Cardiac functional MRI has been established in clinical practice on 1.5T and 3T scanners; nevertheless, the capabilities of ultra-high field (UHF) MRI have not been fully exploited, which are expected to significantly improve image quality and provide information not obtainable at lower-field MRI. Despite its advantages, UHF MRI is challenging due to a number of technical issues, especially B1 and B0 inhomogeneities. In this study, we provide preliminary results of using a multi-channel transceiver modular coil and a dielectric pad towards optimizing UHF cardiac functional MRI by improving image quality and minimizing imaging artifacts.
