Optimized interferometric encoding of presaturated TurboFLASH B 1 mapping for parallel transmission MRI at 7 T: Preliminary application for quantitative T 1 mapping in the spinal cord.

Optimization of the satTFL interferometric encoding improves B maps in the spinal cord, in particular in low SNR regions. A linear correction of the satTFL was additionally shown to be required. The method was successfully used for quantitative phantom and in vivo T mapping, showing improved results compared to non-optimized satTFL thanks to improved pTx-pulse generation.
