Low et al took 320-slice CT scans of the larynxes of 46 people with severe asthma throughout the respiratory cycle. They decided that 23 (50%) had abnormal narrowing of the vocal cords during either inspiration or expiration, and in 9 (19%) the narrowing was severe. This is an experimental modality so the clinical implications are unclear, but it could conceivably evolve into a new test for vocal cord dysfunction, a comorbid condition frequently resulting in overtreatment with corticosteroids in many asthmatics.
