Figure 2. (A) A midline sagittal image from the dynamic magnetic resonance imaging in a patient with pectus carinatum chest is shown before the balloon brace is insufflated; (B) with sufficient insufflation of the balloon, the chest is made flat. This level of correction corresponds to the desired target of chest correction; (C) with extreme insufflation, the pectus carinatum chest can be converted to a pectus excavatum chest
