手肌腱损伤DECT成像分析

Dual energy CT imaging analysis of tendon injury in hand

目的初步探讨双能CT(DECT)在显示手肌腱韧带损伤中的临床应用价值。方法对20例手部外伤患者行手DECT扫描,观察肌腱及周围组织情况。所有病例诊断均经手术或结合临床及其他影像学资料证实。结果 DECT对肌腱整体外形、迂曲、粘连、受压及断裂显示较好,但对肌腱内部及周围腱鞘、滑膜改变显示不如MRI。结论 DECT能显示大多数手肌腱正常解剖结构及异常病变,对临床诊断手肌腱损伤或病变具有一定价值。

Objective To discuss the clinical application value of dual energy CT（DECT） in diagnosis of the tendon injury in hand.Methods Twenty patients with hand injuries received the DECT scanning,and the situations of tendon and surrounding tissues were observed.The diagnosis for all cases was identified by operation or clinical manifestations and other imaging data.Results DECT displayed very well the complete shape of tendons and the situations of circuity,adherence,and rupture.But MRI was more sensitive than DECT in displaying the situations within the tendons and changes in the surrounding tendinous sheath and synovial membrane.Conclusion DECT can display most anatomic structure and abnormal lesions of hand tendon and has certain value in the clinical diagnosis of injury and lesion in hand tendon.
