Magnetic resonance neurography (MRN) has been increasingly used to evaluate brachial plexopathy. However, MRN is limited by the lack of relative contrast between nerves and their surrounding tissues. As an alternative to MRN, T2-SPACE has been proposed as a black-blood technique that permits more direct visualization of the brachial plexus; however, it has similar limitations. A preliminary study demonstrated that T2-weighted DANTE-SPACE outperformed SPACE and might be a potential alternative for the visualization of the brachial plexus. In this study, we hypothesized that T2-weighted DANTE-SPACE would address the above issue due to its superior blood flow suppression.
