摘要目的 对比急诊胸腹部创伤患者予以DR及螺旋CT诊断的临床结果,并分析图像特征.方法 将2016年4月至2017年3月收治的47例急诊胸腹部创伤患者作为研究对象,均接受DR及螺旋CT的影像学检查,回顾性分析其临床资料,对比两种方式的诊断结果.结果 手术确诊显示共有15例肋骨骨折,13例为肺挫伤,肝脏损伤及肾脏损伤分别为11例、8例;螺旋CT与DR摄片对于肋骨骨折的诊断结果对比,差异无统计学意义(P＞0.05).螺旋CT对于肺挫伤、肝脏损伤、肾脏损伤的诊断准确率及总诊断率依次为92.31％、90.91％、100.00％、95.74％,均显著高于DR摄片的53.85％、45.45％、50.00％、63.83％,差异有统计学意义(P＜0.05);左肾挫伤并包膜下血肿CT片中能看出明显的错侧损伤,且均有明显的血肿,所有CT片均可清晰看到病灶位置.结论 相比DR摄片,在对急诊胸腹部创伤患者予以临床诊断时,螺旋CT的诊断准确率相对更高,影像片可清晰显示病灶,值得推广.

abstractsObjective To compare the clinical results of DR and spiral CT in the diagnosis of emergent thoracic and abdominal trauma and to analyze the image characteristics.Methods 47 patients with emergent thoracic and abdominal trauma treated at our hospital from April,2016 to March,2017 were selected as study objects.All the patients were examined by DR and CT.Their clinical data were retrospectively analyzed.The diagnostic results were compared between the two methods.Results The surgical results confirmed that 15 cases got rib fracture,13 pulmonary contusion,11 liver injury,and 8 kidney injury.There was no statistical difference between spiral CT and DR in the diagnosis of rib fracture (P ＞ 0.05).The diagnostic accuracy of spiral CT for lung contusion,liver injury and kidney damage(92.31％,90.91％,and 100.00％) and total diagnostic rate (95.74％)were significantly higher than those of DR (53.85％,45.45％,50.00％,and 63.83％),with statistical difference (all P ＜ 0.05).The left renal contusion and subcapsular hematoma showed obvious wrong side injuries in CT and there were obvious hematomas.The location of the lesion could be clearly seen by all CT images.Conclusions The diagnostic accuracy of spiral CT is higher than that of DR in the clinical diagnosis of patients with emergent thoracic and abdominal trauma.The image of the lesion can be clearly displayed.Therefore,it is worth being generalized.
