A mechanism based on spatiotemporal encoding is exploited to add spectral selectivity to a pair of slice-selective frequency-swept pulses. The SPEN-based SPSP selectivity is used for fat suppression in spin-echo imaging. It does not require fast oscillating gradients and provides high-quality slice profiles. It can also be used to acquire images for two chemical species simultaneously. These concepts are illustrated with phantom experiments at 7T. Examples of fat suppression and water/fat imaging are also shown for breast imaging of human volunteers at 3T.
