An assessment of the role of the Middle Ages in national historiography and in modern conceptions of national identity, looking at relatively young nations, and regions which claim national traditions but were slow to achieve, or regain, separate statehood. Examples range from Ireland and Iceland through Austria and Italy to Finland and Greece.

Based on the 1st edition this 2nd edition volume provides a completely revised comprehensive overview of the current state of the development in magnetic resonance (MR) vascular imaging. The basic principles and technical features of MR angiography are outlined, consideration being given to both flow-dependent and flow-independent contrast-enhanced approaches. Specific chapters focus on image display techniques, blood flow quantification, hardware configurations, and the limitations and artifacts of MR angiography. The well-established approach of providing a clinical overview of MR angiography in different vascular areas has been continued, with the presentation of a large number of and representative MR angiograms based on current acquisition techniques. Suitable examination protocols for different vascular regions and lesions are described to facilitate correct application of the technique. Systematic comparison is made with other vascular imaging techniques.

The present volume constitutes an attempt to compile contem­ porary features of diagnosis and treatment of renal and adrenal tumors. A thorough survey of the field is ensured by the authors'' considerable scientific experience. Tumors of the kidneys and the adrenal glands are being diagnosed and treated by physicians of different medical disciplines. For both types of tumor, the pathologic cellular substrate is of crucial importance in diagnosis and therapy. In recent years significant diagnostic advances have been made, ranging from angiography through ultrasonography and computer tomography to immunology. New impulses in oncologic therapy have occurred in surgery, radiation therapy, and tumor emboliza­ tion. A further important topic is renal tumors in infants. Such tumors involve special aspects of both diagnosis and therapy and also have a distinctive prognosis. We are indebted both to Springer-Verlag, who supported us in our intention to write this book, and to our colleagues, whose help is greatly appreciated. For the authors: E.

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.
