MRI Workbook for Technologists
Carolyn Kaut · Medical Entomology and Zoology · 1992
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.
