MRI Workbook 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.
