Dual-energy CT scans of T-Rex reveal fossil's secrets
Using dual-energy CT (DECT), researchers have diagnosed bone disease in the fossilized jaw of a Tyrannosaurus rex named Tristan Otto, according to research presented this week at RSNA 2021. The work shows how DECT can be a noninvasive tool for paleontologists to investigate fossils.
