Improvements in Cardiac MRI at 3T Using High Permittivity Materials

Wyger M. Brink¹, Andrew Webb¹

High permittivity pads are shown to improve the transmit efficiency, B1 homogeneity and CNR in bSSFP imaging significantly, resolving RF related artifacts commonly encountered in functional cardiac imaging at 3T. The proposed solution is shown to outperform dual-transmit RF shimming.
