Abstract
Objectives
To assess the contribution of whole-body magnetic resonance imaging (WBMRI) and bone scintigraphy (BS) in addition to skeletal survey (SS) in detecting traumatic bone lesions and soft-tissue injuries in suspected child abuse.
Methods
In this prospective, multicentre, diagnostic accuracy study, children less than 3 years of age with suspected physical abuse were recruited. Each child underwent SS, BS and WBMRI. A blinded first review was performed in consensus by five paediatric radiologists and three nuclear medicine physicians. A second review investigated discrepancies reported between the modalities using a consensus result of all modalities as the reference standard. We calculated the sensitivity, specificity and corresponding 95% confidence interval for each imaging modality (SS, WBMRI and BS) and for the combinations [SS + WBMRI] and [SS + BS].
Results
One hundred seventy children were included of which sixty-four had at least one lesion. In total, 146 lesions were included. The sensitivity and specificity of each examination were, respectively, as follows: 88.4% [95% CI, 82.0–93.1] and 99.7% [95% CI, 99.5–99.8] for the SS, 69.9% [95% CI, 61.7–77.2] and 99.5% [95% CI, 99.2–99.7] for WBMRI and 54.8% [95% CI, 46.4–63.0] and 99.7% [95% CI, 99.5–99.9] for BS. Sensitivity and specificity were, respectively, 95.9% [95% CI, 91.3–98.5] and 99.2% [95% CI, 98.9–99.4] for the combination SS + WBMRI and 95.2% [95% CI, 90.4–98.1] and 99.4% [95% CI, 99.2–99.6] for the combination SS + BS, with no statistically significant difference between them.
Conclusion
SS was the most sensitive independent imaging modality; however, the additional combination of either WBMRI or BS examinations offered an increased accuracy.
Key Points
• SS in suspected infant abuse was the most sensitive independent imaging modality in this study, especially for detecting metaphyseal and rib lesions, and remains essential for evaluation.
• The combination of either SS + BS or SS + WBMRI provides greater accuracy in diagnosing occult and equivocal bone injuries in the difficult setting of child abuse.
• WBMRI is a free-radiation technique that allows additional diagnosis of soft-tissue and visceral injuries.
