Neurogenic thoracic outlet syndrome is often caused by
brachial plexus compression in the scalene triangle and
costoclavicular space. As such, scalene muscles are the
principle target for intramuscular diagnostic and
therapeutic injections. MRI guidance offers
cross-sectional imaging with high soft tissue contrast,
absence of ionizing radiation, and the ability to
visualize injectants without a contrast agent. We
describe a technique of 3 Tesla MR-guided scalene muscle
injections, which combines high accuracy, a favorable
safety profile, the absence of ionizing radiation, and
the ability to accurately visualize the injectant
without the need of a contest agent.
