The concept of simultaneous excitation and acquisition (SEA) introduced with the SWIFT technique enables MRI of samples with very short T2 also under B1 constraints. Within this framework we suggest a number of improved sampling strategies, addressing reconstruction stability, SNR, and artefacts related to pulse errors. High-quality SEA images of short-T2 samples acquired at a bandwidth of 100 kHz are presented.
