64层螺旋CT同像素冠状位重建对非创伤性急腹症诊断价值

目的探讨64层螺旋cT同像素冠状位重建对非创伤性急腹症诊断价值。方法随机选取我院2014年5月至2016年5月收治的有急性腹痛接受64层螺旋cT检查的患者300例，应用西门子SOMATON Sensation64层螺旋CT对患者进行平扫和增强扫描，应用冠状面重建进行后期处理，然后对冠状位、横断位及其二者结合的图像对患者诊断的阳性情况、敏感性、特异性、准确性、阴性预测值、阳性预测值及冠状位重建的辅助价值进行统计分析。结果冠状位、横断位及其二者结合的图像对患者诊断的阳性率之间的差异均不显著（P〉0.05）；冠状位结合横断位的图像对患者诊断的敏感性、特异性、准确性、阴性预测值均显著高于冠状位、横断位（P〈0.05），而冠状位的图像对患者诊断的准确性、阳性预测值又均显著高于横断位（P〈0．05），但冠状位、横断位的图像对患者诊断的敏感性、特异性、阴性预测值之间的差异均不显著（P〉0．05），冠状位、冠状位结合横断位的图像对患者诊断的阳性预测值之间的差异也不显著（P〉0．05）；冠状位重建对有急腹症和无急腹症患者的识别率、诊断正确率、排除率之间的差异均不显著（P〉0．05）。结论64层螺旋CT同像素冠状位重建对非创伤性急腹症具有较高的诊断价值。

Objective to investigate the 64 layer spiral CT with pixel coronary a reconstruction of the diagnostic value of traumatic acute abdominal disease. Methods randomly selected from May 2014 to May 2014 treated with acute abdominal pain to accept 64 layers spiral CT examination of 300 cases of patients, the application of Siemens SOMATON since 64 layers spiral CT plain scan and enhanced scan was performed at applied coronal reconstruction for later processing, then the coronary, cross sectional and its combination of images for diagnosis of patients with positive situation, the sensitivity, specificity, accuracy, negative predictive value, positive predictive value of coronary reconstruction auxiliary value were analyzed. Results coronary, cross sectional and its combination of images for diagnosis of patients with positive differences were not significant （P〉0.05） ; Coronary position combined with cross sectional images of patients diagnosed sensitivity, specificity, accuracy, and negative predictive value were significantly higher than that of coronary tran section （P〈0.05）, and coronary images of patients diagnosed accuracy, positive predictive value and were significantly higher than transection （P〈0.05）, but the coronary, cross sectional images of patients diagnosed sensitivity, specificity, and negative predictive value differences were not significant （P〉0.05）, coronary position and coronary position combined with cross sectional images of the patient＇s diagnosis is also the difference between the positive predictive value was not significant （P〉0.05） ; Coronary reconstruction with acute abdominal pain and the recognition rate and the diagnostic accuracy of patients with acute abdomen, elimination rate differences were not significant （P〉0.05）. Conclusion layer spiral CT with pixel coronary 64 reconstruction of traumatic acute abdomen has high diagnostic value.
