Course description:
The design and understanding of rapid imaging sequences seems to be a carefully sealed and treasured secret. A train of RF pulses and gradient pulses produce an unmanageable amount of echoes, and these echoes have to be combined and selected very meticulously to produce a useful signal for rapid imaging. How big should we choose the spoiler gradient within a gradient echo sequence, and what do we spoil? Can we use a HyperEcho to reverse a gradient echo sequence? What is the steady state and its resulting contrast?

Learning objectives:

• Description of magnetisation in spatial and Fourier domain
• Signal formation in rapid gradient echo sequences
• Signal formation in rapid spin echo sequences
• Special rapid imaging techniques
