Clinical Implementation of Dynamic Parallel Transmission in 7T Brain MRI: Improved Homogeneity and Contrast Using SPACE Sequences
We demonstrate the feasibility of a time-efficient prototype dynamic pTx implementation in T2-SPACE and FLAIR-SPACE sequences, which significantly enhances signal and contrast across the brain compared with sTx, while exhibiting consistent and robust performance in a large cohort of clinical patients.
