摘　　要：目的 研究西门子双源CT双能量扫描对肺癌鉴别诊断及预后评估的价值。方法 回顾性分析2016年1月至2019年1月于我院接受肺癌鉴别诊断者105例。所有患者均使用西门子双源CT采用双能量模式对肺部行双期增强扫描;将105例患者根据病变程度分为良性病变组59例和恶性病变组46例;其中恶性病变组患者根据肺癌病理类型分为腺癌组28例和鳞癌组18例;根据肺癌分化程度分为低分化腺癌组13例,中分化腺癌组组15例,低分化鳞癌组8例和中分化鳞癌组10例;根据预后分为死亡组35例和存活组70例;分别比较各组患者CT平均值(HU)、容积CT剂量指数(HU)、容积CT增强值。结果 良性病变组CT平均值、容积CT剂量指数、容积CT增强值均显著低于恶性病变组(P<0.05);腺癌组CT平均值、容积CT剂量指数、容积CT增强值均显著高于鳞癌组(P<0.05);低分化腺癌组CT平均值、容积CT剂量指数、容积CT增强值均显著高于中分化腺癌组(P<0.05);低分化鳞癌组CT平均值、容积CT剂量指数、容积CT增强值均显著高于中分化鳞癌组(P<9.05);存活组CT平均值、容积CT剂量指数、容积CT增强值均显著低于死亡组(P<0.05)。结论 西门子双源CT双能量扫描可以有效区分良性和恶性、不同病理类型、不同分化程度的肺癌,且对预后评估有着较高的价值。Objective To study the value of dual-energy scan with Siemens dual-source CT(DSCT) in the differential diagnosis of lung cancer and prognosis evaluation.Methods A retrospective analysis was performed on the 105 patients who underwent differential diagnosis of lung cancer in the hospital from January2016 to January 2019.All patients underwent dual-energy scan with Siemens DSCT.According to different lesion degree,they were divided into benign lesion group(59 cases) and malignant lesion group(46 cases).According to different pathological types of lung cancer,they were divided into adenocarcinoma group(28 cases) and squamous cell carcinoma(SCC) group(18 cases).According to different differentiation degree,they were divided into in poorly differentiated adenocarcinoma group(13 cases),moderately differentiated adenocarcinoma group(15 cases),poorly differentiated SCC group(8 cases) and moderately differentiated SCC group(10 cases).According to different prognosis,they were divided into death group(35 cases) and survival group(70 cases).CT mean value(HU),CT dose index volume(HU),and volume CT enhancement were compared among all groups.Results CT mean value,CT dose index volume and volume CT enhancement in benign lesion group were significantly lower than those in malignant lesion group(P<0.05).CT mean value,CT dose index volume and volume CT enhancement in adenocarcinoma group were significantly higher than those in SCC group(P<0.05).CT mean value,CT dose index volume and volume CT enhancement in poorly differentiated adenoca rcinoma group were significa ntly higher than those in moderately differentiated adenocarcinoma group(P<0.05).CT mean value,CT dose index volume and volume CT enhancement in poorly differentiated SCC group were significantly higher than those in moderately differentiated SCC group(P<0.05).CT mean value,CT dose index volume and volume CT enhancement in survival group were significantly lower than those in death group(P<0.05).Conclusion The dual-energy scan with Siemens DSCT can effectively distingui
