We examine RF field variation on a modern 3T and illustrate T2 quantification using only PD and T2w fast spin echo images and a rapid flip angle map in the abdomen, spine, head, neck, and leg. Across the whole body at 3T or higher fields, RF field variation yields a wide variation in flip angles, requiring direct sequence modelling to achieve accurate T2.
