With the increasing interest in the experimental and clinical application of molecular imaging many institutions create research groups or interdisciplinary centers focussing on the complex development process of this new methodology. The aim of this textbook of molecular imaging is to provide an up to date review of this rapidly growing field and to discuss basic methodological aspects necessary for the interpretation of experimental and clinical results. Emphasis is placed on the interplay of imaging technology and probe development, since the physical properties of the imaging approach need to be closely linked with the biologic application of the probe (i.e. nanoparticles and microbubbles). Various chemical strategies are discussed and related to the biologic applications. Reporter-gene imaging is beeing addressed not only in experimental protocols, but also first clinical applications are discussed. Finally, strategies of imaging to characterize apoptosis and angiogenesis are described and discussed in the context of possible clinical translation.

Complex disorders of the carbohydrate metabolism and associated complications cause many abnormalities detectable by radiography in the bones and joints. Mild clinical symptoms associated with very severe radiological changes were first rec ognized in relation to the gastroenterologic complications of diabetes. This phenomenon is more frequent in the skeletal system. For example, mild and painless swelling of the foot joints may often mask extremely severe bone destruction. Several other bone changes associated with diabetes are only detectable by radiography. Thus, the radiologist plays an important role in confirming these diabetic complications, furthermore he is involved in the therapeutic management of the patient. Although many details on this subject have been published, however no summarizing monograph has yet appeared. Manuals discussing diabetes include only short reviews on complications of the osseous system. The fact that the incidence of diabetes is very high, at present 1 %-2 % of the population is affected and their number is gradually increasing - dis plays the timeliness of this subject. Fifty years of experience with insulin therapy indicates that several important problems still remain to be solved. Insulin and modern oral antidia betic drugs proved extremely efficient in the management of hyperglycemia and ketosis, but the incidence of other complications has not decreased. Moreover, as the number of diabetics and their life expectancy increase, late complications become likewise more fre quent. Diabetic osteoarthropathy is one of these complications.

For more than a century, microscopy has been a centerpiece of extraordinary discoveries in biology. Along the way, remarkable imaging tools have been developed allowing scientists to dissect the complexity of cellular processes at the nano length molecular scales. Nanoimaging: Methods and Protocols presents a diverse collection of microscopy techniques and methodologies that provides guidance to successfully image cellular molecular complexes at nanometer spatial resolution. The book's four parts cover: (1) light microscopy techniques with a special emphasis on methods that go beyond the classic diffraction-limited imaging; (2) electron microscopy techniques for high-resolution imaging of molecules, cells and tissues, in both two and three dimensions; (3) scanning probe microscopy techniques for imaging and probing macromolecular complexes and membrane surface topography; and (4) complementary techniques on correlative microscopy, soft x-ray tomography and secondary ion mass spectrometry imaging. Written in the successful format of the Methods in Molecular Biology (TM) series, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step protocols, and notes on troubleshooting and avoiding known pitfalls. Authoritative and accessible, Nanoimaging: Methods and Protocols highlights many of the most exciting possibilities in microscopy for the investigation of biological structures at the nano length molecular scales.

The book introduces the fundamental aspects of digital imaging and covers four main themes: Ultrasound techniques and imaging applications, Magnetic resonance and MPJ in hospital, Digital imaging with X-rays, Emission tomography (PET and SPECT). Each of these topics is developed by analysing the underlying physics principles and their implementation, quality and safety aspects, clinical performance and recent advancements in the field. Some issues specific to the individual techniques are also treated, e.g. choice of radioisotopes or contrast agents, optimisation of data acquisition and storage, readout electronics, modelling and computer algorithms for imaging and measurement in ultrasounds and tomography applications.

This volume provides a comprehensive review of resistance induced by photodynamic therapy (PDT) in tumor cells. Understanding the underlying mechanisms in this process leads to the improvement of therapeutic modality, in combination with chemotherapy, immunotherapy, and radiotherapy. Photodynamic therapy is a minimally invasive therapeutic procedure that can exert a selective or preferential cytotoxic activity toward malignant cells. The procedure involves administration of an intrinsically non-toxic photosensitizing agent (PS) followed by irradiation at a wavelength corresponding to a visible absorption band of the sensitizer. In the presence of oxygen, a series of events lead to direct tumor cell death, damage to the microvasculature, and induction of a local inflammatory reaction. Studies reveal that PDT can be curative, particularly in early stage tumors and this volume explores the potential of PDT, but also reveals strategic approaches to overcome resistance in tumor cells.

As an addition to the European postgraduate training system for young neurosurgeons we began to publish in 1974 this series of Advances and Technical Standards in Neurosurgery which was later sponsored by the European Association of Neurosurgical Societies. This series was first discussed in 1972 at a combined meeting of the Italian and German Neurosurgical Societies in Taormina, the founding fathers of the series being Jean Brihaye, Bernard Pertuiset, Fritz Loew and Hugo Krayenbiihl. Thus were established the principles of European co operation which have been born from the European spirit, flourished in the European Association, and have throughout been associated with this series. The fact that the English language is well on the way to becoming the international medium at European scientific conferences is a great asset in terms of mutual understanding. Therefore we have decided to publish all contributions in English, regardless of the native language of the authors. All contributions are submitted to the entire editorial board before publi cation of any volume. Our series is not intended to compete with the publications of original scientific papers in other neurosurgical journals. Our intention is, rather, to present fields of neurosurgery and related areas in which important recent advances have been made. The contributions are written by specialists in the given fields and constitute the first part of each volume.

