目的 探讨多层螺旋CT(MSCT)对 创伤性膈疝(traumatic diaphragmatic hernia，TDH)的诊断价值。方法 回顾性 分析15例经手术证实的TDH的MSCT表现， 其中9例术前行胸腹部MSCT增强扫描检 查。结果 MSCT平扫均清楚显示膈肌破裂 的位置、破裂口大小、膈疝形成及疝内 容物等，CT增强扫描可显示合并的其它 脏器损伤。结论 MSCT对创伤性膈疝的诊 断具有重要价值。

Objective To explore the value of Multi-slice spiral CT(MSCT) in diagnosis of traumatic diaphragmatic hernia(TDH). Methods MSCT features of 15 patients of TDH proved by opertion were analyzed retrospectively.out of which 9 patients underwent Thorax and abdomen MSCT enhanced examinations. Results It showed as diaphragmatic rupture, and the gap position,size and contents herniated into the chest were clear on MSCT plain scan. After the contrast material was injected intravenously, MSCT findings were the other viscera damage of merger. Conclusion Multi-slice spiral CT has significant value in the diagnosis of TDH．
