Pectus excavatum (PE) and pectus carinatum (PC) are the most frequent chest wall deformities in humans. They are usually clinically recognized in early childhood or adolescence, with aggravation during the pubertal growth spurt. PE is a depression of the anterior chest wall, most frequently involving the lower sternum. In this study we use simultaneously compared chest CT, MRI, and 3D scanning fro both PE and PC assessment . The aim of this study is to compare a standard protocol using chest CT to a non-irradiant protocol with 3D scanning and MRI. The primary endpoint was to assess the inter observer concordance and the correlation between the HI (Haller Index) evaluated with MRI and the EHI (External Haller index) evaluated with 3D scanning. The secondary endpoints were to assess the concordance with chest CT the variation of the HI evaluated in inspiration and expiration with MRI and also the correction index (CI) between chest CT and MRI in the PE group, .
