Abstract:
:A chart for organizing, teaching, and recording the magnetic resonance (MR) pulse sequences used for brain and cervical spine imaging is described. The chart helps document workable sequences and facilitates comparisons between different sequences. It has also been helpful in instructing residents and fellows how to approach an MR examination logically.
