To evaluate magnetic resonance (MR) findings of surgically proved peroneal tendon tears.
MR images, medical records, and surgical findings were retrospectively reviewed in the cases of 12 patients who underwent surgery because of suspected peroneal tendon tear (14 tendons). Sagittal and oblique axial T1-weighted spin-echo and T2-weighted fast spin-echo images were obtained in all patients.
At surgery, isolated peroneus longus tendon tears were seen in four patients, isolated peroneus brevis tendon tears in five, and both peroneus brevis and peroneus longus tendon tears in two. When correlated with surgical findings, findings at MR imaging were correct in 12 tendons. Findings were false-positive in two patients and false-negative in one, who underwent surgery anyway because unrelated abnormal MR findings were present. The most common MR finding was increased intra-substance signal intensity on T1- and T2-weighted images (11 tendons), in linear or rounded areas on oblique axial images (n = 11) and in linear areas along the longitudinal axis of the tendons on sagittal images (n = 7). Tendon distortion was noted in severe cases (five tendons). The most frequent surgical finding was a longitudinal tendon tear (split) (10 tendons).
MR imaging enabled detection of peroneus brevis and peroneus longus tendon tears.
评估经手术证实的腓骨肌腱撕裂的磁共振（MR）表现。
回顾性分析12例因疑似腓骨肌腱撕裂而接受手术的患者（14条肌腱）的MR图像、病历及手术结果。所有患者均获得矢状位和斜轴位T1加权自旋回波图像及T2加权快速自旋回波图像。
手术中，4例患者可见孤立的腓骨长肌腱撕裂，5例为孤立的腓骨短肌腱撕裂，2例同时存在腓骨短肌腱和腓骨长肌腱撕裂。与手术结果相关分析显示，MR成像在12条肌腱中的表现正确。2例患者的结果为假阳性，1例为假阴性，该例患者因存在其他不相关的异常MR表现仍接受了手术。最常见的MR表现为T1加权和T2加权图像上肌腱实质内信号强度增加（11条肌腱），在斜轴位图像上呈线性或圆形区域（n = 11），在矢状位图像上沿肌腱纵轴呈线性区域（n = 7）。严重病例可见肌腱变形（5条肌腱）。最常见的手术发现是肌腱纵向撕裂（劈裂）（10条肌腱）。
MR成像能够检测出腓骨短肌腱和腓骨长肌腱撕裂。
