By comparing CT scans of the larynx with anatomical sections in the horizontal plane as well as by examining patients, a method of investigation especially aimed at phoniatric questions has been worked out: CT scans are performed every 4 mm parallel to the vocal cord plane using a center of 50 HE and a window of 350 HE. The examination is done during regular respiration and if required can also be performed during phonation when producing the vowel /u/. Using this technique the laryngeal structures of clinical relevance can be demonstrated with the help of at least 10 scans. It requires little time and the radiation exposure for the patient is minimal. The accuracy of CT measurements corresponds excellently to the anatomical features. Allowing an exact evaluation of anomalies of the larynx in shape and position, CT essentially improves phoniatric diagnostics.
通过将喉部的CT扫描与水平面的解剖切片进行比较以及对患者进行检查，已经制定出一种特别针对嗓音医学问题的调查方法：使用50HE的中心值和350HE的窗宽，每隔4毫米平行于声带平面进行CT扫描。检查在正常呼吸时进行，如有需要，也可在发元音/u/时发声期间进行。使用这种技术，借助至少10次扫描可以显示具有临床相关性的喉部结构。它所需时间少，患者的辐射暴露量最小。CT测量的准确性与解剖特征非常吻合。CT能够对喉部在形状和位置上的异常进行精确评估，从根本上改善了嗓音医学诊断。
