This interactive workbook provides a systematic introduction to the key concepts, fundamental principles, working terminology, and basic applications of magnetic resonance imaging. The workbook covers the principles of magnetism and electromagnetism, nuclear magnetism, excitation and spectroscopy, spatial localization and image formation, vectors and their use in MRI, TI and T2 relaxation mechanisms, pulsing sequences, image contrast, image acquisition, signal to noise ratio, instrumentation and artifacts. The text is enhanced by explanatory line drawings and features exercise questions - with complete answers at the end of the book - for assessing mastery of the material. It contains hands-on exercises to teach radiologic technologists or clinicians with no prior knowledge of magnetic resonance the basic principles of MRI. The book also includes the second edition of the American College of Radiology glossary of magnetic resonance terminology and a list of suggested MRI reading materials for technologists.

Part 1 What is the force of attraction?: the magnetic personality; this force is so strong, it's electric. Part 2 What's in a nucleus?: getting your nuclei in a row. Part 3 Hitting the high note!: let's get excited; understanding your special peaks. Part 4 Forming an image: what are phase and frequency?; where am I? Part 5 How do we measure magnetization?: what's a vector?; let's use vectors to measure magnetization. Part 6 How they relax: fanning out; getting back in line. Part 7 Keep your finger on the pulse of the sequences: we're only partially saturated; how to make a spin echo; recovering from inversion; how to make a gradient echo. Part 8 What's black, white and in-between: how do we manipulate the contrast on MR images; what is weighting in imaging? Part 9 In what manner are the images acquired?: what is 2D single slice acquisition imaging?; what is 2D multislice acquisition imaging?; what is 2D sequential acquisition imaging;?; what is 2D interleaved acquisition imaging; what is 3D imaging? Part 10 Turn up the signal/turn down the noise: does the magnetic field strength affect SNR?; what is voxel size?; what is the number of signal averages?; what is the bandwidth?; "coils" on the surface. Part 11 Tabs for techs: magnetic personalities; shimmy dipping; who made the grade?; radio-radio; who cares about computers?; what about the operator?. Part 12 Discovering artifacts - then covering them up: wrapping it around; those shifty chemicals; who is susceptible?; Gibbs? what is Gibbs?; the hardware did it!; look who's cross-talking; don't move.
