摘要
目的:探讨无口服对比剂急诊CT平扫对闭合性腹部创伤诊断价值。方法:回顾性分析349例闭合性腹部创伤患者,采用多层螺旋CT无口服对比剂急诊腹盆腔CT平扫的结果,与经临床随访和外科剖腹探查证实的诊断结果进行对比,观察其符合率。结果:CT报告292例阴性,57例阳性,其中7例假阴性和5例假阳性,对闭合性腹部创伤诊断敏感性为91%,特异性为98%,阳性预测值为88%,阴性预测值为98%。结论:无口服对比剂急诊CT平扫可以作为闭合性腹部创伤患者首选影像学检查方法。
Objective To investigate the value of emergency unenhanced CT without oral contrast material in the diagnosis of blunt abdominal trauma. Methods Three hundred and forty-nine patients with blunt abdominal trauma underwent abdominopelvic emergency unenhanced CT without oral contrast material using a muhislice spiral CT scanner initially and whose clinical outcome was confirmed by clinical follow-up and surgery. Results On initial CT reports, there were 292 negative cases and 57 positive cases. Compared with clinical outcomes, there were 7 false negative and 5 false positive with the sensitivity of 91% ,the specificity of 98% ,the positive predictive value of 88%, and the negative predictive value of 98%. Conclusion Emergency unenhanced CT without oral contrast material can be an efficient and first line radiological examination in the diagnosis of blunt abdominal trauma.
