【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。
[Abstract]:Objective to investigate the imaging features of multi-slice spiral CT screening in high-risk patients with lung cancer. Methods A total of 107 subjects who were screened as high-risk population for lung cancer at the time of physical examination were screened by multi-slice spiral CT, and the results were examined pathologically in patients with suspected lung cancer, and the results were recorded in detail. The diagnostic coincidence rate of multi-slice spiral CT in screening diagnosis of lung cancer was analyzed. To summarize the imaging features of multi-slice spiral CT in lung cancer patients and non-lung cancer patients. Results among the 1107 patients with high risk of lung cancer, 78 cases were diagnosed as suspected lung cancer by multi-slice spiral CT. 60 suspected cancer nodules and 20 suspected tumor masses were found, with a total of 80. Among 78 patients with suspected lung cancer screened by multi-slice spiral CT, 64 cases were diagnosed as lung cancer by pathological examination. The coincidence rate of multi-slice spiral CT in screening diagnosis of lung cancer was 82.1% (64 / 78). There were 55 cancer nodules (83. 3%) and 11 cancer masses (16. 7%), with a total of 66. (2) nodules were found in 53 cases (82.8%). 55 nodules were detected, the average size of nodules was 1.8 cm, of which 33 (60.0%) had obvious CT signs, and 22 (40.0%) had no CT signs. Lung lesions were found in 11 cases (17.2%). The average size of nodules was 3.5 cm. Among them, 7 (63.6%) had obvious CT signs, and the remaining 4 (36.4%) had no CT signs. Conclusion the proportion of cancer nodules in patients with lung cancer is higher than that in cancer masses, and the characteristics of multi-slice spiral CT images are more obvious.
