Prostate imaging is challenging at 7T due to its small size seated deeply inside the pelvic region. As such, both transmit receive performance of the RF coils are heavily challenged. We have recently developed a new paddle-shape Integrated Multi-modal Antenna with coupled Radiating structures (I-MARS) allowing an ensemble of eight elements to be placed tightly together among each other and closely to the imaging region. In the current work, we demonstrate optimized work-flow and in vivo imaging results using such an 8-element paddle I-MARS coil with an upgraded MAGNETOM 7T Plus system.
