A parallel transmission RF pulse design is presented to measure regional oxygen extraction fraction at 7 T based on the TRUST method. Initial phantom results showed the feasibility of the method, but further in vivo studies are needed for the validation of this approach.
EPI images acquired on an oil phantom with a pulse voltage of 180V and different numbers of repetitions of the saturation module. The left, middle, and right columns show 1, 2, and 3 repetitions of the saturation module, respectively. The bottom, middle, top rows show images acquired at the bottom, in the middle, and at the top of the inversion slab, respectively.
Schematic of the labelling strategies for the proposed method. A cylindrical ROI is chosen.
