Three-dimensional Optical Surface Imaging as a Diagnostic Tool in Pectus Excavatum

Pectus excavatum (PE) is the most common anterior chest wall deformity. Currently, a chest radiography (CR) or Computed Tomography (CT) scan is acquired to determine and objectify pectus severity using the Haller Index. Alongside other determinants, the Haller Index value is used in the proces of clinical decision making and determine surgical candidacy. However, cross-sectional imaging based calculation of the Haller Index implies exposure to ionizing radiation that should be limited at all times to diminish the cumulative long-term risks of malignancy. Especially in pectus patients that often concerns children. Three-dimensional (3D) optical surface imaging offers a non-invasive, radiation-free alternative that may be used to obtain thoracic measures and determine pectus severity. However, for 3D images/scans to be used as a diagnostic tool in the proces of clinical decision making and determine surgical candidacy, its diagnostic accuracy should be evaluated. This will be investigated utilizing a pilot study design as no prior accuracy studies are available.
