Application of surface coils to MR anatomy of the larynx.

The magnetic resonance (MR) scans of 10 patients with normal larynges were compared with cryomicrosections of two injected cadaver specimens. The MR images were obtained with a solenoid surface coil and high-resolution technique that provided images 4 mm thick displayed on a 256 X 256 matrix. The improved signal-to-noise ratio of the surface coil allowed a detailed study of normal anatomy in the axial, coronal, and sagittal planes.
