摘要
目的分析多层螺旋CT对肺部结节影像学诊断的临床应用价值。方法83例行CT检查的肺部结节患者,所有患者均行胸部CT平扫及强化扫描。记录多层螺旋CT引导下经胸肺活检的结节位置,以组织病理诊断结果为金标准,统计多层螺旋CT对肺部结节的检出率、结节良恶性及类型,并分析多层螺旋CT检查肺部结节良恶性的诊断准确率、敏感性和特异性。结果83例肺部结节患者在多层螺旋CT引导下经胸肺活检的结节位置:发生右上叶、右中叶、右下叶各28、7、15例,左上叶、左下叶各21和12例。上叶肺结节检出率最高,为59.04%(49/83),其次是下叶、右中叶,下叶肺结节检出率为32.53%(27/83),右中叶肺结节检出率为8.43%(7/83)。穿刺部位以俯卧位为主43例,其次是仰卧位28例,侧卧位12例。组织病理诊断显示33例良性结节,50例恶性结节;多层螺旋CT检查肺部结节28例良性,55例恶性。以组织病理诊断结果为金标准,肺部结节多层螺旋CT检查对肺部结节的检出率为100.00%(83/83)。其中炎症假瘤12例,肺结核4例,肺内淋巴结3例,支气管腺瘤4例,肺错构瘤5例,小细胞肺癌2例,各类肺腺癌及癌前病变53例。肺部结节多层螺旋CT检查肺部结节良恶性诊断准确率、敏感性和特异性分别为93.98%(78/83)、100.00%(50/50)、84.85%(28/33)。结论不同病理类型的肺部结节在多层螺旋CT成像上表现有差异,多层螺旋CT影像学特征有助于肺部结节的临床诊断。
Objective To analyze the clinical value of multilayer spiral CT on the imaging of pulmonary nodules.Methods 83 patients with pulmonary nodules requiring CT examination were selected,and all underwent chest CT plain scan and enhanced scan.The location of nodules in multilayer spiral CT-guided transthoracic lung biopsies was recorded,and the detection rate,nodule benignity and malignancy and their types of multilayer spiral CT were counted using histopathological diagnostic results as the gold standard,and the diagnostic accuracy,sensitivity and specificity of benign and malignant pulmonary nodules examined by multi-slice spiral CT were analyzed.Results Nodule location in 83 patients with pulmonary nodules on multilayer spiral CT-guided transthoracic lung biopsy showed that there were 28 cases in the right upper lobe,7 cases in the right middle lobe,and 15 cases in the right lower lobe;there were 21 cases in the left upper lobe and 12 cases in the left lower lobe.The highest detection rate of pulmonary nodules was 59.04%(49/83)in the upper lobe,followed by 32.53%(27/83)in the lower lobe and 8.43%(7/83)in the right middle lobe.The puncture site was predominantly in the prone position in 43 cases,followed by 28 cases in the supine position and 12 cases in the lateral position.Histopathological diagnosis showed 33 benign nodules and 50 malignant nodules,while multilayer spiral CT showed 28 benign and 55 malignant pulmonary nodules.With histopathological diagnosis as the gold standard,the detection rate of pulmonary nodules by multilayer spiral CT of pulmonary nodules was 100.00%(83/83).Among them,there were 12 cases of inflammatory pseudotumor,4 cases of pulmonary tuberculosis,3 cases of intrapulmonary lymph nodes,4 cases of bronchial adenoma,5 cases of lung hamartoma,2 cases of small cell lung cancer,and 53 cases of various types of lung adenocarcinoma and precancerous lesions.The accuracy,sensitivity and specificity of benign and malignant pulmonary nodules detected by multi-slice spiral CT were 93.98%(78/83),100.00
