Vascular Thoracic Outlet Syndrome: Protocol Design and Diagnostic Value of Contrast-Enhanced 3D MR Angiography and Equilibrium Phase Imaging on 1.5- and 3-T MRI Scanners

American Journal of Roentgenology, 04/24/2012

Contrast–enhanced 3D MRA using provocative arm positioning allows excellent imaging of the arteries and veins on both sides and thus provides a noninvasive imaging alternative to digital subtraction angiography in patients with suspected vascular thoracic outlet syndrome (TOS). Contrast–enhanced 3D MRA is also an ideal imaging modality for postsurgical follow–up for identifying restenosis or residual vascular compression. However, all imaging studies, including the contrast–enhanced 3D MRA protocol described here, should be treated as complementary tests for the diagnosis of TOS.
