Practical Considerations for the Evaluation of the Neuroforamina in Routine Spine Imaging at 3T. A Case Series

May 11, 2015 by
Pathologies of the neuroforamina are one of the most frequent indications for spine surgery. However, in standard MRI with axial and sagittal planes and relatively thick slices (>3 mm) the diagnostic information may be limited for proper evaluation of the nerve roots. Prof. Marc-André Weber et al. (University Hospital Heidelberg, Germany) share practical tips on […] [...]

An open bore MRI has the practical advantage of accommodating large or claustrophobic patients. Unfortunately, until the advent of the 1.5T MAGNETOM Espree, “open” was often synonymous with inferior image quality.
