MRI of Degenerative Disease of the Spine: A Case-Based Atlas

by Paola D'Aprile Alfredo Tarantino

This is the second edition of an acclaimed, richly illustrated and comprehensive case-based atlas focusing on MRI of degenerative changes in the osteoarticular structures of the spine. Spinal degenerative disease is highly prevalent in the general population and its incidence increases with age. At the same time, degenerative spinal conditions are one of the most common causes of pain.The book presents a comprehensive overview of the MR findings observed in degenerative disease of spinal joints, ligaments and paravertebral muscles, and offers guidance on selecting the appropriate imaging protocol, which is critical in detecting the potentially very subtle changes. The MR study protocols presented include T2-weighted sequences with fat saturation and contrast-enhanced T1-weighted sequences with fat saturation, since these sequences permit better visualization of inflammatory changes of both anterior and posterior elements of the spine.This richly illustrated second edition highlights the inflammatory component of the degenerative pathology of the spine, which in most cases is responsible for the painful symptomatology. It also discusses in detail the use of contrast medium in MRI of spinal degenerative disease. The “case-based” structure of the atlas allows easy but effective consultation by radiologists, neuroradiologists, rheumatologists, orthopedists and physiatrists, as well as students.

All cases in the book have the detailed pathological results, and the pathological specimens are also shown in some cases. It will be an ideal reference for physicians involved in the diagnosis and treatment of gynaecological diseases.

MRI of Rectal Cancer

by Mathias Langer Arnd-Oliver Schäfer

Today magnetic resonance imaging (MRI) of rectal cancer is one of the most interesting topics in radiology. Over the last decade technical refinements have strengthened the role of MRI as a first-line diagnostic strategy for accurate staging of rectal cancer. MRI is perfectly suited to predict tumor-free circumferential resection margins. Additionally, high accuracies have been reported for the T and N stages, which is comparable to transrectal ultrasound (TRUS). Novel approaches to moving table MRI serve as a platform for thoracic, abdominal and pelvic staging of rectal cancer patients within one examination. The broad spectrum of high-quality illustrations and the contribution of clinical experts provide substantial insight into the sophisticated field of rectal cancer management.

MRI of Short and Ultrashort-T_2 Tissues: Making the Invisible Visible

by Graeme M. Bydder Jiang Du

This book comprehensively covers ultrashort echo time (UTE), zero echo time (ZTE), and other magnetic resonance imaging (MRI) acquisition techniques for imaging of short and ultrashort-T2 tissues. MRI uses a large magnet and radio waves to generate images of tissues in the body. The MRI signal is characterized by two time constants, spin-lattice relaxation time (T1) which describes how fast the longitudinal magnetization recovers to its initial value after tipping to the transverse plane, and spin-spin relaxation time (T2) which describes how fast the transverse magnetization decays. Conventional MRI techniques have been developed to image and quantify tissues with relatively long T2s. However, the body also contains many tissues and tissue components such as cortical bone, menisci, ligaments, tendons, the osteochondral junction, calcified tissues, lung parenchyma, iron containing tissues, and myelin, which have short or ultrashort-T2s. These tissues are “invisible” with conventional MRI, and their MR and tissue properties are not measurable. UTE and ZTE type sequences resolve these challenges and make these tissues visible and quantifiable.This book first introduces the basic physics of conventional MRI as well as UTE and ZTE type MRI, including radiofrequency excitation, data acquisition, and image reconstruction. A series of contrast mechanisms are then introduced and these provide high resolution, high contrast imaging of short and ultrashort-T2 tissues. A series of quantitative UTE imaging techniques are described for measurement of MR tissue properties (proton density, T1, T2, T2*, T1p,magnetization transfer, susceptibility, perfusion and diffusion). Finally, clinical applications in the musculoskeletal, neurological, pulmonary and cardiovascular systems are described.This is an ideal guide for physicists and radiologists interested in learning more about the use of UTE and ZTE type techniques for MRI of short and ultrashort-T2 tissues.

Machine Agency

by James Mattingly Beba Cibralic

An engaging exploration of agency that provides students with the critical tools needed to understand and participate in debates about future machines.The great promise of artificial intelligence’s evolution lives alongside an equally great anxiety. As we develop increasingly autonomous machines that do things in the world, questions about agency—distinguishing machines that can act from those that cannot—are among the thorniest we face. A concise and probing exploration of agency, this accessible textbook provides the critical, technical, and conceptual tools needed to make sense of rapid changes in what machines can do and their role in our lives. James Mattingly and Beba Cibralic begin with an examination of foundational issues: What is agency? How does it differ from mindedness, consciousness, and intelligence? Can we attribute agency to certain machines, and if so, how and why? They then examine the social and ethical implications of building ever more complex machines, including those concerning moral status and responsibility. Drawing together ideas from philosophy and computer science as well as from information theory, literature, and the history of science, Machine Agency invites students to participate thoughtfully in critical debates about future machines.• Provides a roadmap for interrogating the concept of machine agency suitable for philosophy majors and non-majors alike• Investigates the connections between developments in AI and pressing issues in analytic philosophy• Explores the social and ethical impacts of computational systems with agency Features robust end-of-chapter exercises

Machine Ethics and Robot Ethics

by Wendell Wallach and Peter Asaro

Once the stuff of science fiction, recent progress in artificial intelligence, robotics, and machine learning means that these rapidly advancing technologies are finally coming into widespread use within everyday life. Such rapid development in these areas also brings with it a host of social, political and legal issues, as well as a rise in public concern and academic interest in the ethical challenges these new technologies pose. This volume is a collection of scholarly work from leading figures in the development of both robot ethics and machine ethics; it includes essays of historical significance which have become foundational for research in these two new areas of study, as well as important recent articles. The research articles selected focus on the control and governance of computational systems; the exploration of ethical and moral theories using software and robots as laboratories or simulations; inquiry into the necessary requirements for moral agency and the basis and boundaries of rights; and questions of how best to design systems that are both useful and morally sound. Collectively the articles ask what the practical ethical and legal issues, arising from the development of robots, will be over the next twenty years and how best to address these future considerations.
