Comparative Study
Comparison of sonography and computed tomography as imaging tools for assessment of airway structures.
The aim of this study was to compare airway anatomic parameters as measured by sonography and computed tomography (CT). ⋯ The study shows that sonography can reliably image all of the structures visualized by CT, and in general, infrahyoid parameters agree well between the two modalities, as opposed to suprahyoid parameters, which may be affected by unintentional head extension.
