目的分析产气法16层螺旋CT仿真内镜(CTVG)对胃癌的诊断价值。方法选取疑似胃癌患者200例,所有患者均行病理学检查及CTVG检查,以病理学检查结果作为确诊标准,计算CTVG对胃癌诊断的灵敏度和特异性,应用ROC分析CTVG检查的诊断价值。结果 200例患者经病理学检查确诊胃癌135例。而CTVG检查中阳性141例,阴性59例,诊断灵敏度为96.30%、特异度为83.08%。同时经ROC分析显示,CTVG检查对于胃癌诊断有着显著的诊断价值(P<0.05)。结论 CTVG检查对于胃癌有着明确的诊断价值,可将其应用于胃癌的临床诊断中。
Objective To analyze the diagnostic value of gas-generating 16-slice spiral CT virtual endoscopy (CTVG) in gastric cancer. Methods 200 patients with suspected gastric cancer were selected. All patients underwent pathological examination and CTVG examination. The pathological examination was used as the diagnostic criteria to calculate the sensitivity and specificity of CTVG in the diagnosis of gastric cancer. The diagnostic value of CTVG was analyzed by ROC. Results 200 patients were confirmed by pathological examination of 135 cases of gastric cancer. The CTVG positive in 141 cases, negative in 59 cases, the diagnostic sensitivity was 96.30%, the specificity was 83.08%. At the same time by ROC analysis showed that CTVG examination for the diagnosis of gastric cancer has a significant diagnostic value (P <0.05). Conclusion CTVG examination has a clear diagnostic value for gastric cancer, which can be used in the clinical diagnosis of gastric cancer.
