Intraoperative Mri Developments

Intraoperative imaging technologies have taken an ever-increasing role in the daily practice of neurosurgeons and the increasing attention and interest necessitated international interaction and collaboration. The Intraoperative Imaging Society was formed in 2007. This book brings together highlights from the second meeting of the Intraoperative Imaging Society, which took place in Istanbul-Turkey from June 14 to 17, 2009. Included within the contents of the book is an overview of the emergence and development of the intraoperative imaging technology as well as a glimpse on where the technology is heading. This is followed by in detail coverage of intraoperative MRI technology and sections on intraoperative CT and ultrasonography. There are also sections on multimodality integration, intraoperative robotics and other intraoperative technologies. We believe that this book will provide an up-to date and comprehensive general overview of the current intraoperative imaging technology as well as detailed discussions on individual techniques and clinical results.

Image-guided therapy (IGT) uses imaging to improve the localization and targeting of diseased tissue and to monitor and control treatments. During the past decade, image-guided surgeries and image-guided minimally invasive interventions have emerged as advances that can be used in place of traditional invasive approaches. Advanced imaging technologies such as magnetic resonance imaging (MRI), computed tomography (CT), and positron emission tomography (PET) entered into operating rooms and interventional suites to complement already-available routine imaging devices like X-ray and ultrasound. At the same time, navigational tools, computer-assisted surgery devices, and image-guided robots also became part of the revolution in interventional radiology suites and the operating room. Intraoperative Imaging and Image-Guided Therapy explores the fundamental, technical, and clinical aspects of state-of the-art image-guided therapies. It presents the basic concepts of image guidance, the technologies involved in therapy delivery, and the special requirements for the design and construction of image-guided operating rooms and interventional suites. It also covers future developments such as molecular imaging-guided surgeries and novel innovative therapies like MRI-guided focused ultrasound surgery. IGT is a multidisciplinary and multimodality field in which teams of physicians, physicists, engineers, and computer scientists collaborate in performing these interventions, an approach that is reflected in the organization of the book. Contributing authors include members of the National Center of Image-Guided Therapy program at Brigham and Women’s Hospital and international leaders in the field of IGT. The book includes coverage of these topics: - Imaging methods, guidance technologies, and the therapy delivery systems currently used or in development. - Clinical applications for IGT in various specialties such as neurosurgery, ear-nose-and-throat surgery, cardiovascular surgery, endoscopies, and orthopedic procedures. - Review and comparison of the clinical uses for IGT with conventional methods in terms of invasiveness, effectiveness, and outcome. - Requirements for the design and construction of image-guided operating rooms and interventional suites.

The authors provide step-by-step descriptions of how to perform procedures, including advice based on their clinical results. Readers will learn about the advantages and drawbacks of the various MR imaging systems, clinical indications for MR-guidance, anesthesia considerations, safety concerns related to working in a magnetic environment, and much more. Features: In-depth coverage of all MR imaging systems helps readers to make informed choices about which technique will best suit their surgical needs Guidelines on the most appropriate imaging sequences for the resection of different types of brain tumors More than 200 high-quality intraoperative photographs taken during actual procedures to orient readers who want to use MRI in the operating room Tips from the experts on safety issues, suitable magnet designs and field strengths, cost and benefit analysis, room design, equipment, and logistics Discussion of other forms of technology that have been combined with intraoperative MR-guidance, such as focused ultrasound, neurosurgical robotics, and other promising innovations This leading-edge text has everything that neurosurgeons, neuroradiologists, and interventionalists need to know to implement an intraoperative MR-guided neurosurgery program.

In the continuous effort to further improve neurosurgery, intraoperative information on structure and function of the brain has become an important tool which potentially will result in an improved outcome of neurosurgical procedures. In this book experts from different countries and neurosurgical organizations have collected information on the state-of-the-art of intraoperative imaging, MRI, CT and ultrasound. Various contributions cover the future of neuroimaging, the impact of intraoperative imaging on glioma surgery, technical and neurosurgical aspects of the different imaging modalities and systems, and economical aspects. The present book thus provides a unique and comprehensive source of information on the complex of intraoperative imaging in modern neurosurgery.

This issue focuses on MRI developments with impact on intraoperative use in neurosurgery, along with intraoperative application of the MRI. This issue, guest edited by world-renowned neurosurgeon Rudolf Fahlbusch of the University of Erlagen, Germany, serves in clearly diagnosing and treating cerebral disorders through the succinct reading and understanding of fMRIs and MRIs. The issue focuses on the intraoperative applications of epilepsy, tumors, pituitary adenomas, and glioma resection.

These are exciting times for the field of optical imaging of brain function. Rapid developments in theory and technology continue to considerably advance understanding of brain function. Reflecting changes in the field during the past five years, the second edition of In Vivo Optical Imaging of Brain Function describes state-of-the-art techniques and their applications for the growing field of functional imaging in the live brain using optical imaging techniques. New in the Second Edition: Voltage-sensitive dyes imaging in awake behaving animals Imaging based on genetically encoded probes Imaging of mitochondrial auto-fluorescence as a tool for cortical mapping Using pH-sensitive dyes for functional mapping Modulated imaging Calcium imaging of neuronal activity using 2-photon microscopy Fourier approach to optical imaging Fully updated chapters from the first edition Leading Authorities Explore the Latest Techniques Updated to reflect continuous development in this emerging research area, this new edition, as with the original, reaches across disciplines to review a variety of non-invasive optical techniques used to study activity in the living brain. Leading authorities from such diverse areas as biophysics, neuroscience, and cognitive science present a host of perspectives that range from a single neuron to large assemblies of millions of neurons, captured at various temporal and spatial resolutions. Introducing techniques that were not available just a few years ago, the authors describe the theory, setup, analytical methods, and examples that highlight the advantages of each particular method.

This text presents a comprehensive and state-of the-art approach to stereotactic and functional neurosurgery. Overarching sections include achieving stereotactic precision, defining trajectories and targets, the biophysics of stereotactic therapies, diseases and targets, and the future of functional neurosurgery. Each section is designed to be inclusive of all relevant topics, serving as an unbiased resource to new clinicians in this field or established clinicians that are aiming to better understand complementary methods. Importantly, each section and the associated chapters can be used by basic and translational scientists as well as engineers and industry to better understand and deliver innovation to the field. Chapters within each section methodically analyze traditional and recently emerging concepts and techniques; address underlying principles with examples drawn from specific diseases and applications; and cover patient selection, target selection, available stereotactic methods, nuanced surgical methods, and clinical evidence across treatment options.
