 +Fat saturation can be tricky in the cervical/plexus area due the uneven anatomy, presence of microchips, and large FOV's required.

 +  * Use Dixon techniques for fat saturation (Dixon, FLEX, IDEAL)
 +  * SPAIR/SPECIAL techniques may be a bit more homogenous if available
 +  * Manually shim to the area around the thoracic inlet
 +  * Position and scan close the isocenter
 +  * Use the smallest appropriate FOV
