多层螺旋CT对薄壁囊腔型肺癌诊断的影像学征象特点分析

Analysis of Imaging Features of Thin-Walled Cystic Lung Cancer Diagnosed by Multi-Slice Spiral CT

目的:分析多层螺旋CT诊断薄壁囊腔型肺癌的诊断价值和影像学特点。方法:纳入2020年3月~2022年10月到本院进行治疗的152例肺癌患者为研究对象,所有患者入院后均经过多层螺旋CT进行诊断,并以病理诊断结果为金标准,分析多层螺旋CT诊断薄壁囊腔型肺癌的价值和影像学特征。结果:(1)经病理诊断确诊薄壁囊腔型肺癌19例,而多层螺旋CT检出薄壁囊腔型肺癌16例,CT诊断和病理诊断结果差异不显著(P>0.05);(2)经多层螺旋CT诊断薄壁囊腔型肺癌的阳性预测值为93.75%、阴性预测值为97.06%、敏感度为78.95%、特异度为99.25%、准确度为96.71%、约登指数为78.2%、误诊率为0.75%、漏诊率为21.05%;(3)多层螺旋CT诊断薄壁囊腔型肺癌具有特征性的影像学图像表现。结论:薄壁囊腔型肺癌属于一种特殊类型的肺癌,近年来发病率有升高的趋势。经多层螺旋CT对薄壁囊腔型肺癌进行诊断与病理诊断结果没有明显的差异,可作为对患者临床诊断的主要参考依据,能为临床的诊断和治疗工作提供参考。

Objective:To investigate the diagnostic value and imaging characteristics of multi-slice spiral CT in the diagnosis of thin-walled cystic lung cancer.Methods:The subjects of this study were 152 patients with lung cancer who received treatment in our hospital from March 2020 to October 2022.All patients were diagnosed with multi-slice spiral CT after admission,and the value and imaging features of multi-slice spiral CT in the diagnosis of thin-walled cystic lung cancer were analyzed with pathological diagnosis results as the gold standard.Results:①19 cases of thin-walled cystic lung cancer were confirmed by pathological diagnosis,while 16 cases of thin-walled cystic lung cancer were detected by multi-slice spiral CT.The difference between CT diagnosis and pathological diagnosis was not significant(P>0.05);②The positive predictive value,negative predictive value,sensitivity,specificity,accuracy,Jordan index,misdiagnosis rate,and missed diagnosis rate of thin-walled cystic lung cancer diagnosed by multi-slice spiral CT were 93.75%,97.06%,78.95%,99.25%,96.71%,78.2%,and 21.05%,respectively;③The diagnosis of thin-walled cystic lung cancer with multi-slice spiral CT has characteristic imaging findings.Conclusion:Thin-walled cystic lung cancer is a special type of lung cancer and its incidence has been increasing in recent years.There is no significant difference between the diagnosis results of thin-walled cystic lung cancer by multi-slice spiral CT and pathological diagnosis,which can be used as the main reference for clinical diagnosis of patients and provide reference for clinical diagnosis and treatment.
