topics are traditionally taught in disparate courses, making it hard for data science or computer science students, or professionals, to efficiently learn the mathematics. This self-contained textbook bridges the gap between mathematical and machine learning texts, introducing the mathematical concepts with a minimum of prerequisites. It uses these concepts to derive four central machine learning methods: linear regression, principal component analysis, Gaussian mixture models and support vector machines. For students and others with a mathematical background, these derivations provide a starting point to machine learning texts. For those learning the mathematics for the first time, the methods help build intuition and practical experience with applying mathematical concepts. Every chapter includes worked examples and exercises to test understanding. Programming tutorials are offered on the book's web site.
