【摘要】 目的 探讨螺旋CT多平面重建(MPR)在创伤性膈疝诊断中的价值。 方法 回顾性分析18例经手术证实的创伤性膈疝的螺旋CTMPR征象。 结果 本组18例创伤性膈疝术前均得以明确诊断，其螺旋CT MPR征象主要表现为:(1)所有病例均显示患侧膈肌影模糊或消失。(2)胸腔内异常密度团块影(腹内脏器疝入)17例(其中左侧14例:结肠5例，脾脏3例，大网膜2例，胃2例，肝左叶合并小肠、结肠1例，左肾上极1例;右侧3例:肝脏2例，肝脏合并结肠肝曲1例)。(3)邻近肺组织受压膨张不全13例。(4)并发伤12例(肋骨骨折5例，胸腔积液3例，肺挫伤1例，脾挫伤1例，肝挫伤2例，其中继发肝脓肿1例)。 结论 螺旋CT是创伤性膈疝诊断中最可靠的检查方法之一，MPR应得以常规运用。

    【Abstract】 Objective To explore the diagnostic value of multiplanar reconstruction(MPR)of spiral CT for trau-matic diaphragmatic hernia.Methods The multiplanar reconstruction of spiral CT findings of18cases with traumatic diaphragmatic hernia thatwere proved by surgical operation were reviewed retrospectively.Results The MPR of spiral CT diagnosis was correct in all cases.Traumatic diaphragmatic hernia had the following appearance:(1)diaphragma's image faded or disappear in18cases.(2)Abnormal density missions in the pleural cavity ......
