The effect of iterative reconstruction on computed tomography assessment of emphysema, air trapping and airway dimensions
European Radiology, 05/31/2012
Mets OM et al. – The evaluated iterative reconstruction (IR) algorithm significantly influences quantitative CT measures in the assessment of emphysema and air trapping. However, the E/I–ratioMLD as a measure of CT air trapping, as well as the airway measurements, is unaffected by this reconstruction method. Quantitative CT of the lungs should be performed with careful attention to the CT protocol, especially when iterative reconstruction is introduced.
