Radiation Dose and Risk in the Radiological Investigation of Suspected Non‐Accidental Injury (NAI)

Journal of Medical Radiation Sciences, Volume 73, Issue S2, Page S92-S100, April 2026.
This study is a retrospective analysis of 362 skeletal surveys performed over a 5‐year period for children under 5 years of age for suspected non‐accidental injury. We present effective dose data and the associated risks of radiation exposure for initial and follow‐up examinations.
