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.
