PURPOSE
To determine whether magnetic resonance (MR) arthrography of the elbow can demonstrate precisely an ulnar collateral ligament (UCL) abnormality in the throwing athlete.
MATERIALS AND METHODS
Forty college-level and professional throwing athletes (age range, 18-40 years) underwent saline-enhanced MR arthrography of their injured elbows. MR findings were compared with the surgical findings.
RESULTS
Saline-enhanced MR arthrography was positive in 24 of 26 individuals with UCL tear confirmed at the time of surgery. Eighteen (95%) of 19 complete UCL tears and six (86%) of seven partial UCL tears were diagnosed with MR arthrography. Two false-negative findings and no false-positive findings were obtained.
CONCLUSION
Saline-enhanced MR arthrography of the elbow is a new application of a previously described technique used in the shoulder. It is useful for demonstration of subtle and gross UCL abnormalities in the throwing athlete.
目的
确定肘部磁共振（MR）关节造影能否精确显示投掷运动员的尺侧副韧带（UCL）异常。
材料与方法
40名大学水平和职业的投掷运动员（年龄范围18 - 40岁）对其受伤的肘部进行了生理盐水增强MR关节造影。将MR检查结果与手术结果进行比较。
结果
在26例手术时确诊为UCL撕裂的个体中，24例生理盐水增强MR关节造影呈阳性。19例完全UCL撕裂中的18例（95%）和7例部分UCL撕裂中的6例（86%）通过MR关节造影得以诊断。获得了2例假阴性结果且无假阳性结果。
结论
肘部生理盐水增强MR关节造影是一种先前用于肩部的技术的新应用。它有助于显示投掷运动员细微和明显的UCL异常。
