High-field MRI at 7 Tesla inherently offers high signal-to-noise (SNR) and enhanced soft tissue contrasts when compared to 1.5 T or even 3 T MRI, which might improve image quality in selected imaging applications in humans. The increased SNR is in particular potentially beneficial for high-resolution cardiac MRI. In order to exploit the full potential for cardiac MRI at 7 T, a number of artifacts and imaging constraints related to 7 T have to be overcome. In this study four volunteers were imaged with a flexible 8-channel transmit/receive body coil to evaluate potential advantages and disadvantages specifically associated with cardiac MR imaging at this high field strength.
