Dear Rachel,
Not an answer to your question, but felt I should mention the
susceptibility changes caused by speaking and jaw movements (in
case you were not already aware). For example, see:
Birn RM, Bandettini PA, Cox RW, Jesmanowicz A, Shaker R. Magnetic
field changes in the human brain due to swallowing or speaking. Magn
Reson Med 1998;40:55–60.
&
Single-Shot Magnetic Field Mapping Embedded in Echo-Planar
Time-Course Imaging. Vinai Roopchansingh, Robert W. Cox, Andrzej
Jesmanowicz, B. Douglas Ward, and James S. Hyde. Magnetic Resonance
in Medicine 50:839–843 (2003)
Sincerely,
Eric
