Comparison of Radiographic, Ultrasound, and Magnetic Resonance Imaging for the Detection of Retained Stingray Barb: A Cadaveric Study

IntroductionStingray envenomations are a common marine animal injury for which it is important to identify and remove retained barbs prevent secondary infection. The optimal imaging modality in stingray foreign body detection not well characterized the existing literature. In this study, we compared accuracy of plain radiography, ultrasound, magnetic resonance (MRI) detecting human foot ankle.MethodsThis cadaveric study included 1:1 randomization presence or absence 24 sample injuries ankle specimens. Physicians trained emergency medicine radiology performed ultrasound examinations on each specimen interpreted barb. Participants also x-ray images same manner. MRI scans were separately by musculoskeletal attending. Data analyzed using McNemar’s test.ResultsThe 19 participants 14 (74%) 5 (26%) radiology. Forty-seven percent residents, 42% faculty, 11% fellows. X-ray was associated with highest sensitivity 94% identification barb, followed (83%) (70%). specificity 100%, (98%) (73%).ConclusionsRetained can lead infection after envenomation. specimens, demonstrated sensitivity, specificity, lower specificity.
