MSCT对2 cm以下的周围型肺癌及炎性结节的临床诊断价值分析

Clinical diagnostic value of MSCT on peripheral lung cancer and inflammatory nodules < 2cm

目的研究多层螺旋CT(MSCT)对2cm以下的周围型肺癌及炎性结节的临床诊断价值。方法选取2014年12月至2016年12月经病理以及临床检查确诊为2cm以下的周围型肺癌患者86例与炎性结节患者32例。对比不同CT征象表现及CT增强表现。结果 7mm重建征象中肺癌组小泡征、毛刺征、胸膜凹陷征、分叶征、小棘突征、血管集束征占比显著高于炎性结节组(P<0.05)。1mm HRCT重建征象中肺癌组的上述征象占比均显著高于炎性结节组(P<0.05)。肺癌组CT增强表现为均匀强化,人数占比显著高于炎性结节组,而强化幅度>20Hu人数占比显著更低(P<0.05)。结论 MSCT对2cm以下的周围型肺癌及炎性结节的临床诊断价值较高,可作为临床上鉴别周围型肺癌及炎性结节的首选检查方案。

Objective To study the clinical diagnostic value of MSCT on peripheral lung cancer and inflammatory nodules 2 cm. Methods From December 2014 to December 2016,the pathological and clinical examination diagnosis of less than 2 cm of 86 cases of peripheral lung cancer patients and 32 patients with inflammatory nodules were enrolled. Their CT and enhanced CT features were analyzed. Results For 7 mm reconstruction signs,the rate of vesiclesign,burr sign,pleural introcession,sublobe,small spines and blood vessels was higher in the lung cancer group than in the inflammatory nodules group（ P〈0. 05）. For 1 MMHRCT reconstruction signs,the rate of those above signs was significantly higher in the lung cancer group than in the inflammatory nodules group（ P〈0. 05）. Uniform reinforcement cases of CT enhanced performance were significantly higher in the lung cancer group than in the inflammatory nodule group,and especially lower for amplitude number 20 Hu（ P〈0. 05）. Conclusion MSCT has a high clinical diagnostic value on less than 2 cm of peripheral lung cancer inflammatory nodules,which can be used as a clinical identification of peripheral lung cancer and the first choice for inflammatory nodules.
