摘要
目的:探讨IQon光谱计算机断层扫描(CT)在肺部结节良恶性鉴别诊断中的应用价值.方法:选择2021年1月至2023年2月福建中医药大学附属第二人民医院收治的81例肺部结节患者,均进行IQon光谱CT检查,以病理活检结果为标准,计算IQon光谱CT在肺部结节良恶性鉴别诊断中的诊断价值,并比较肺部结节良恶性患者的光谱CT参数.结果:以病理活检为标准,81例肺部结节患者中,58例(71.60%)为恶性,23例(28.40%)为良性.IQon光谱CT诊断肺部结节结果与病理活检的一致性κ值为 0.941,以病理活检为标准,IQon光谱CT诊断肺部结节的灵敏度为96.55%、特异度为100.00%、准确度为97.53%、阳性预测值为100.00%、阴性预测值为92.00%.恶性肺部结节患者光谱CT参数中的静脉期原子序数(Zeff)、标准化原子序数(nZeff)高于良性肺部结节患者,差异具有统计学意义(P＜0.05).结论:IQon光谱CT在肺部结节良恶性鉴别诊断中表现出较高的诊断效能.
Abstract
Objective To investigate the application value of IQon spectral computed tomography(CT)in the differential diagnosis of benign and malignant pulmonary nodules.Methods A total of 81 patients with pulmonary nodules admitted to the Second Affiliated People's Hospital of Fujian University of Traditional Chinese Medicine from January 2021 to February 2023 were selected to undergo IQon spectral CT examination.Based on the results of pathological biopsy,the diagnostic value of IQon spectral CT in the differential diagnosis of benign and malignant pulmonary nodules was calculated,and the spectral CT parameters of benign and malignant pulmonary nodules were compared.Results According to pathological biopsy,58(71.60%)of 81 patients with pulmonary nodules were malignant and 23(28.40%)were benign.The κ value of IQon spectral CT diagnosis of pulmonary nodules and pathological biopsy is 0.941,using pathological biopsy as the standard.The sensitivity,specificity,accuracy,positive predictive value and negative predictive value of IQon spectral CT in the diagnosis of pulmonary nodule were 96.55%,100.00%,97.53%,100.00%and 92.00%respectively.The venous atomic number(Zeff)and standardized atomic number(nZeff)of spectral CT parameters in patients with malignant pulmonary nodules were higher than those in patients with benign pulmonary nodules,and the difference was statistically significant(P＜0.05).Conclusion IQon spectral CT showed high diagnostic efficiency in the differential diagnosis of benign and malignant pulmonary nodules.
