SSFP cardiac imaging at 3T suffers from off-resonance artifacts and has limited readout duration. Wideband SSFP can solve these problem by providing an efficient scheme for acquiring SSFP images with long readouts, which will allow the high SNR of 3T SSFP to be translated into higher spatial and temporal resolution. In this work we implemented wbSSFP for 3T cardiac imaging in both PG-gated 2DFT imaging and real-time imaging with a 3.2ms long three-echo EPI readout. A significant improvement over conventional SSFP was observed in both cases.
