Objectives: The purpose of our study was to determine whether a three-dimensional (3D) isotropic resolution fast spin echo sequence (FSE-cube) has similar image quality and diagnostic performance as a routine MRI protocol for brachial plexus evaluation in volunteers and symptomatic patients at 3.0 T. Institutional review board approval and written informed consent were guaranteed. Methods: In this prospective study FSE-cube was added to the standard brachial plexus examination protocol in 8 patients (mean age, 50.2 years) with brachial plexus pathologies and in 6 volunteers (mean age, 54 years). Nerve visibility, tissue contrast, edge sharpness, image blurring, motion artefact and acquisition time were calculated for FSE-cube sequences and for the standard protocol on a standardised five-point scale. The visibility of brachial plexus nerve and surroundings tissues at four levels (roots, interscalene area, costoclavear space and axillary level) was assessed. Results: Image quality and nerve visibility were not significantly different with FSE-cube and the standard protocol (p > 0.05). Acquisition time was statistically and clinically significantly shorter with FSE-cube (p < 0.05). Pathological findings were seen equally well with FSE-cube and standard protocol. Conclusion: 3D FSE-cube provided similar image quality in a shorter acquisition time and enabled excellent visualisation of brachial plexus anatomy and pathology in any orientation, regardless of the original scanning plane. |
