Intermediate field strength between 3 T and 7 T may provide significant signal-to-noise ratio improvement but with less radio frequency challenges. In this work in-vivo human brain images including anatomic images, angiography images and susceptibility weighted images have been acquired at a prototype 5 T whole body scanner using a 48 channel Tx-Rx array, and compared with those at 3 T commercial scanner. Significant signal-to-noise ratio improvement of 5 T has been shown while image homogeneity is still acceptable.
