Thin-section spiral volumetric CT for the assessment of lobar and segmental bronchial stenoses.

Thin-section volumetric computed tomography (CT) was used to examine the lobar and segmental bronchi of five patients who had stenoses of these airways diagnosed by previous bronchography and/or bronchoscopy. Four of 23 lobar bronchi and 42 of 72 segmental bronchi were judged to be stenotic by CT. Our findings in this small group suggest that thin-section volumetric CT is a promising non-invasive technique that is likely to prove useful in the assessment of such stenoses in the future.
