Case Discussion
Non-accidental injury (NAI) is a very serious and stressful aspect of pediatric medicine.
The radiologist plays a crucial role in the assessment process after the concern is raised by the responsible clinician.
Most institutions have imaging protocols for NAI, adherence to which is important.
Certain injuries, such as posterior rib and metaphyseal corner fractures are highly indicative, especially if in conjunction with intracranial hemorrhage.
