Methods to map B1 and flip angle are often used interchangeably without regard to the subtle but important differences between these two parameters. We present a novel combination of Actual Flip-angle Imaging (AFI) and Bloch-Siegert B1 mapping to measure them simultaneously, and demonstrate how this can improve the accuracy of quantitative magnetization transfer (MT) measurements.
