Multidetector-Row CT of the Thorax
With the advent of multidetector-row technology, excitement has returned to computed tomography. Not only can we now image faster and with better resolution than ever before; more importantly, the development of sophisticated image acquisition techniques has enabled us to venture into areas previously considered to be beyond the scope of CT imaging. The knowledge, experience, and vision of a host of renowned international experts in cutting-edge thoracic applications of multidetector-row CT are condensed within this book. The result is a critical, comprehensive review of the novel opportunities, but also the new challenges, brought about by the development of ever-faster CT acquisition techniques.
Multidetector-Row CT Angiography
Multidetector-row CT has dramatically improved the results of computed tomography in all clinical applications, but its beneficial impact has been most striking in vascular imaging. The simplicity of acquisition and the wide availability of equipment make this modality especially suitable for routine clinical application. In this book the basic aspects of multidetector-row CT angiography are comprehensively reviewed. Individual chapters are included on technical principles, image processing techniques and contrast agent administration. All clinical applications are then discussed in depth, with lucid descriptions of the examination technique for particular clinical indications and of the findings that characterize specific diseases. Limitations and advantages in comparison with other imaging modalities are considered. A large number of high-quality black and white and color illustrations help to explain the clinical findings.
Multidetector-Row Computed Tomography : Scanning and Contrast Protocols
Multidetector-row computed tomography (MDCT) has advanced the approach to diagnostic assessment of many pathologies and now plays an integral role in imaging of both abdominal and cardiovascular diseases. The possibility to acquire diagnostic images with shorter scan duration, longer scan ranges, and/or thinner sections, MDCT has facilitated the opening of new horizons, such as interventional MDCT and functional imaging in stroke and oncology. In addition, advanced postprocessing techniques now permit high quality volumetric imaging in combination with maximum intensity projections, volume rendering, curved planar reformations and multiplanar reconstructions. This volume gathers contributions by internationally renowned specialists in the field who, through presenting their clinical experience, provide a thorough overview not only of MDCT and its practical applications, but also of workflow management in everyday clinical practice. Focussing on scanning and contrast protocols, the current advantages and disadvantages of non-enhanced vs. enhanced MDCT are discussed, along with insights into likely future developments. The volume represents an up-to-date source of technical and practically-oriented clinical information which should prove of great benefit to all who wish to improve or consolidate their knowledge and expertise in MDCT.
Multicriteria Optimization
Decision makers in many areas, from industry to engineering and the social sector, face an increasing need to consider multiple, conflicting objectives in their decision processes. In many cases these real world decision problems can be formulated as multicriteria mathematical optimization models. The solution of such models requires appropriate techniques to compute so called efficient, or Pareto optimal, or compromise solutions that - unlike traditional mathematical programming methods - take the contradictory nature of the criteria into account. This book provides the necessary mathematical foundation of multicriteria optimization to solve nonlinear, linear and combinatorial problems with multiple criteria. Motivational examples illustrate the use of multicriteria optimization in practice. Numerous illustrations and exercises as well as an extensive bibliography are provided.

Multi-Agent and Multi-Agent-Based Simulation ; Joint Workshop MABS 2004
The aim of the workshop was to provide a forum for work in both appli- tions of multi-agent-based simulation and the technical challenges of simulating large multi-agent systems (MAS). There has been considerable recent progress in modelling and analyzing multi-agent systems, and in techniques that apply MAS models to complex real-world systems such as social systems and organi- tions. Simulation is an increasingly important strand that weaves together this work. In high-risk, high-cost situations, simulations provide critical cost/benefit leverage, and make possible explorations that cannot be carried out in situ: – Multi-agent approaches to simulating complex systems are keytools in interdisciplinary studies of social systems. Agent-based social simulation (ABSS) research simulates and synthesizes social behavior in order to understand real social systems with properties of self-organization, scalability, robustness, and openness. – In the MAS community, simulation has been applied to awide range of MAS research and design problems, from models of complex individual agents - ploying sophisticated internal mechanisms to models of large-scale societies of relatively simple agents which focus more on the interactions between agents.
MRI of the Liver : Imaging Techniques, Contrast Enhancement, Differential Diagnosis
Due to the latest developments in magnetic resonance imaging for the evaluation of liver pathology, a second, completely revised and enlarged edition of this book was felt necessary – despite only three years having elapsed since the first edition. New chapters have been added covering important and highly relevant topics, among which imaging of pseudolesions, imaging of neoplastic diseases in pediatric subjects, imaging of bile ducts, MR angiography and imaging pre and post liver transplantation.
MRI of the Heart and Vessels
In recent years magnetic resonance imaging (MRI) has enriched the technological potential available for the characterization of cardiovascular pathologies, adding substantial advantages to other non-invasive techniques. This technique, which is intrinsically digital and has reduced operator dependency, allows the performance of image analysis in a quantitative and reproducible manner. In virtue of its added diagnostic value and inherent refinements that allow construction of two- and three-dimensional images, MRI is gaining a primary role in the histopathological and physiopathological understanding of a large number of pathologies concerning the heart and vessels. This text is addressed both to MRI operators seeking specific technical information and to clinicians who wish to have a better understanding of the diagnostic and management advantages that MRI can offer.
MRI in Clinical Practice
The book covers the basic Physics behind MRI, quality assurance, up-to-date safety guidelines and a useful gallery of image artefacts. Part of the book focuses on the specific areas of the body in which MRI is currently exploited, describing how MRI is performed in practice. In each of these sections, a common theme is followed with illustrations of MR images acquired with clinically relevant settings and typical imaging protocols are also explicitly stated. Additional information is provided which includes a subjective view of the strengths and weaknesses of MRI in comparison to other imaging modalities. As well as covering routine clinical techniques, the latest advanced methods (e.g. spectroscopy, fMRI, diffusion, high field MRI) are discussed and placed into the context of clinical application.

Monitors of Organic Chemicals in the Environment : Semipermeable Membrane Devices
Modern, industrialized societies depend on a wide range of chemical substances such as fuels, plastics, biocides, pharmaceuticals and detergents for maintaining the high quality lifestyle to which we aspire. The challenge is to ensure that while we enjoy the benetsof thes esubstances,theirinevitablereleaseintoourbiosphere does not result in unwanted human and ecosystem exposures, and the risk of - verse effects. One response to this challenge has been the extensive effort to detect and analyze or monitor a multitude of chemicals in a variety of environmental media, especially toxic organic compounds in air, water, soils and biota. An extensive literature on these traditional techniques has evolved over the years.

Monetary Policy and the German Unemployment Problem in Macroeconomic Models : Theory and Evidence
Having the high unemployment in Germany in mind, this book discusses how macroeconomic theory has evolved over the past forty years. It shows that in recent years a convergence has taken place, with modern models embodying a Keynesian transmission mechanism, monetarist policy implication, and modeling techniques inspired by new classical economics and real business cycle theory. It also probes in which direction models may be extended from here. Empirically, the book uses different econometric techniques to investigate the relevance and implications of different macroeconomic theories for German data. A key question this book investigates is the role of demand and supply side conditions for the increase in the German unemployment rate. On a policy level, the book relates the implications of the different theories to the ongoing debate on the appropriate roles of demand and supply side policies for curing the German unemployment problem.
