Whole body MR screening could be interesting in future clinical practice especially for tumor patients or patients at risk for diabetes and metabolic syndrome. One disadvantage of high field imaging in the clinic is the fact that it is highly affected by in homogeneities of the transmit RF field (B1+) resulting in a reduction in the diagnostic confidence. In whole-body imaging the RF penetration can change station by station and therefore the most ideal situation would be to apply fast B1+ shimming for each individual stack. However, the current B1+ mapping methods are time consuming and are limited by SAR constraints. The recently introduced DREAM technique is very fast and can fill this gap in clinical practice as demonstrated in this whole-body water-fat resolved study. Future applications of this approach to whole body multi-contrast imaging including TSE are conceivable.
