Application of Three-dimensional Reconstruction in Esophageal Foreign Bodies

Ji-Min Chang et al. Korean J Thorac Cardiovasc Surg. 2011 Oct.

Abstract

This study was conducted to investigate the clinical application of three-dimensional (3D) reconstructed computed tomography (CT) images in detecting and gaining information on esophageal foreign bodies (FBs). Two patients with esophageal FBs were enrolled for analysis. In both cases, 3D reconstructed images were compared with the FB that was removed according to the object shape, size, location, and orientation in the esophagus. The results indicate the usefulness of conversion of CT data to 3D images to help in diagnosis and treatment. Use of 3D images prior to treatment allows for rapid prototyping and surgery simulation.

Keywords: Computed tomography; Esophageal foreign body; Esophageal surgery.
