Patient preparation

Position the patient supine in the  SENSE NeuroVascular 16 (or SENSE NeuroVascular 8 coil).

The shoulders must be tight against the coil and the shoulders should be relaxed, this is especially important when you use fat suppression.

Posterior Triangle

Red: Posterior Triangle; <br>Yellow: FOV bilateral Posterior Triangle The posterior triangle is the angle between the neck and shoulder and contains many anatomies such as nerves, vessels, lymph nodes and muscles. All the sequences are optimized for imaging the posterior triangle with a large FOV. This makes it possible to compare both sides.

Fat Suppression

Coronal: A small square shim volume at the junction gives the most homogeneous fat suppression. It has to be placed half in the thorax and half in the neck. Don't include too much lung.
