CT Uncovers Bone Disease in Tyrannosaurus Rex Jaw (IMAGE)
Caption
CT reconstructions of the tooth-bearing part of the left dentary. (A) Reconstruction of the conventional CT images in lateral view showing well-preserved anatomical structures such as the replacement teeth. The arrow indicates the focal exophytic mass—the abnormal growth that sticks out from the surface of the tissue—on the ventral surface at the level of the 3rd to 5th tooth roots. (B) The DECT-based calcium material map shows a homogeneous mineral distribution, while (C) the fluorine material map shows significant mineral accumulation in the center of the exophytic mass and adjacent tooth roots (arrowhead).
