An adiabatic T
2
Preparation
module (T
2
Prep) at high magnetic field
normally requires too much energy to allow it to be
combined with bSSFP imaging. Numerically optimized
adiabatic pulses were therefore used to design a T
2
Prep
for cardiovascular imaging at high magnetic field. The
energy efficiency of this optimized T
2
Prep
was established at 3T and compared to standard adiabatic
T
2
Prep. Finally, T
2
-prepared bSSFP
cardiovascular imaging and coronary MRA were
demonstrated in healthy volunteers.
