MR imaging techniques of the larynx,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.

General discussion, of coils results in a considerable improvement of the signal-to-noise ratio of the laryngeal image. It is also possible to obtain high signal resolution images with a field of view as small as possible and with a minimal slice thickness, which is necessary to demonstrate delicate laryngeal structures.

General aspects of MR imaging,ectromagnetic energy . MRI was developed in 1973, thanks to the work of Paul C. Lauterbur, who published initial experiments on the use of MR to generate an image . Since that time, progress has been very rapid and has enabled the adoption of MR imaging as a standard procedure in medical diagnosis.

MR findings of cartilage invasion by laryngeal cancer. Value in predicting outcome of radiation theuent risk of tumor recurrence. Cartilage invasion seen at MR imaging might therefore shift the preference to partial laryngectomy as the initial treatment for small glottic tumors. Alternatively, radiation therapy alone would appear to require stringent follow-up to detect possible recurrence.
