Radiologists use diagnostic imaging to non-invasively look inside the body to help determine the causes of an injury or an illness, and confirm a diagnosis. Providers use many imaging modalities to do so, including CT, MRI, X-ray, Ultrasound, PET and more.

Bone age assessments are commonly used to evaluate whether a child's skeletal development is consistent with their chronological age.
Chest CT findings reveal link between vertebral bone density, brain aging
Chest CT is routinely performed for things like lung cancer screening, coronary calcium assessment and pulmonary nodule surveillance, but the modality also can be used to extract additional information.
$AI spots difficult-to-detect femoral neck fractures$
AI model bests radiologists at spotting difficult-to-detect hip fractures
By highlighting subtle abnormalities that could otherwise be overlooked, an algorithm could potentially serve as an additional safety net when radiographic findings are indeterminate.
A cautionary tale for radiologists who use AI to rule out suspicious findings
Experts involved in the investigation suggest their experience should be considered by others who have integrated AI into their clinical workflows.
