MRI Made Easy (for Beginners)This book explains all the basic entities related to magnetic resonance imaging (MRI) for the beginners. It begins by explaining basics of magnetism, magnetic field, and basic principles behind MRI. Scanning parameters, accessory techniques, MR interpretation, clinical applications of MRI, sequences and artifacts are discussed briefly with representative pictures. Different kinds of MR instrumentation, scanning options are also explained based on which we can chose the instrument to identify a particular ailment. While using MR imaging safety options should also be considered as it may damage skin, and tissue heating. Principles and advantages of neuroimaging is discussed, which helps in interpreting MR imaging apart from anatomical and pathological knowledge of the brain. Bodyimaging is the new aspect of MRI, which helps to assess staging and treatment planning in musculoskeletal tumors. Other instrumentation discussed here includes MR angiography, MR diffusion and its clinical applications, MR spectroscopy, MR Cholangiopancreatography. Advancement and higher MR technologies like 3-Tesla MRI which is superior in epilepsy, inner ear and functional imaging are also discussed briefly. |
