non-accidental trauma
Intentional injury to a child, requiring careful radiological evaluation for characteristic patterns and dating of injuries.
Full Definition
Non-accidental trauma (NAT) refers to intentional injuries inflicted upon children, which presents unique challenges in pediatric radiology. Radiologists play a crucial role in identifying suspicious injury patterns, dating fractures, and documenting findings that may indicate abuse. Common radiological signs include metaphyseal corner fractures, spiral fractures in non-ambulatory children, multiple fractures in different stages of healing, and subdural hematomas. The evaluation requires specialized knowledge of normal childhood development and injury patterns to distinguish accidental from intentional trauma.
Usage
Usage note: Use sensitivity when documenting; avoid abbreviating as NAT in patient-facing documents.
