Summary

This study tested whether a new ultra low-dose CT scanner can find bone fractures as well as standard X-rays, but with less radiation. Over 500 emergency patients with suspected breaks in the spine, pelvis, or limbs were scanned using both methods. The goal was to see if the low-dose scanner is accurate enough to use in place of regular X-rays.
