This book, Magnetic Resonance Imaging (MRI): Principles, Technology, and Clinical Applications, provides a comprehensive academic resource on the fundamentals and advancements of MRI. It begins by outlining the historical development of MRI and the discovery of nuclear magnetic resonance, followed by detailed discussions on relaxation mechanisms, signal generation, and system components such as magnets, gradient coils, and radiofrequency technology. The volume also explores advanced imaging modalities, including functional MRI, diffusion-weighted imaging, and magnetic resonance spectroscopy, emphasizing their clinical relevance. Applications in neurology, cardiology, musculoskeletal imaging, and oncology are extensively analyzed. Moreover, the text critically examines current challenges, including scan duration, motion artifacts, and safety risks, while highlighting future directions involving artificial intelligence, quantitative imaging, and hybrid diagnostic systems.
