Abstract
Conclusion: The rendering strategy sometimes induces misunderstanding of the image. We demonstrated a more accurate image of the bony groove of the reuniting duct using three-dimensional (3D) cone beam CT image, which was less affected by artifacts created by the rendering effect. Objective: To obtain a suitable image of the groove of the reuniting duct for future morphological study. Materials and methods: The grooves of reuniting ducts in 10 healthy human subjects were analyzed by cone beam CT in comparison with a cadaver study. Results: We could obtain more accurate 3D CT images of the bony groove in human subjects by checking the landmarks of 3D CT images.
