This volume presents explanations of complex MRI principles, using detailed line drawings and easily understood descriptions. It describes how proton signals give rise to images, and reviews proton environments and T1 and T2 relaxation. It also evaluates the trade-offs between image quality and characteristics, then guides the reader through adjustments in image protocols and pulse sequences in order to achieve the desired quality and acquisition time.

From protons to images; proton environments and relaxation; longitudinal magnetization and T1 contrast; transverse magnetization and T2 contrast; spatial localization - magnetic field gradients; K-space - a graphic guide; creating MR images; signal-to-noise ratio, spatial resolution, and acquisition time; additional determinants of signal-to-noise ratio; motion-induced artifacts; pulse sequences -gradient echo and spin echo; preparatory pulses; multiecho techniques; T1-weighted pulse sequences; T2-weighted pulse sequences; intermediate-weighted pulse sequences; contrast agents; vascular techniques; artifacts.
