Objective: This study was conducted to gather basic information of 3D CT in detecting and gaining information of esophageal foreign body (FB) models.
Materials and Methods: The chest model was made using PVC bottle, rubber balloon and plaster. Fish bone, Persimmon stone were used to mimic foreign bodies of esophageal model. The foreign body models were inserted into the balloon removing air from it and the balloon was sealed. The esophageal FB model was inserted into the chest model. The remaining space in the chest model was filled with fish paste and water to simulate soft tissue around esophagus. CT of chest model was reconstructed three-dimensionally by Rapidia software to make images of foreign body models. The axial CT, MPR image and VOI image were compared with real foreign body materials as to shape, size, location and orientation.
Results: Esophageal FB models were easily made. CT data gave good 3D images and showed realistic foreign body materials.
Conclusion: The results indicate the usefulness of 3D CT technique to help in diagnosis of esophageal foreign body models.
