Volume-monitored chest CT: a simplified method for obtaining motion-free images near full inspiratory and end expiratory lung volumes.

Background: Lung inflation and respiratory motion during chest CT affect diagnostic accuracy and reproducibility.

Objective: To describe a simple volume-monitored (VM) method for performing reproducible, motion-free full inspiratory and end expiratory chest CT examinations in children.

Materials And Methods: Fifty-two children with cystic fibrosis (mean age 8.
