Abstract
Introduction:
We assessed the diagnostic accuracy of 3T magnetic resonance imaging in comparison with surgical exploration for detecting root avulsion in brachial plexus birth injuries.
Methods:
This retrospective cohort study describes a consecutive series of 18 infants with brachial plexus birth injuries born between January 2019 and May 2024 who had a surgical exploration of the plexus preceded by magnetic resonance imaging under the same general anaesthetic.
Results:
The overall diagnostic accuracy of magnetic resonance imaging for detecting root avulsion(s) of C5–T1 was 68%, with 67% sensitivity and 92% specificity. It has a ‘good’ diagnostic accuracy for detection of root avulsion, although only a ‘sufficient’ sensitivity.
Conclusion:
Although useful, magnetic resonance imaging in its current form cannot be solely relied upon for clinical decision-making in brachial plexus birth injuries.
Level of evidence:
IV
