After reading this chapter, you should be able:
- To present the different fat signal suppression techniques
- Describe the advantages and disadvantages of STIR sequences, fat saturation, selective excitation of water
- Specify the different families of contrast agents
- Explain their action on relaxation time and contrast
- List their contraindications and main indications
- Explain magnetization transfer and how it can improve background suppression
- Off-resonance RF pulse in relation to the peak of water
- Saturation of protons with restricted mobility (brain, muscle, liver)
- Drop in signal due to exchanges between free and bound protons
- Does not affect fluids (LCR, blood, urine) containing no bound protons
