Classic Papers in Modern Diagnostic Radiology
I am very pleased to have been asked to write the foreword to this book. The technical advances in diagnostic radiology in the last few decades have transformed clinical practice and have been nothing short of astonishing. The subject of diagnostic radiology is now very large and radiology depa- ments are involved in all areas of modern patient care.The defining event in m- ern radiology,and arguably the most significant development in radiology since Wilhelm Röntgen discovered X-rays, was the invention of the CT scanner in the 1970s.The CT scanner introduced modern cross-sectional imaging and also di- tal imaging.We now have MRI and ultrasound and these techniques are replacing many tradit...
Transesophageal Echocardiography
Transesophageal echocardiography has become an important diagnostic method for cardiologists. It offers better resolution of images in certain cases (patients with endocarditis, prosthetic valves, central and peripheral embolism) and the distinct advantage of applicability during heart surgery. In the intensive care unit or in high risk patients during general anesthesia, it allows continuous monitoring and earlier detection of irregularities. Well-known international experts discuss the present status of this new technique, from technology and indications, advantages and disadvantages, to use in the operating room.
Advances in Echo Imaging Using Contrast Enhancement
This book will familiarize the reader with recent advances in echo imaging technology with special emphasis on echo enhancing agents. Several important strides have been made in this field during the past few years, especially in the contrast enhancement of conventional and color Doppler images. The book begins with chapters on the history of contrast echocardiography, the principles of contrast echo and descriptions of new contrast agents capable of transpulmonary passage following intravenous injection. Safety issues in contrast echocardiography are also discussed. The second section of the book deals with clinical uses of echo contrast agents. Their usefulness in the identification of car...
Mechanisms in World and Mind
The topic of the reduction of mental processes to biophysical mechanisms touches at the core of the mind–body problem, a puzzle in the philosophy of mind since the days of Descartes. This book is about philosophical aspects of neuroscience, centred on perspective dualism. The topic unfolds in the discussion of mechanisms in world and mind. Neuronal mechanisms of differing complexity are described in a general way. It is shown how models of such mechanisms may be classified and assigned to levels of systems theory. Reduction strategies are applied to processes of life, mind, and consciousness. The aim is physicalistic, to explore if and how the mental may be understood in terms of biophysics and its mechanisms.
Simulation and Imaging of the Cardiac System
The ultrasound velocity tomography allows measurement of cardiac geometries for various phases in the cardiac cycle. The present tomograph makes reconstruc tions at intervals of 20 ms. Because of a lack of clear (intramural) landmarks (except the roots of the papillairy muscle), it is difficult to pinpoint spatial trajectories of particular points in the heart. Therefore, a second method was developed of injecting radiopaque markers in the heart and following their motion patterns during the cardiac cycle with help of a biplane X-ray equipment. The data obtained with both methods can be implemented in our finite element model of the heart to compute intramural stresses and strains. The resul...
Gestalten des Archivs
Adolf Brenneke (1875-1946), Archivar und norddeutscher Landeshistoriker, ist vor allem ein Klassiker der Archivwissenschaft. Nach jahrzehntelanger archivarischer Praxis lehrte er seit 1931 an der preußischen Archivschule in Berlin-Dahlem. In Verbindung mit seiner Vorlesung befasste er sich historisch-typologisch mit Gestalten des Archivs und entwarf, basierend auf dem Provenienzprinzip, eine archivische Ordnungslehre. Dabei griff er auf gedankliche Motive des Historismus zurück. So setzte er sich mit der Historik Johann Gustav Droysens, der Geschichtsauffassung Friedrich Meineckes und der geisteswissenschaftlichen Psychologie des Dilthey-Schülers Eduard Spranger auseinander. Bedingt durch...
New Developments in Quantitative Coronary Arteriography
There are few techniques that have influenced therapeutic strategies in modem cardiology to a similar extent as coronary arteriography. Bypass surgery as well as transluminal coronary angioplasty would not have been possible without coronary angiography serving as a 'midwife' in their evolu tion. Despite the widespread and long-standing use in clinical practice, however, the interpretation of coronary angiograms has not changed very much since the early days. Most angiogr~s are still reviewed in a visual and semi-quantitative and thus often very subjective way. In the face of an almost exploding field for interventional catheterization including thrombolysis, balloon dilatation, and other ra...
Advances in Noninvasive Cardiology
Many noninvasive examination methods of the heart have not held out against the invasive methods, which modern cardiac therapy, surgically or with catheterization, requires. They have disappeared completely or are only used by isolated groups of researchers. However, there is an obvious tendency to apply the invasive procedures as the last diagnostic possibility. In the attempt to select clinically relevant methods, the expert authors of this book demonstrate that echocardiography, expanded with contrast and Doppler, has been developed into one of the most important noninvasive methods. The results with tissue characterization show that the possibilities of this method have not yet been full...
