MSCT增强扫描对肺癌的诊断及鉴别价值

Value of MSCT Enhanced Scan in Diagnosis and Differential Diagnosis of Lung Cancer

目的:探讨多层螺旋CT(MSCT)增强扫描对肺癌的诊断及鉴别价值。方法:将某院收治的105例肺部占位患者作为研究对象,均进行MSCT平扫及增强扫描,比较两种方式CT值、强化增值、准确度、特异度、敏感度。结果:肺结核球、炎性假瘤、肺癌3组间MSCT平扫CT值比较无显著差异(P>0.05),3组间强化增值比较有显著差异(P<0.05),鳞癌CT净增强值显著高于小细胞癌、腺癌(P<0.05),MSCT增强扫描准确度(90.47%)、特异度(91.80%)、敏感度(88.63%)显著高于MSCT平扫(69.52%、70.49%、68.18%)(P<0.05)。结论:MSCT增强扫描相较于MSCT平扫而言,具有较高的准确度、特异度以及敏感度,可有效鉴别不同肺部占位病变,值得在临床上推广使用。

Objective：To investigate the value of multi slice spiral CT （MSCT） enhanced scan in the diag nosis and differential diagnosis of lung cancer. Methods：A total of 105 patients with lung involvement in a hospital were enrolled in this study. All patients underwent MSCT scan and enhanced scan. Compared CT value, enhancement value added, accuracy, specificity and sensitivity of two groups. Results： The pulmonary tuberculoma ,inflammatory pseudotumor and lung cancer of three groups with MSCT plain CT value had no significant difference （P〉0.05）, the value of strengthening the comparison between the three groups had significant difference （P〈0.05）. The net enhancement value of squamous cell carcinoma on CTwas signifi cantly higher than that of small cell carcinoma and adenocarcinoma （P〈0.05）. The accuracy of MSCT en hanced scan （90.47%）, specificity （91.80%） and sensitivity （88.63%） were significantly higher than those of MSCT scan （69.52%, 70.49%, 68. 18%） （P〈0.05）. Conclusion： Compared with MSCT scan, MSCT enhanced scan has higher accuracy, specificity and sensitivity, and can effectively identify different lung le sions, h is worth popularizing in clinical practice.
