Assessment of the reuniting duct by three-dimensional CT rendering.
CONCLUSIONS
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.


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.
