Work in progress: NMR anatomy of the larynx and tongue base.
The normal anatomy of the larynx and base of the tongue as seen on nuclear magnetic resonance (NMR) images was studied. Scans of normal volunteers were obtained using a 3.5 kilogauss (0.35 T) superconductive magnet and a 3.0 kilogauss (0.3 T) permanent magnet. The NMR images were compared with images obtained by CT and with anatomical sections of these regions. Although resolution is not comparable to that seen on scans obtained with modern CT equipment, there are some advantages to NMR imaging. These include availability of multiple projections, ease of identifying blood vessels and differentiating them from lymph nodes, and the possibility of improved tissue specificity.
