Bold sequence patients test
Develop the hyperventilation protocol (speed, duration ...) and the choice of type of mask oxygenation better tolerated by patients. Sequences beginning with a low oxygen flow (2L/mn) then progressively increasing to obtain the BOLD effect required
Bold + ASL sequence
"A first sequence BOLD+ASL will be launched in ambient air. The second sequence is repeated BOLD 5 minutes after power maternal hyperventilation.~Sequences will focus on the fetus and placenta but will also include maternal liver to validate maternal hyperoxygenation."
