No reported data demonstrate the usefulness of magnetic resonance arthrography of the shoulder in children.
To evaluate the sensitivity, specificity and accuracy of MR arthrography in the assessment of superior labral anteroposterior (SLAP) tears of the shoulder, Bankart-type injuries and Hill-Sachs lesions in children as compared to arthroscopy.
We retrospectively interpreted 66 MR arthrograms of the shoulder and compared them with surgical findings. Assessment included evaluation of the osseous structures, labral-ligamentous complex and determination of skeletal maturity. We calculated sensitivity, specificity and accuracy and compared sensitivity and specificity between skeletally mature and immature children.
MR arthrography demonstrated a sensitivity, specificity and accuracy of 88%, 98% and 94%, respectively, for depiction of SLAP tears; 94%, 92% and 94% for detection of Bankart-type injuries; and 100%, 94% and 97% for diagnosing Hill-Sachs lesions. There was no statistical difference between the skeletally immature and skeletally mature groups.
There is no significant difference in the diagnostic accuracy of MR arthrography in skeletally immature versus skeletally mature children. MR shoulder arthrography is an effective method for the detection of labral and bone pathology.
目前尚无研究数据表明磁共振肩关节造影术在儿童中的应用价值。
评估磁共振肩关节造影术在评估儿童盂唇前后向（SLAP）撕裂、Bankart 型损伤和 Hill-Sachs 病变方面的敏感性、特异性和准确性，并与关节镜检查结果进行比较。
我们回顾性分析了 66 例肩关节磁共振关节造影检查结果，并与手术结果进行了比较。评估内容包括骨结构、盂唇-韧带复合体的评估和骨骼成熟度的判断。我们计算了敏感性、特异性和准确性，并比较了骨骼成熟和未成熟儿童的敏感性和特异性。
磁共振肩关节造影术在显示 SLAP 撕裂方面的敏感性、特异性和准确性分别为 88%、98%和 94%；检测 Bankart 型损伤的敏感性、特异性和准确性分别为 94%、92%和 94%；诊断 Hill-Sachs 病变的敏感性、特异性和准确性分别为 100%、94%和 97%。骨骼未成熟和成熟组之间无统计学差异。
磁共振肩关节造影术在骨骼未成熟和成熟儿童中的诊断准确性无显著差异。磁共振肩关节造影术是一种检测盂唇和骨病变的有效方法。
