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.
