肺结核空洞与肺癌空洞的CT影像差异分析

Differential analysis of CT image on diagnosis of pulmonary cavities of tuberculosis and lung cancer

目的分析肺结核空洞患者与肺癌空洞患者的CT影像差异。方法选取43例肺结核空洞患者的临床资料(对照组)和43例肺癌空洞患者的临床资料(观察组)。两组患者均行计算机体层摄影(CT)检查,比较两组患者的影像学表现(分叶征、毛刺征、胸膜凹陷征、壁结节、钙化及空洞壁的厚薄)。结果观察组患者的钙化和厚壁空洞的发生率均低于对照组,而分叶征、胸膜凹陷征、壁结节、毛刺征和薄壁空洞的发生率均高于对照组,差异均有统计学意义(P﹤0.05)。结论肺结核空洞患者与肺癌空洞患者的CT影像表现存在一定的差异。临床实施CT检查和分析,可以对两种疾病进行鉴别和诊断。

Objective To compare and analysis the differences between pulmonary cavities of tuberculosis and lung cancer on CT images. Method Data of 43 cavitary pulmonary tuberculosis patients （control group） and 43 caritary lung cancer patients （observation group） were collected. CT imaging was performed in two groups of patients. The imaging manifestations of the two groups, including lobulation sign, spicule sign, pleural indentation sign, mural nodule, calcifica- tion, thickness of the cavity wall, were observed and compared. Result Compared with the control group, the incidence rates of calcification and thick-walled cavity were lower in observation group, and the incidence rates of lobulated sign, pleural indentation sign, mural nodule spicule sign and thin-walled cavity were higher in observation group （P〈0.05）. Conclusion There are some differences in the CT imaging manifestations between pulmonary cavities of tuberculosis and lung cancer. In clinical practice, CT can be used to identify and diagnose the two kinds of diseases.
