Motion Correction in MR: Correction of Position, Motion, and Dynamic Changes, Volume Eight provides a comprehensive survey of the state-of-the-art in motion detection and correction in magnetic resonance imaging and magnetic resonance spectroscopy. The book describes the problem of correctly and consistently identifying and positioning the organ of interest and tracking it throughout the scan. The basic principles of how image artefacts arise because of position changes during scanning are described, along with retrospective and prospective techniques for eliminating these artefacts, including classical approaches and methods using machine learning. Internal navigator-based approaches as well as external systems for estimating motion are also presented, along with practical applications in each organ system and each MR modality covered. This book provides a technical basis for physicists and engineers to develop motion correction methods, giving guidance to technologists and radiologists for incorporating these methods in patient examinations. - Provides approaches for correcting scans prospectively and retrospectively - Shows how motion and secondary effects such as field changes manifest in MR scans as artifacts and subtle biases in quantitative research - Gives methods for measuring motion and associated field changes, quantifying motion and judging the accuracy of the motion and field estimates
Hybrid PET/MR Neuroimaging
This book serves as a reference and comprehensive guide for PET/MR neuroimaging. The field of PET/MR is rapidly evolving, however, there is no standard resource summarizing the vast information and its potential applications. This book will guide neurological molecular imaging applications in both clinical practice and the research setting. Experts from multiple disciplines, including radiologists, researchers, and physicists, have collaborated to bring their knowledge and expertise together. Sections begin by covering general considerations, including public health and economic implications, the physics of PET/MR systems, an overview of hot lab and cyclotron, and radiotracers used in neurologic PET/MRI. There is then coverage of each major disease/systemic category, including dementia and neurodegenerative disease, epilepsy localization, brain tumors, inflammatory and infectious CNS disorders, head and neck imaging, as well as vascular hybrid imaging. Together, we have created a thorough, concise and up-to-date textbook in a unique, user-friendly format. This is an ideal guide for neuroradiologists, nuclear medicine specialists, medical physicists, clinical trainees and researchers.
PET/MR Imaging: Current and Emerging Applications
This book offers an excellent overview of the current applications of PET/MR imaging. Detailed information is provided on both its principal oncologic applications and its most important non-oncologic applications, such as assessment of cardiac disease, neurodegenerative brain imaging, and imaging of inflammatory disease. In addition, the future of PET/MR imaging is closely scrutinized, highlighting the anticipated major advances in the diagnostic value of hybrid imaging, the emerging role of PET/MR imaging in monitoring response in patients receiving targeted drug therapy, and progress toward the development of new tracers. An individual chapter is also devoted to pediatric imaging. The editors and authors are all well-known specialists in the field, with high levels of expertise in clinical applications and excellent publication records. The authors and editors represent both fields of hybrid imaging, in terms of nuclear medicine and radiology as to guarantee presentation of expertise and knowledge from both “worlds”. The book will be of value for all residents and consultants in radiology and nuclear medicine who have a dedicated interest in hybrid imaging.
