Data mining can help pinpoint hidden information in medical data and accurately differentiate pathological from normal data. It can help to extract hidden features from patient groups and disease states and can aid in automated decision making. Data Mining in Biomedical Imaging, Signaling, and Systems provides an in-depth examination of the biomedical and clinical applications of data mining. It supplies examples of frequently encountered heterogeneous data modalities and details the applicability of data mining approaches used to address the computational challenges in analyzing complex data. The book details feature extraction techniques and covers several critical feature descriptors. As machine learning is employed in many diagnostic applications, it covers the fundamentals, evaluation measures, and challenges of supervised and unsupervised learning methods. Both feature extraction and supervised learning are discussed as they apply to seizure-related patterns in epilepsy patients. Other specific disorders are also examined with regard to the value of data mining for refining clinical diagnoses, including depression and recurring migraines. The diagnosis and grading of the world's fourth most serious health threat, depression, and analysis of acoustic properties that can distinguish depressed speech from normal are also described. Although a migraine is a complex neurological disorder, the text demonstrates how metabonomics can be effectively applied to clinical practice. The authors review alignment-based clustering approaches, techniques for automatic analysis of biofilm images, and applications of medical text mining, including text classification applied to medical reports. The identification and classification of two life-threatening heart abnormalities, arrhythmia and ischemia, are addressed, and a unique segmentation method for mining a 3-D imaging biomarker, exemplified by evaluation of osteoarthritis, is also present

Written by an interdisciplinary team of medical doctors, computer scientists, physicists, engineers, and mathematicians, Correction Techniques in Emission Tomography presents various correction methods used in emission tomography to generate and enhance images. It discusses the techniques from a computer science, mathematics, and physics viewpoint. The book gives a comprehensive overview of correction techniques at different levels of the data processing workflow. It covers nuclear medicine imaging, hybrid emission tomography (PET-CT, SPECT-CT, PET-MRI, PET-ultrasound), and optical imaging (fluorescence molecular tomography). It illustrates basic principles as well as recent advances, such as model-based iterative algorithms and 4D methods. An important aspect of the book is on new and sophisticated motion correction techniques in PET imaging. These techniques enable high-resolution, high-quality images, leading to better imaging analysis and image-based diagnostics. Reflecting state-of-the-art research, this volume explores the range of problems that occur in emission tomography. It looks at how the resulting images are affected and presents practical compensation methods to overcome the problems and improve the images.

This volume highlights the remarkable new developments in brain imaging, including those that apply magnetic resonance imaging (MRI) and Positron Emission Tomography (PET), that allow us to non invasively study the living human brain in health and in disease. These technological advances have allowed us to obtain new and powerful insights into the structure and function of the healthy brain as it develops across the life cycle, as well as the molecular make up of brain systems and circuits as they develop and change with age. New brain imaging technologies have also given us new insights into the causes of many common brain disorders, including ADHD, schizophrenia, depression and Alzheimer's disease, which collectively affect a large segment of the population. These new insights have major implications for understanding and treating these brain disorders, and are providing clinicians with the first ever set of biomarkers that can be used to guide diagnosis and monitor treatment effects. The advances in brain imaging over the last 20 years, summarized in this volume, represent a major advance in modern biomedical sciences. The Authors of this volume are leaders in the development of PET and MRI methods as well as clinical and translational researchers skilled in their use in patients with brain disorders. Individual chapters of this volume focus on the use of specific methodologies, covering the full range of PET chemistry based approaches as well as MRI methods from structural and diffusion tensor based imaging, to functional MRI of functional brain circuitry, to pharmacological MRI and MRI spectroscopic molecular imaging.

Optical Coherence Tomography represents the ultimate noninvasive ocular imaging technique although being in the field for over two-decades. This book encompasses both medical and technical developments and recent achievements. Here, the authors cover the field of application from the anterior to the posterior ocular segments (Part I) and present a comprehensive review on the development of OCT. Important developments towards clinical applications are covered in Part II, ranging from the adaptive optics to the integration on a slit-lamp, and passing through new structural and functional information extraction from OCT data. The book is intended to be informative, coherent and comprehensive for both the medical and technical communities and aims at easing the communication between the two fields and bridging the gap between the two scientific communities.

Diagnostic errors are important in all branches of medicine because they are an indication of poor patient care. As the number of malpractice cases continues to grow, radiologists will become increasingly involved in litigation. The aetiology of radiological error is multi-factorial. This book focuses on (1) some medico-legal aspects inherent to radiology (radiation exposure related to imaging procedures and malpractice issues related to contrast media administration are discussed in detail) and on (2) the spectrum of diagnostic errors in radiology. Communication issues between the radiologists and physicians and between the radiologists and patients are also presented. Every radiologist should understand the sources of error in diagnostic radiology as well as the elements of negligence that form the basis of malpractice litigation.

