(A) Conventional CT images show a lateral view of the tooth-bearing part of the left dentary. The arrow indicates an abnormal growth that sticks out from the surface of the tissue. (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 abnormal growth and adjacent tooth roots (arrowhead).

Dual-energy CT (DECT) was recently used by radiologists to diagnose a 63 million year-old Tyrannosaurus rex dinosaur, according to a recent abstract at the Radiological Society of North America. Dr. Charlie Hamm, a radiologist at the Charit√© University Hospital in Berlin, and his team used DECT to scan the dinosaur’s mandible, measuring¬†31.3 inches (79.5 centimeters) long and had a maximum thickness of 3.2 inches (8.1 cm).
