Core Tip
Core Tip: The capabilities of ultra-high-field magnetic resonance imaging (MRI) have not been fully exploited in cardiac functional imaging. In this study, we provide results from phantom and in vivo scans using a multi-channel transceiver modular coil to optimize 7T cardiac MRI functional imaging without the need for conducting B1 shimming or subject-specific system tuning. The results showed that improved regional and global cardiac functional imaging can be achieved at 7T MRI through simple scan set-up adjustment and imaging parameter optimization, which would allow for more streamlined and efficient ultra-high-field cardiac MRI with access to more information and details compared to lower-field imaging.
