Chest Wall Disorder
Conditions
Brief summary
Recently, three-dimensional scanning of the torso has been proposed as an alternative for two-view chest radiographies and computed tomography to determine the severity of pectus excavatum without exposure to ionizing radiation. The range of three-dimensional scanning systems is broad with even varying systems being used within hospitals. Most of these scanning systems have been validated for accuracy and reproducibility, no comparison between these systems is known. In addition, severity measures of pectus excavatum, as well as other research outcomes, surgical planning techniques, and analysis methods are based on a single imaging system. It is subsequently essential to determine whether different imaging systems can be used interchangeably regarding accuracy and reproducibility. The aim of this study was to assess the reproducibility and accuracy between three commonly used three-dimensional scanning systems.
