体检人员肺内小结节CT特征与良恶性结果相关性研究

Research on the Correlation Of Small Intrapulmonary Nodules on the CT of Physical Examination People and the Results of Benign and Malignant

目的:探讨研究CT诊断肺内小结节灶良恶性的临床价值,为临床检验选择提供必要参考。方法:选择2013年1月-2015年1月于本院检查存在肺内小结节的90例体检人员作为研究对象,回顾性分析其CT图像,对肺内结节的性质、形态、边缘等进行辨别。结果:本研究患者中共包括良性结节42例,恶性结节48例,恶性结节检出率53.3%。CT形态学特征显示,恶性结节的分叶征、空气支气管征发生率显著高于良性结节,而恶性结节的胸膜凹陷征、钙化征发生率则明显低于良性结节,比较差异均具有统计学意义(P<0.05);恶性结节灶CT形态学特征显示,各癌性病变间的分叶征、胸膜凹陷征发生率比较,差异均有统计学意义(P<0.05);良性结节灶CT形态学特征显示,各病变间的分叶征、毛刺征、胸膜凹陷征、钙化征发生率比较,差异均有统计学意义(P<0.05)。结论:肺内小结节的良恶性鉴别是治疗方案选择的关键,CT检查能够很好的鉴别良恶性结节,具有简便易行、费用低廉的特点,值得在临床上推广和应用。

Objective： To explore and study the clinical value of CT in the diagnosis of benign and malignant lung nodules stove in order to provide necessary reference for the choice of clinical testing.Method： 90 physical examination people who were examined with small intrapulmonary nodules in our hospital from January 2013 to January 2015 were selected as the research objects.Their CT images were retrospectively analyzed.The natures of intrapulmonary nodules such as properties, morphology, edge were analyzed.Result： There were 42 cases of benign nodules and 48 cases of malignant nodules in our research, the detection rate of malignant nodules was 53.3%.The morphology characteristics on CT showed that the incidence rates of lobulation and air bronchogram of the malignant nodules were higher than those of the benign nodules, while the incidence rates of pleural indentation and calcification of the malignant nodules were lower than those of the benign nodules, the differences were all statistically significant （ P〈0.05 ） .The morphology characteristics of the malignant nodules on CT showed that the differences in the incidence rates of lobulation and pleural indentation of different cancer lesions were statistically significant （ P〈0.05 ） .The morphology characteristics of the benign nodules on CT showed that the differences in the incidence rates of lobulation, spiculation, pleural indentation and calcification of different lesions were statistically significant （ P〈0.05 ） .Conclusion： The identification of benign and malignant nodules in the lung is the key to the selection of treatment seheme.CT examination can identify benign and malignant nodules effectively, it has the characteristics of simple and low cost, which is worthy of clinical promotion and application.
