摘　　要：目的探究CT平扫与三期增强扫描在对肺结节的诊断中的应用价值。方法采用回顾性分析的方法对我院2016年6月-2017年5月收治的56例患者进行研究分析,56例患者入院后两周内都行CT平扫和三期增强扫描,并经手术、病理检查进行确诊为肺部结节性病变。结果 51例患者中良性结节组26例和恶性结节组30例;CT平扫良、恶性肺结节平均CT值比较,差异无统计学意义(P>0.05);CT增强扫描60s良、恶性肺结节的平均CT值比较,差异存统计学意义(P<0.05),增强扫描15s、30s所测的CT值比较均无统计学意义(P>0.05)。以最大CT净增值20~60HU为恶性结节,测得CT三期增强扫描对恶性结节诊断的敏感性为92.86%、特异性为86.73%、诊断准确性为81.46%。结论 CT平扫与三期增强扫描在肺结节中具有较高的诊断准确性,且对良性和恶性具有一定的鉴别诊断价值。Objective To investigate diagnostic value of CT plain scan and Tri-phase Enhancement scan in pulmonary nodules. Methods Used to analyze 56 patients our hospital from 2016 May-2017 June were selected to study by A retrospective analysis. Patients were treated with CT plain and three enhanced scan for two weeks after admission, and were diagnosed as pulmonary nodular lesions by surgical and pathological examination. Results There were 26 cases of benign nodules patients and malignant nodules patients in 51 cases. Comparing the average CT value by CT plain, there was no difference between benign nodules and malignant nodules（P〈0.05）, and compared with benign nodules, the average CT value of malignant pulmonary nodules by CT enhanced scan 60 s benign was alleviated significantly（P〈0.05）. There was no statistically significant difference between the CT values of enhanced scan 15 s and 30 s（P〈0.05）. The CT added value between 20-60 HU was treated as malignant nodules. The sensitivity of the CT three phase enhanced scan to the diagnosis of malignant nodules was 92.86%, the specificity was 86.73%, and the diagnostic accuracy was 81.46% by measuring maximum net value of CT between 20-60 HU of malignant nodule. Conclusion CT plain scan and three phase enhanced scan have high diagnostic accuracy in pulmonary nodules, and have certain differential diagnosis value for benign and malignant.
