摘　　要：目的:对肺结核与肺癌空洞患者使用多层螺旋CT进行鉴别诊断的效果做出分析。方法:选取2019年1月~2021年12月在本院确诊的肺结核和肺癌病例共136例作为研究对象,其中,肺结核空洞者77例,肺癌空洞者59例,对两组患者实施多层螺旋CT鉴别诊断,对比分析两组患者的诊断结果,包括空洞情况、空洞特征、病灶临近组织结构特征三方面。结果:肺癌空洞组空洞大小为(40.92±17.07)mm,肺结核空洞组空洞大小为(7.38±8.13)mm,肺癌空洞组空洞大小大于肺结核空洞组,组间差异明显,具有统计学意义(P<0.05)。肺癌空洞组空洞壁厚超过3mm者占比为84.75%,高于肺结核空洞组,组间差异明显,具有统计学意义(P<0.05)。肺癌空洞组空洞位置位于中叶的患者例数占比为18.64%,少于肺结核空洞组,但组间差异没有统计学意义(P>0.05)。肺癌空洞组空洞位置位于上叶的患者例数占比为15.25%,少于肺结核空洞组,组间差异明显,具有统计学意义(P<0.05)。肺癌空洞组空洞部位为下叶的患者例数占比为66.10%,高于肺结核空洞组,组间差异明显,具有统计学意义(P<0.05)。肺癌空洞组空洞CT影像学特征中,内部光滑、外壁毛糙、结节、分叶、短毛刺、偏心性空洞、气液平面患者占比分别为81.36%、77.97%、79.66%、84.75%、84.75%、84.75%、88.14%,均高于肺结核空洞组,组间差异明显,具有统计学意义(P<0.05)。肺癌空洞组CT影像学特征中,钙化者例数占比为49.15%,低于肺结核空洞组,组间差异明显,具有统计学意义(P<0.05)。肺癌空洞组病灶临近组织情况中,周围组织炎症、纵膈淋巴结肿大、纵隔淋巴结钙化、周围卫星灶、胸膜凹陷患者占比分别为13.56%、18.64%、20.34%、20.34%、30.51%,均少于肺结核空洞组,组间差异明显,具有统计学意义(P<0.05)。结论:多层螺旋CT能够较好地对肺部空洞性病变病灶和临近情况进行观察,能够对肺结核、肺癌空洞进行Objective:To study the value of multi-slice spiral CT in differential diagnosis of pulmonary tuberculosis and lung cancer cavity.Methods:136 cases of pulmonary tuberculosis and lung cancer diagnosed in our hospital from January 2019 to December 2021 were selected as the study subjects,including 77 cases of pulmonary tuberculosis cavity and 59 cases of lung cancer cavity.Multislice spiral CT was used to differentiate the two groups of patients,and the diagnosis results of the two groups of patients were compared and analyzed,including cavity situation,cavity characteristics,and adjacent tissue structure characteristics of the focus.Results:The size of cavity in lung cancer cavity group was(40.92±17.07)mm,and that in pulmonary tuberculosis cavity group was(7.38±8.13)mm,the size of cavity in lung cancer cavity group was larger than that in pulmonary tuberculosis cavity group,with significant difference between groups(P<0.05).The proportion of lung cancer cavity group with cavity wall thickness more than 3mm was 84.75%,which was higher than that of pulmonary tuberculosis cavity group,with significant difference between groups(P<0.05).The number of patients with lung cancer cavity located in the middle lobe accounted for 18.64%,which was less than that of pulmonary tuberculosis cavity group,but there was no significant difference between the groups(P>0.05).The number of patients with lung cancer cavity located in the upper lobe accounted for 15.25%,which was less than that of pulmonary tuberculosis cavity group,with significant difference between groups(P<0.05).The number of patients with lower lobe cavity in lung cancer cavity group was 66.10%,higher than that in pulmonary tuberculosis cavity group,with significant difference between groups(P<0.05).In the CT imaging characteristics of cavity in lung cancer cavity group,the patients with smooth interior,rough exterior wall,nodule,lobulation,short bristle,eccentric cavity and gas-liquid plane accounted for 81.36%,77.97%,79.66%,84.75%,84.75%,84.75% and 88.14% respecti
