Key result
Magnetic resonance arthrogram offers better definition of labral tears compared with conventional MRI, especially when evaluating shoulder instability more than 2 weeks after injury.
Why the study?
Does magnetic resonance arthrogram improve accuracy and precision for evaluating labral tears after first-time shoulder dislocation compared to conventional MRI?
Does magnetic resonance arthrogram improve accuracy and precision for evaluating labral tears after first-time shoulder dislocation compared to conventional MRI?
Magnetic resonance arthrogram is more accurate than conventional MRI for evaluating labral tears when performed more than 2 weeks after a first-time shoulder dislocation.
Recent research shows that magnetic resonance arthrogram offers better definition of certain shoulder pathology, especially labral tears, compared with magnetic resonance imaging (MRI). Conventional MRI accuracy and precision deteriorate after 2 weeks, and few health delivery environments achieve MRI within 14 days of a shoulder dislocation. Moreover, further loss of MRI accuracy is time dependent. Although magnetic resonance arthrogram should be considered a first-line imaging study when evaluating shoulder instability more than 2 weeks after the patient's injury, one must also consider clinical value and cost-effectiveness.
