Synopsis

Ultra-high field magnetic resonance imaging (MRI) of human brain with high resolution has been increasing used for clinical and research applications. Due to RF transmit homogeneity and specific absorption issues, clinical use of ultra-high field MRI were limited. In this work, a local quadrature birdcage/48-channel receiver coil assembly was designed and evaluated on a novel whole body 5T MRI scanner. The coil at 5T showed improved SNR, higher parallel acceleration capability and improved detection in vessel wall imaging compared to a 32-channel coil at a 3T commercial scanner.
