摘要
目的探讨肺癌高危患者经多层螺旋CT筛查诊断的影像特点。方法选取体检时被筛选为肺癌高危人群的107例受试者为研究对象,均予以多层螺旋CT筛查,对筛查结果显示为疑似肺癌者给予病理检查,详细记录检查结果,分析多层螺旋CT在肺癌筛查诊断中的诊断符合率;归纳整理肺癌确诊患者及非肺癌患者多层螺旋CT的影像特点。结果 1107例肺癌高危患者中,经多层螺旋CT筛查为疑似肺癌者共78例,发现可疑癌结节60个,可疑癌肿块20个,共计80个;经多层螺旋CT筛查为疑似肺癌的78例患者中,经病理检查确诊为肺癌者64例,多层螺旋CT在肺癌筛查诊断中的诊断符合率为82.1%(64/78);其中癌结节55个(83.3%),癌肿块11个(16.7%),共计66个;2肺部癌灶为结节者53例(82.8%),检出癌结节55个,平均结节大小为1.8cm,其中33个(60.0%)合并明显CT征象,剩余22个(40.0%)未合并CT征象;肺部病灶为肿块者11例(17.2%),检出癌肿块11个,平均结节大小3.5cm,其中7个(63.6%)合并明显CT征象,剩余4个(36.4%)未合并CT征象。结论肺癌确诊患者中癌结节所占比例较癌肿块高,多层螺旋CT影像特征性较为明显。
Objective To investigate the imaging characteristics of high-risk patients with lung cancer screened and diagnosed by multi-slice spiral CT. Methods 107 subjects screened as high- risk group of lung cancer when receiving physical examination were selected as the research objects and were screened by multi-slice spiral CT. Patients whose screening results showed suspected lung cancer were given pathological examination and the results were recorded in detail. The accordance rate of multi-slice spiral CT in the screening and diagnosis of lung cancer was analyzed; The imaging characteristics of multi-slice spiral CT of patients with and without lung cancer were summarized and reorganized. Results 1Among the 107 high-risk patients with lung cancer, 78 cases were with suspected lung cancer screened by multi-slice spiral CT. 60 suspected cancer nodules and 20 suspected masses were found, a total of 80. Among the 78 patients with suspected lung cancer screened by multi-slice spiral CT, 64 patients were confirmed with lung cancer by pathological examination. The coincidence rate of multi-slice spiral CT in screening and diagnosis of lung cancer was 82.1%（64/78）, including 55（83.3%） cancer nodules, 11（16.7%） cancer masses, a total of 66. 2There were 53 cases（82.8%） of lung neoplastci foci as nodules and 55 cancer nodules detected. The average size of the nodules was 1.8cm, including 33（60.0%） complicated with obvious CT signs and the remaining 22（40.0%） not. The pulmonary lesions were masses in 11 cases（17.2%） and 11 cancer masses were detected. The average size of nodules was 3.5cm, including 7（63.6%） complicated with obvious CT signs and the remaining 4（36.4%） not. Conclusion The proportion of cancerous nodes is higher than that of tumor masses in patients diagnosed with lung cancer. The imaging findings of multi-slice spiral CT are obvious.
