Dynamic volumetric CT with wide-detector is becoming alternative examination to bronchoscopy in cases with persistent stridor or wheezing in children. The advantages of dynamic volumetric CT are rapid short examination time, no requirement of deep sedation and intubation, less need for patient cooperation, and extra-airway structure evaluation. It is essential to get adequate image quality at reduced radiation dose in dynamic volumetric CT. The teaching points of this presentation are; 1.The optimal scanning protocol of dynamic volume scan with proper radiation dose for each patient 2.Techniques to reduce various artifacts. 3.Four-dimensional reconstruction from volumetric CT data.  

1.Principles of dynamic volume scan 2.How to get adequate image quality at the optimal reduced radiation dose for each patient 3.Techniques for reducing various artifacts 4.How to reconstruct 4D-CT images
