Summary

This study looked back at 858 CT scans done in an adult emergency room over 28 days in 2024. The goal was to see how many were truly justified by official guidelines or by changing how a patient was treated. The researchers hope to find out if too many CT scans are being done, which can expose patients to radiation and increase costs.

What this could lead to
