B1 field inhomogeneity become increasingly problematic in ultrahigh-field (UHF) strengths (7T). Parallel transmition is introduced to reduce B1 inhomogeneity. In abdominal imaging region like Kidney or spine shows more structural visibility after performing RF shimming on individual channels of the 8Tx/32Rx abdominal RF coil. The T2* maps also reflect the more homogeneous signal distribution after RF shim perfomance.