This book has grown out of our shared experience in the development of the Stanford Synchrotron Radiation Laboratory (SSRL), based on the electron-positron storage ring SPEAR at the Stanford Linear Accelerator Center (SLAC) starting in Summer, 1973. The immense potential of the photon beam from SPEAR became obvious as soon as experiments using the beam started to run in May, 1974. The rapid growth of interest in using the beam since that time and the growth of other facilities using high-energy storage rings (see Chapters 1 and 3) demonstrates how the users of this source of radiation are finding applications in an increasingly wide variety of fields of science and technology. In assembling the list of authors for this book, we have tried to cover as many of the applications of synchrotron radiation, both realized already or in the process of realization, as we can. Inevitably, there are omissions both through lack of space and because many projects are at an early stage. We thank the authors for their efforts and cooperation in producing what we believe is the most comprehensive treatment of synchrotron radiation research to date.

The eontinual growth of radiologie information makes it inereas- ingly diffieult for the praetitioner to maintain eurrent clinieal knowledge. Radiologie textbooks eontaining mueh material for the praetieing clinieian are often impossible to review thoroughly. Such radiographie texts deseribing the hand as a window to the understanding of systemie disease are available, but there has been an absence of books whieh present an easily assimilated synopsis of this material. Professor Thijn has elegantly presented all the major and many minor features of diseases and eonditions that affeet the skeleton, using hand roentgenograms as a window. He has also included numerous illustrations of key assoeiated roentgeno- graphie manifestations elsewhere in the body. His organized pre- sentation of eaeh entity, including introductory remarks, radio- graphie findings in the hand and other sites, differential diagno- sis, and key referenees, forms a strueture through whieh an ap- propriate evaluation of a clinieal ease may be made. The eoneise synopsis of eaeh disease entity, weIl illustrated by superb roentgenograms, provides an exeellent strueture for both the student first learning about such eonditions and the praetitioner researehing an explanation for partieular roentgeno- graphie findings. Professor Thijn has attempted, and I believe has sueeeeded admirably, to provide a souree from whieh a student or praeti- tioner of radiology may readily arrive at a differential diagnosis of an observed radiographie feature.

Oncological surgeons are often requested in their clinical practice to identify and manage uncommon and complex situations. It is therefore of the utmost importance that they are well aware of the most recent technological evolutions, in order to achieve the best possible results in term of oncological outcome, with a concern on quality of life and economical issues. Furthermore, new techniques can give a fundamental contribution in overcoming the limitations of standard approaches.

An essential aim of this book is to underline the great importance and the need of an effective coordination of multi-disciplinary care among surgeons, medical oncologists, radiation therapists, plastic surgeons and ancillary services, in order to optimise patient outcome.

Due to the ever increasing interest in the use of non-invasive ultrasonic methods in medical diagnostics on the one hand and the specific effects of ultrasound in medical therapy on the other, the questions of safety and optimal applications are topical and of great importance. For this reason the symposium "Ultrasound Interaction in Biology and Medicine," initiated and supported by the "International Organization of Medical Physics," took place. The organizers were the Institute of Applied Biophysics of the Martin-Luther-University, Halle (Saale), German Democratic Republic, in association with the Society for Physical and Mathematical Biology of the GDR along with other scientific organizations. Renowned and internationally noted specialists in the field of ultrasonics reported on the latest findings regarding the biological interaction of ultrasound, which promised future improvements in the methods of ultrasonic diagnostics and gave and up-to-date insight into the biological effectiveness of ultrasound. We are pleased to be able to publish selected contributions to this symposium collected in one volume. The methods of investigation, theoretical considerations and results concerning the interaction of ultrasound on molecular, cellular and system levels contained herein will remain up-to-date for a long time to come, providing thought provoking material for further inter-disciplinary basic research and medical application.

Rheumatic inflammatory diseases represent a steadily increasing group of disorders that have considerable social impact through affected patients' worsening quality of life and require engagement in the health field. Among these, rheumatoid arthritis stands as the most frequent pathology, and the hand is the most typical affected area. The incidence of rheumatic arthritis, as indicated by recent epidemiological studies, is bound to undergo a further significant increase in the future. There is, therefore, a need for careful diagnosis of the disease, based on clinical criteria designed by the American College of Rheumatology and Diagnostic Imaging. The latter provides an objective assessment of the extent and severity of joint involvement.
Rheumatoid Hand includes 25 tables of clinical and radiological cases. The text analyses the capability of diagnostic imaging (conventional radiology, ultrasonography and magnetic resonance) to identify the early stages and the activity of disease, allowing the rheumatologist to decide on an effective therapeutic plan.

