We introduce a novel multiple TR bSSFP sequence for positive contrast imaging. Using simulated annealing, the sequence has been designed for a spectral profile that has stopbands over both fat and water resonances. This enables simultaneous water and fat suppression, which improves contrast without requiring a second acquisition, as with for example, the PARTS (Positive Contrast with Alternating Repetition Time SSFP) technique.
