Synopsis

Large field-of-view imaging of spine in ultra-high field 5.0T magnetic resonance imaging system is achieved with RF hardware design of an 8-channel volume transmit coil and a dedicated posterior spine array of 48 receive channels. The axial coverage and transmit homogeneity allow the use of refocusing pulses under specific-absorption ratio limits by safety regulations. Consequent high-resolution fast spin echo clinical images are acquired and compared with results on a commercial 3.0T scanner.
