摘 要: | 目的研究多层螺旋CT(MSCT)增强扫描对肺癌的诊断及鉴别价值。方法以我院2012年2月-2015年2月就诊的100例肺部占位患者为研究对象,均行MSCT平扫及增强扫描,观察比较不同肺部占位病变MSCT平扫CT值、增强峰值及强化增值,同时与病理学结果对照,分析MSCT增强扫描对肺癌诊断灵敏度、特异度及准确度。结果与病理学结果对照,MSCT平扫敏感度、特异度、准确度分别为69.0%、66.7%、68.0%,均显著低于增强扫描的91.4%、88.1%、90.0%,比较差异有统计学意义(P0.05)。肺癌、炎性假瘤、肺结核球三组增强峰值、强化增值比较差异均有统计学意义(P0.01)。鳞癌、腺癌、小细胞癌CT净增强值比较差异显著(P0.01)。结论 MSCT增强扫描对肺癌诊断准确度、灵敏度、特异度均较高,且通过观察MSCT增强扫描影像特征可帮助与其他占位病变鉴别,以提高肺癌诊断准确率。

Abstract: | Objective To study the value of multi-slice spiral CT (MSCT) enhanced scan in the diagnosis and differential diagnosis of lung cancer.Methods 100 cases of patients with pulmonary space occupying lesions treated in our hospital from February 2012 to February 2015 were treated as the research objects. MSCT plain scan and enhanced scan were performed in all patients. The CT values of MSCT, enhancement peak value and enhancement appreciation of different pulmonary space occupying lesions were compared and were compared with the pathological results at the same time. The sensitivity, specificity and accuracy of MSCT enhanced scan in the diagnosis of lung cancer were analyzed.Results Compared with pathological results, the sensitivity, specificity and accuracy of MSCT plain scan (69.0%, 66.7% and 68.0%) were significantly lower than those of enhanced scan (91.4%, 88.1%, 90%) (P<0.05). There were statistically significant differences in enhancement peak value and enhancement appreciation of lung cancer, inflammatory pseudotumor and pulmonary tuberculoma of three groups (P < 0.01). The differences in CT net enhancement value between squamous cell carcinoma, adenocarcinoma and small cell carcinoma were significant (P<0.01).Conclusion MSCT enhanced scan has higher accuracy, sensitivity and specificity for diagnosis of lung cancer and through observing the imaging findings of MSCT enhanced scan, it can help to differentiate lung cancer from other space occupying lesions to improve the diagnostic accuracy of lung cancer. |
