Diagnosis: Open MRI Image Guided Injection of Anterior Scalene Muscle

Animation: Open MR image guided injection of the anterior scalene muscle.

In the coronal image (A), the arrow indicates a darkened area caused by the injectate within the anterior scalene muscle.

In the axial image (B), the titanium needle is seen passing into the anterior scalene muscle. The injectate has expanded the muscle, however the failure of injectate to flow in to the more posterior portions of the muscle suggests fibrosis within the muscle.
