Spatial resolution has typically been prioritized at the expense of temporal resolution in the setting of dynamic contrast-enhanced breast MRI. In this work, we evaluated the use of compressed sensing (CS) with intermittent fat suppression for improved temporal resolution by comparing quality of fat suppression and overall image quality between a sequence accelerated using CS to one without CS.
