FAQs

What is MRI Thoracic Outlet Dynamic?

MRI Thoracic Outlet Dynamic is an advanced MRI examination that evaluates the thoracic outlet—the space between the neck and shoulder where the nerves and blood vessels pass. It assesses these structures in different arm positions to detect dynamic compression.

Why is MRI Thoracic Outlet Dynamic performed?

This examination is performed to diagnose or evaluate Thoracic Outlet Syndrome (TOS), including nerve compression (neurogenic TOS), arterial compression, venous compression, congenital abnormalities, trauma-related changes, and other conditions affecting the thoracic outlet.

Which structures are evaluated during this examination?

The examination evaluates the brachial plexus nerves, subclavian artery, subclavian vein, muscles, clavicle, first rib, cervical ribs, surrounding soft tissues, and other structures within the thoracic outlet.

Can MRI Thoracic Outlet Dynamic detect blood vessel compression?

Yes. The examination can demonstrate compression or narrowing of the subclavian artery and subclavian vein, especially when the arms are placed in positions that trigger symptoms.

What is the difference between MRI Thoracic Outlet Dynamic and a routine MRI?

A routine MRI is usually performed in a neutral position, whereas MRI Thoracic Outlet Dynamic includes specialized imaging during arm movement or elevation to detect positional compression that may not be visible on routine imaging.
