A new propeller sequence has been implemented as a complement to existing T2-w and T2 FLAIR techniques. Based on the classical Spin-Echo sequence, the aim was to produce an image contrast before and after Gd administration that it familiar to the radiologists, while overcoming artifacts from flow and motion. Being a T1-w propeller acquisition, off-resonances from the signal-intense fat manifests as a swirly bright structures instead of a simple shift, why high bandwidths should be used, in particular at 3T.
