MR imaging techniques of the larynx

Abstract

Coils which are placed close to the body nearest the organ of interest, so-called surface coils, are a welcome addition in the MR imaging of the laryngeal area [1]. The adjacency of the receiving antenna to the laryngeal area and its small sensitive volume produces a larger signal-to-noise level, at the cost of the magnitude and uniformity of the imaged volume. Such coils enable one to obtain high resolution, thin section images using relatively short acquisition times. With the use of the surface coil it is possible to obtain high resolution images with the minimum technical field of view. A shorter scanning time will reduce motion artifacts due to coughing and swallowing.
