avoiding exposure of children to unnecessary radiation associated with other types of diagnostic imaging like computed tomography (CT) scans.1

With musculoskeletal MRI, a Medicare-eligible scan is performed “following radiographic examination”.1

Plain x-ray, rather than MRI, remains the gold standard for diagnosing most musculoskeletal conditions in children, and we report two cases where the initial use of MRI rather than x-ray led to a delay in diagnosis.

First, an 11-year-old girl was investigated for a 3-month history of left knee pain and locking. An ultrasound and MRI scan (Box 1, A) were performed, although an x-ray was not done. As no cause for the symptoms was identified on the ultrasound or MRI, the patient was referred to an orthopaedic surgeon, who requested an x-ray (Box 1, B).
