Efficient Bloch-Siegert B(1)(+) mapping using spiral and echo-planar readouts
The Bloch-Siegert (B-S) B(1)(+) mapping technique is a fast, phase-based method that is highly SAR limited especially at 7T, necessitating the use of long TRs. Spiral and echo-planar readouts were incorporated in a gradient-echo based B-S sequence to reduce SAR and improve its scan efficiency. A nov...
