To evaluate the need for additional magnetic resonance imaging (MRI) following ultrasound (US) in patients with shoulder pain and/or disability and to compare the accuracy of both techniques for the detection of partial-thickness and full-thickness rotator cuff tears (RCT).
In 4 years, 5,216 patients underwent US by experienced musculoskeletal radiologists. Retrospectively, patient records were evaluated if MRI and surgery were performed within 5 months of US. US and MRI findings were classified into intact cuff, partial-thickness and full-thickness RCT, and were correlated with surgical findings.
Additional MR imaging was performed in 275 (5.2%) patients. Sixty-eight patients underwent surgery within 5 months. US and MRI correctly depicted 21 (95%) and 22 (100%) of the 22 full-thickness tears, and 8 (89%) and 6 (67%) of the 9 partial-thickness tears, respectively. The differences in performance of US and MRI were not statistically significant (p = 0.15).
MRI following routine shoulder US was requested in only 5.2% of the patients. The additional value of MRI was in detecting intra-articular lesions. In patients who underwent surgery, US and MRI yielded comparably high sensitivity for detecting full-thickness RCT. US performed better in detecting partial-thickness tears, although the difference was not significant.
评估在肩部疼痛和/或功能障碍患者中，在进行超声（US）检查后是否需要额外进行磁共振成像（MRI）检查，并比较这两种技术在检测部分厚度和全层肩袖撕裂（RCT）方面的准确性。
在 4 年期间，5216 名患者由经验丰富的肌肉骨骼放射科医生进行了 US 检查。回顾性地，如果在 US 后 5 个月内进行了 MRI 和手术，则评估患者的病历。将 US 和 MRI 结果分类为完整的肩袖、部分厚度和全层 RCT，并与手术结果相关联。
275 名（5.2%）患者进行了额外的 MRI 检查。68 名患者在 5 个月内接受了手术。US 和 MRI 分别正确描绘了 22 个全层撕裂中的 21 个（95%）和 22 个（100%），以及 9 个部分厚度撕裂中的 8 个（89%）和 6 个（67%）。US 和 MRI 的性能差异无统计学意义（p=0.15）。
仅在 5.2%的患者中要求在常规肩部 US 后进行 MRI。MRI 的额外价值在于检测关节内病变。在接受手术的患者中，US 和 MRI 检测全层 RCT 的敏感性相当高。US 在检测部分厚度撕裂方面表现更好，尽管差异无统计学意义。
