摘要
目的探讨低剂量螺旋CT与胸部X线筛查肺癌高危人群的临床应用价值研究。方法随机抽取2018年1月至12月于我院进行体检的90例肺癌高危人群作为研究对象,均行低剂量螺旋CT和胸部X线检查,以手术病理和穿刺病理为金标准,比较不同检查方法对肺癌的检出诊断率,并总结肺癌的相关影像学特征。结果低剂量螺旋CT检查对肺癌高危人群肺部结节的检出率和对肺癌的检出率均显著高于胸部X线检查,比较差异间具有统计学意义(P<0.05)。在X线检查中肺癌可见肺门旁肿块,伴有分叶征和空洞。CT检出20例肺部结节者中14例为肺癌,其中5例中央型肺癌于CT平扫中均可见肺门位置出现球形或椭圆形结节状肿块,累及到肺内,同时能够观察到斑片状阴影,9例周围型肺癌于CT中可见病灶位于左上叶3例,右下叶2例和右上叶3例,均可表现为分叶状肿块及空洞,其中5例出现小结节影,可见短细毛刺;2例表现为结节状、小点状、小片状空洞,同时出现钙化影(不规则),肺小叶之间的间隔增大,呈毛玻璃样渗出征象。结论与胸部X线相比较而言,低剂量螺旋CT检查对于肺癌高危人群肺部结节和肺癌的检出率更高,可更清晰的显示肺部病灶内部情况和小结节,更有利于肺癌的早期检出诊断。
Objective To explore the clinical application value of low-dose spiral CT and chest X-ray in screening high-risk groups of lung cancer.Methods A total of 90 patients with high risk of lung cancer who underwent physical examination in our hospital from January 2018 to December 2018 were randomly selected as subjects.All patients underwent low-dose spiral CT and chest X-ray examination.All patients underwent low-dose spiral CT and chest X-ray examination.The detection rates and diagnosis rates of lung cancer by different methods were compared with surgical pathology and puncture pathology,and the relevant imaging features of lung cancer were summarized.Results The detection rates of low-dose spiral CT examination for pulmonary nodule and for lung cancer were significantly higher than those of chest X-ray examination.The difference was statistically significant(P<0.05).In the X-ray examination,lung cancer showed involved intrapulmonary mass in thehilum of the lung,and moderate to low density shadows,accompanied by lobulated signs and halo signs.14 of the 20 patients with pulmonary nodules were detected as lung cancer by CT,and 5 of them were central lung cancer.In their CT scan,a spherical or elliptical nodular mass was seen in the hilar position,involving the lungs.At the same time,patchy shadows can be observed.In 9 cases of peripheral lung cancer,the lesions were located in the left upper lobe in 3 cases,the right lower lobe in 2 cases and the right upper lobe in 3 cases,all of which showed lobulated masses and cavities,of which 5 cases showed nodular shadows,which were short and fine burrs,of which 2 cases showed nodular,small-point,cavities like small strip,and shadow of calcification at the same time,and their interval between the pulmonary lobule was enlarged,showing exudation signs like ground glass.Conclusion Compared with chest X-ray,low-dose spiral CT examination has higher detection rate of pulmonary nodules and lung cancer in high-risk group of lung cancer,which can clearly show the internal conditions of lung lesions and smaller nodules,and is more conducive to the early detection of lung cancer.
