64排螺旋CT低剂量胸部扫描在肺癌患者中的诊断价值

Diagnostic value of 64 slice spiral CT low dose chest scan in lung cancer patients

目的探讨64排螺旋CT低剂量胸部扫描在肺癌患者中的诊断价值。方法选择2017年2月~2019年2月在我院收治的100例疑似肺癌患者作为研究对象,所有患者均接受直接数字化X射线摄影系统(DR)胸片检查、64排螺旋CT低剂量胸部扫描检查,对比两种检查方法的检出率、肺部征象检出情况、敏感度、特异度、图像质量优良率。结果 100例患者中,经病理确诊为肺癌的患者96例,非肺癌患者4例。DR胸片检查结果确诊肺癌的患者85例,64排螺旋CT低剂量胸部扫描确诊肺癌的患者95例。64排螺旋CT低剂量胸部扫描检查的灵敏度(98.96%)、准确率(98.00%)高于DR胸片检查(88.54%、86.00%),差异有统计学意义(P<0.05);64排螺旋CT低剂量胸部扫描检查肺门与纵隔淋巴结肿大检出率高于DR胸片检查,差异有统计学意义(P<0.05)。两种方法胸水、空泡征与支气管象征、胸膜凹陷征、厚壁空洞、毛刺征、分叶征检出率比较,差异无统计学意义(P>0.05)。64排螺旋CT低剂量胸部扫描检查图像质量优良率(98.00%)高于DR胸片检查(85.00%),差异有统计学意义(P<0.05)。结论 64排螺旋CT低剂量胸部扫描可显著提高肺癌诊断准确率,且图像质量较高,值得借鉴。

Objective To explore the diagnostic value of 64 slice spiral CT low dose chest scan in lung cancer patients.Methods A total of 100 patients suspected with lung cancer admitted to our hospital from February 2017 to February 2019 were selected as the research objects.All patients were examined by direct digital X-ray radiography system(DR)and 64 row spiral CT low-dose chest scanning.The detection rate,lung sign detection,sensitivity,specificity and image quality of the two methods were compared.Results Of the 100 patients,96 were diagnosed as lung cancer by pathology and 4 were non lung cancer.A total of 85 cases of lung cancer were confirmed by DR chest film.95 cases of lung cancer were diagnosed by low dose chest scan with 64 slice spiral CT.The sensitivity(98.96%)and accuracy(98.00%)of 64 row spiral CT low-dose chest scanning were higher than those of DR chest film examination(88.54%and 86.00%),the differences were statistically significant(P<0.05);the detection rate of hilar and mediastinal lymphadenopathy of 64 row spiral CT low-dose chest scanning was higher than that of DR chest film examination,the difference was statistically significant(P<0.05).There were no significant differences in the detection rates of pleural effusion,vacuole sign and bronchial symbol,pleural indentation sign,thick wall cavity,burr sign and lobulation sign between the two methods(P>0.05).The excellent and good image quality rate of 64 slice spiral CT low-dose chest scan(98.00%)was higher than that of DR chest film(85.00%),the difference was statistically significant(P<0.05).Conclusion Low dose chest scan with 64 slice spiral CT can significantly improve the accuracy of lung cancer diagnosis,and the image quality is high,which is worth learning.
