Ultrafast Mri

The imaging potential of the MR experiment continues to evolve. In recent years, an increasing number of fast and ultrafast imaging strategies has been described. In this evolu tion the definition of the terms fast and ultrafast has been blurred. Hence they are frequently used interchangeably. The evolution of these methods has been based on two related, yet separate developments: an increasingly thorough understand ing of the complexities inherent to pulse sequence design and the increasing availability of stronger and faster gradient sys tems. The combination of these two factors has laid the foun dation for vast reductions of MRI data acquisition times. Min utes have been replaced by seconds. Beyond shortening MR examination times and thereby increasing patient throughput, a most significant consequence has been the ability to acquire complex MR image sets within the time confines of a single breath-hold. The constraints placed by the presence of respi ratory motion have thus been effectively eliminated. Ultrafast breath-held data acquisition strategies already represent the backbone of many abdominal, thoracic and even pelvic imaging protocols. The enhanced image quality permits full exploitation of the unsurpassed soft tissue contrast inherent to the MR experiment. Beyond improving the quality of ex isting applications, the implementation of ultrafast imaging techniques has permitted the exploration of new imaging in dications, particularly in the area of perfusion and diffusion as well as ultrafast 3D imaging.

Hardbound. This volume contains a selection of papers presented at the 2nd International Symposium on Ultrafast Magnetic Resonance Imaging in Medicine (ISUM '99) organized by the Japan Society of Magnetic Resonance in Medicine (JMRM). The symposium consisted of 32 keynote lectures and scientific sessions, 61 posters discussions and 7 educational lectures.Participants included chemists, physicists, biologists, medical scientists and technologists from 10 countries. Over 30 top-level researchers in the field were selected as invited lecturers. Ultrafast Magnetic Resonance Imaging in Medicine contains the most updated data and overviews in the areas of hardware development, pulse sequence, MRA, fMRI, Diffusion/Perfusion, MRS and Applications (abdomen, pelvis, thorax, heart) and fast and ultrafast MRIs. Main features of this book include a reference guide charting the evolution of medical imaging toward the 21th century in variou

This book offers a comprehensive overview of the use of breast MRI for screening high-risk women, including those with familial-genetic hereditary predisposition and previous chest radiation therapy, typically lymphoma survivors. It discusses the historical background of studies and research that provided the body of evidence in favor of MRI screening of these women. Technical and clinical topics are treated in dedicated chapters, including models for individualized risk estimation, radiogenomics of breast cancer in high-risk women, computer-aided detection/diagnosis and machine learning systems applied to breast MRI, and psycho-oncology issues. Alternatives to breast MRI screening such as pharmaco-prevention and prophylactic mastectomy are also discussed, taking into account the public debate on the “Angelina Jolie” effect. The high breast cancer risk model is proposed as a paradigm for personalized medicine. This book will be of interest to radiologists, surgeons, oncologists and to all professionals devoted to female healthcare.

Breast MRI: State of the Art and Future Directions provides a comprehensive overview of the current applications of breast MRI, including abbreviated MRI, as well as presenting technical recommendations, practical implementation and associated challenges in clinical routine. In addition, the book introduces novel MRI techniques, multimodality imaging, and advanced image processing coupled with AI, reviewing their potential for impeding and future clinical implementation. This book is a complete reference on state-of-the-art breast MRI methods suitable for MRI researchers, radiographers and clinicians. Breast cancer is one of the leading causes of death among women with early detection being the key to improved prognosis and survival. Magnetic resonance imaging (MRI) of the breast is undisputedly the most sensitive imaging method to detect cancer, with a higher detection rate than mammography, digital breast tomosynthesis, and ultrasound. Spans the whole spectrum of breast MRI, including basic imaging techniques, indications, interpretation, and the latest cutting-edge techniques Reviews multiparametric MRI and abbreviated protocols, providing an outlook on the future of this technique Discusses the predictive and prognostic value of MRI as well as the evolving field of radiomics/genomics and AI
