Summary

This study looks at whether patients who take antiplatelet drugs (blood thinners) and have a minor head injury, but no other signs of brain bleeding, still need a CT scan. Current guidelines recommend a scan for these patients, but the evidence is weak. The study will follow 3,200 adults to see if skipping the scan is safe when no other risk factors are present.
