目的 探究电子计算机断层扫描 (CT)对腹部闭合性损伤定性、定位诊断的 应用价值。方法 回顾性分析我院行手术 治疗的98例腹部闭合性损伤患者临床资 料，比较CT、超声检查与金标准(手术)定 性及定位检出情况差异，评估CT、超声的 诊断效能。结果 98例腹部闭合性损伤患 者共出现108处实质性脏器损伤，24处为 空腔脏器损伤；CT对腹部闭合性损伤的定 性诊断准确率明显高于超声(P＜0.05)， 且对腹部实质性脏器及空腔脏器损伤的定 位诊断准确率均高于超声(P＜0.05)。结 论 CT在腹部闭合性损伤定性、定位诊断 中具有较高的准确率，对临床治疗有指导 意义。 【关键

Objective To explore the application value of computed tomography (CT) in qualitative diagnosis and localization diagnosis of closed abdominal trauma. Methods The clinical data of 98 patients with closed abdominal trauma who underwent surgical treatment in our hospital were analyzed retrospectively. The differences of qualitative and localization detection conditions between CT, ultrasound and gold standard (surgery) were analyzed and compared, and the diagnostic value of the two methods was assessed. Results There were 108 parenchyma organ injuries and 24 hollow organ injuries among 98 cases of patients with closed abdominal trauma. The accuracy of qualitative diagnosis of closed abdominal trauma by CT was significantly higher than that by ultrasound (P<0.05), and the accuracies of localization diagnosis of abdominal parenchyma organ injuries and hollow organ injuries were higher than those by ultrasound (P<0.05). Conclusion CT has a high accuracy rate in the qualitative diagnosis and localization diagnosis of closed abdominal trauma, and it is beneficial for guiding clinical treatment.
