Summary

This study looks at how doctors decide to use brain CT scans for people with mild head injuries in emergency rooms. Many CT scans come back normal, exposing patients to unnecessary radiation and increasing costs. Researchers will analyze data from 2,500 adults across Italy to understand differences between hospitals, validate decision-making tools, and develop a model to predict recovery.