Echo-encephalography, introduced by LEKS ELL in 1955, has gained increasing importance for the early detection of numerous intracranial lesions in the last decade. The main advantage of this diagnostic procedure lies in the fact that it permits a rapid orientation about the spatial relationships within the skull without stressing or endangering the patient. Although this method alone only rarely allows a complete diagnosis, the echo-encephalographic findings always indicate which further diagnostic measures are most suitable for establishing the diagnosis with the greatest accuracy in every case. However, the correct interpretation of an echo-encephalogram is possible only, if the findings which are assumed to be pathological are evaluated in the light of the clinical symptomatology. Since JEPPSSON'S excellent monograph on the origin of the midline echo and its importance for the diagnosis of intracranial expansivities, published in 1961, a great deal of work has gone into the development of echo-encephalography all over the world. For this reason the possibilities of this procedure today go far beyond the mere demonstration of a supratentorial shift. Now we can frequently outline the width of the ventricles exactly and localize tumors or hematomas by means of abnormal reflections. Since a detailed description of the technique, application and present-day diagnostic uses of echo-encephalography has not been available as yet, we undertook to fill this gap in the German literature in 1967 with a monograph summarizing the hitherto existing experience as well as our own extensive case mate rial.

Liver surgery has made extraordinary progress over the past 40 years, evolving from the first, timid partial resections in the 1950s to today's major resections and organ transplants. Examining the rea- sons for this progress, one cannot but be impressed by the substan- tial role that has been played by radiology. Formerly, preoperative planning was based on only nebulous scintigraphic scans. Today, surgeons have at their disposal a wide variety of radiological modalities for diagnosis and topography which are precise enough to exclude most operative surprises. Fur- thermore, the radiologist is becoming increasingly involved in ther- apy: prior to operation for tumor reduction by embolization and after resection for treatment of local complications - which could otherwise necessitate difficult and occasionally dangerous reoper- ations. As the author writes in his preface, it is not really astonishing that a radiologist is publishing a book on this topic, and he must be congratulated for his work-up, which combines important personal experience with a complete analysis of published papers on this topic.

Recent radiologic procedures in bone and joints, some of which eliminate the need for surgery are exposed, including: trephine biopsies of the thoracic and lumbar spine, sacro-iliac joints, peripheral bones synovial membrane and soft tissues, using either fluoroscopic echographic or CT guidance - chemonucleolysis - vascular embolization of skeletal tumors and management of vertebral hemangiomas - selective steroid injection in a broad spectrum of diseases including vertebral facet syndrom, cervicobrachial nerve root pain, rotator cuff calcium deposits, bone cysts. This unique volume supplies the reader with complete information regarding the performance of all these techniques.

The twentieth century was the century of the development of morphological cerebral imaging by tomodensitometry (TDM) and Magnetic Resonance Imaging (MRI). In recent years new brain imaging methods were used in adults with neurological lesions, and more recently in adults with psychiatric disorders. Now it is also possible to use, most of these morphological and functional brain imaging methods in children.
This book presents the main morphological and functional brain imaging methods that we can use in the child. Two main applications are developped: physiopathological and therapeutical interest. The physiopathological approach is of a great interest, coupled with clinical evaluation in psychomotor disorders like hyperkinetic or Tourette syndrom, and in developmental disorders like autistic syndrom, mental retardation, Rett Syndrom ...

The primary purpose of this book is to bridge the gap be tween the practice of clinical medicine and diagnostic radi ology. It is intended primarily for utilization by medical students in training and by nonradiologist physicians. In this world of rapidly expanding knowledge in the many specialties of medicine, it is becoming increasingly difficult for many physicians to stay abreast of the newer and constantly changing modalities of diagnosis as well as the therapeutic regimens of the common as well as the less common disease processes within their realm of practice. This book will enable the busy clinician to utilize the consultative services offered by his or her colleagues in diagnostic radiology with maximum effectiveness. The most common clinical applications of the more recent imag ing modalities (i. e. , nuclear medicine, ultrasound, comput erized tomography, and magnetic resonance imaging) have been categorized and condensed into a format that will be both comprehensible and useful on a daily basis for those physicians routinely requesting these diagnostic examina tions for their patients. For simplicity, the book is divided, whenever feasible, into organ systems and subdivided into the multiple classifications of pathologic states (i. e. , con genital, trauma or iatrogenic, inflammatory, and neo plasm). In addition, there are brief comments related to the vii specific advantages and disadvantages as well as the cost effectiveness of each modality.
