Magnetic Resonance Imaging (MRI) is a technique used in radiology. It is used in forming the pictures of the anatomy and the physiological processes of the body. MRI uses magnetic field gradients, strong magnetic fields and radio waves to generate an image of the organs in the body. Magnetic resonance imaging is different from a CT scan and PET scan as it does not involve X-rays and ionizing radiation. MRI is primarily used for medical diagnosis, staging of disease and monitoring without exposing the body to radiation. The major components of an MRI scanner are the main magnet, gradient system and shim coils. Main magnet is used to polarize the sample, whereas MR signal and the RF system are localized by the gradient system. Shim coils are the components used for correcting shifts in the homogeneity of the main magnetic field. This book provides comprehensive insights into the field of magnetic resonance imaging. It is a valuable compilation of topics, ranging from the basic to the most complex advancements in this field. This book is a vital tool for all researching and studying medical imaging.
