Imaging the brachial plexus can be challenging due to the large variations in the B0 and transmit B1 fields in the area of the neck and shoulders. These variations can result in poor background tissue and fat suppression as well as reduction in the received signal from the nerves. We wanted to study if the application of high permittivity pads could increase signal/contrast in plexus brachialis imaging. By applying the pads the signal intensity of the nerves increased from 25 to 50 while the background signal stays similar resulting in a greater contrast of the brachial plexus.