AMI E. ISKANDRIAN & ERNST E. VAN DER WALL The first edition of this book was published in 1994. Since then important advances have occurred in the field of myocardial viability. This, coupled with increasing interest by the scientific community in the broader issues of its relevance to patient care, suggested to us the need to write the second edition. We are most fortunate to have the help of a distinguished group of experts who have helped shape the field; we appreciate their commitments and contributions. Almost all chapters have been radically modified. Chapter 1 deals with pathophysiology of myocardial hibernation and stunning; Chapter 2 with apoptosis; Chapter 3 with the role of positron emission tomography; Chapters 4 and 5 with the role of single photon emission computed tomography with thallium-201 and technetium agents, respectively; Chapter 6 with the role of SPECT fatty acid imaging; Chapter 7 with the role of SPECT FDG imaging; Chapter 8 with the role of cardiac catheterization angiography; Chapter 9 with the role of echocardiography; Chapter 10 with the role of magnetic resonance imaging; and Chapter 11 with clinical applications. Finally, Chapter 12 provides a short summary.

This book offers a review of the normal histopathological anatomy, imaging techniques and diagnostic findings for a broad spectrum of clinical problems.

Based upon the research they have conducted over the past decade in the field of denoising processes for medical ultrasonic imaging, in this book, the authors systematically present despeckling methods for medical ultrasonic images. Firstly, the respective methods are reviewed and divided into five categories. Secondly, after introducing some basic mathematical tools such as wavelet and shearlet transforms, the authors highlight five recently developed despeckling methods for medical ultrasonic images. In turn, simulations and experiments for clinical ultrasonic images are presented for each method, and comparison studies with other well-known existing methods are conducted, showing the effectiveness and superiority of the new methods. Students and researchers in the field of signal and image processing, as well as medical professionals whose work involves ultrasonic diagnosis, will greatly benefit from this book. Familiarizing them with the state of the art in despeckling methods for medical ultrasonic images, it offers a useful reference guide for their study and research work.

Some 25 years ago, the coronary care unit concentrated high technology and the acutely ill patients who might benefit from it in a single, recognizable space. Since then, that space and its technical equipment have changed, as has part of its population. Acute ischemia, silent and manifest, occurs within and outside of the coronary care unit as pain, arrhythmia, or pump failure. Its detection and treatment require the utilization of many diagnostic techniques and skills, not the least of which is two-dimensional Doppler echocardio graphy, which is gaining importance. Future developments, in tandem with computer technology, may add to this importance by enabling tissue identification, spatial representation, and Doppler flow mapping. This book describes the state of the art for the practicing clinician using Doppler echocardi?graphy at the bedside of patients with acute ischemic manifestations of coronary heart disease. The first requirement is to move from the echo laboratory to the coronary care unit, emergency department, operating room, or catheterization laboratory, using equipment suited for that purpose. The second, more trying imperative is to secure good cooper Ition between those treating the acutely ill patient and the investigator who interferes with his probes. If successful ceeding in both, rewarding results can be obtained, since echocardiography is a very sensitive and specific tool for recognizing and quantifying early ischemia.

Quantitative coronary angiography has become an invaluable tool for the interventional cardiologist, providing objective and reproducible measurements of coronary artery dimensions, which can be used to study progression or regression of coronary atherosclerosis, as well as the immediate and long term effects of percutaneous interventions. Until recently, this powerful imaging technology was confined to a small number of so-called high level institutions. Fortunately, with the development of digital cardiac imaging equipment and adaptation of cine-angiographically based computer software for on-line use in the catheterization room, quantitative coronary angiography is now available to all interventionalists. This book is a timely guide for the impending QCA user, providing practical as well as theoretical and scientific information. A comprehensive evaluation of the clinical usefulness of QCA is covered, from the fundamental principles through experimental validation studies, application to clinical trials of a wide range of pharmacological and interventional therapies in the full spectrum of clinical presentation of coronary disease syndromes, evaluation of the therapeutic efficacy of various new devices for coronary intervention, together with extensive presentation of its physiological, functional and anatomical correlations, by comparison with other intracoronary measurement and imaging techniques. In addition, evolving theories and concepts in the ever topical restenosis phenomenon' after percutaneous intervention, based on serial QCA studies, are presented and discussed and a potentially unifying methodological approach to further study of this ubiquitous problem is offered. Thisbook, thanks to the collaboration of many experts in the field of intracoronary imaging and measurement, provides stimulating, interesting and practical information, both for the academic scientist and practising clinician.
