Diffusion tensor imaging (DTI)

Diffusion tensor imaging (DTI) is an advanced MRI technique that tracks the movement of water molecules to map the health of white matter tracts. In a healthy brain, water moves along these "wires" in a single, efficient direction. In an injured brain, the water diffuses outward, indicating a breach in structural integrity and frayed neural connections. Standard MRIs often fail to detect these microscopic changes, making DTI essential for seeing "invisible" injuries.

Bottom Line: DTI is the gold-standard scan used in Q-Collar clinical trials to provide objective proof that the device helps better protect the structure of the brain over a full season of competitive play.
