急性跟腱撕裂的影像学诊断

目的探讨跟腱撕裂的X线平片和MRI诊断价值。方法分析21例有急性踝关节损伤病史、经手术证实为跟腱完全撕裂或部分撕裂患者的X线平片和MRI表现，并与手术结果对照。结果21例MRI均有异常表现，诊断跟腱完全撕裂7例，部分撕裂14例，MRI表现为跟腱增粗，腱内信号增高，腱束连续性完全中断或部分中断。X线片5例诊断跟腱撕裂，12例疑似撕裂，4例正常。手术结果完全撕裂9例，部分撕裂12例。结论MRI能准确显示跟腱撕裂的程度和部位，对临床治疗具有重要的指导意义；X线可作为跟腱撕裂初诊的辅助检查，但明确诊断还有赖于MRI。

Imaging diagnosis of the acute Achilles tendon rupture

Objective To evaluate the diagnostic value of Achilles tendon rupture by using X-ray plain films and MR images. Methods The plain films and MRI findings in 21 patients with operation proved acute Achilles tendon rupture were analyzed, and every manifestation on MR and operation were compared. Results The Achilles tendon rupture was diagnosed on MRI in all 21 cases. Complete rupture of Achilles tendon was showed in 7 and partial rupture in 14. MRI appearance of the rupture represented as thickening of Achilles tendon, hyperintensity in the tendon, and completely or partly discontinuance of the fibrous bundle. X-ray showed Achilles tendon rupture in 5, suspicious rupture in 12, and normal in 4. Operation showed Achilles tendon complete rupture in 9 and partial rupture in 12. Conclusion MRI can accurately show the degree and location of acute Achilles tendon rupture, which is very helpful for treatment. X-ray is the adminicular method in detecting Achilles tendon rupture and the diagnosis should be depended on MRI to confirm the the acute Achilles tendon rupture.
