Imaging of the larynx by computed tomography has reached a new quality through spiral CT. Its significance for evaluation of vocal cords function is examined with 10 patients with glottic tumours before, during and after radiation therapy. The spiral CT procedure which complements laryngoscopy is described: Gantry tilt 10 degrees caudal, two spiral CT starting at the cricoid cartilage with 3 mm slice thickness and pitch 1, one with flat breathing and one with "1" phonation; overlapping reconstruction with large zoom factor, secondary reconstruction image reformating.
通过螺旋CT，喉部的计算机断层成像质量达到了新高度。对10例声门肿瘤患者在放疗前、放疗期间及放疗后进行检查，以评估螺旋CT在声带功能评估方面的意义。文中描述了作为喉镜检查补充手段的螺旋CT操作过程：机架向尾侧倾斜10度，从环状软骨开始进行两次螺旋CT扫描，层厚3毫米，螺距1，一次在平静呼吸时进行，一次在发“1”音时进行；采用大缩放因子进行重叠重建，对二次重建图像进行重新格式化。
