Journal of Computer Assisted Tomography, 10/12/09
Achenbach T et al. – Using a special technique such as IBM to account for computed tomography's blurring effect in assessing airway wall thickness had the greatest impact on correct quantification. The visual impression and the automatic quantification using the FWHM technique improved marginally by decreasing the voxel size to less than 0.195 × 0.195 × 0.8 mm. The FWHM technique as a model for visual quantification is not reliable for airway wall thicknesses less than 1.5 mm.
