Highfield MRI at 7T inherently offers higher signal-to-noise and enhanced soft tissue contrasts when compared to 1.5T or even 3T MRI, which might improve image quality in selected imaging applications like high-resolution cardiac MRI in humans. To push cardiac MRI at 7T another step further, a number of artifacts and imaging constraints related to 7T transmit/receive problems have to be addressed first. Additionally, protocols already established for 1.5T and 3T cardiac imaging have to be evaluated. This study presents two RF coil concepts to tackle some transmit/receive issues and evaluates established cardiac protocols which have been modified for application at 7T.
