[Functional spiral CT of the larynx].
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.
