摘　　要：目的:评价多层螺旋CT对肺内孤立性结节良恶性的鉴别诊断价值,观察良性及恶性结节的CT征象。方法:选择本单位于2020年7月~2021年7月收治的50例肺内孤立性结节患者,根据病理结果,将33例肺部良性病变患者设为对照组,将17例肺癌患者设为研究组。全部给予多层螺旋CT检查,计算诊断符合率,并组间对比结节平均直径以及胸膜牵拉征、血管包被征、毛刺征、分叶征等CT征象的分布率。结果:研究组的诊断符合率为94.12%(16/17),对照组的诊断符合率为96.97%(32/33)。研究组的结节平均直径为(3.41±1.36)cm,大于对照组的(1.14±0.69)cm,统计学对比有差异(t=6.445,P=0.000)。研究组有9例(52.94%)患者存在分叶征,13例(76.47%)患者存在毛刺征,10例(58.82%)患者存在血管包被征、14例(82.35%)患者存在胸膜牵拉征;对照组有3例(9.09%)患者存在分叶征,4例(12.12%)患者存在毛刺征,6例(18.18%)患者存在血管包被征、3例(9.09%)患者存在胸膜牵拉征,两组比较,统计学对比有差异(χ^(2)=11.828,20.704,8.517,26.837,P=0.001,0.000,0.004,0.000)。结论:多层螺旋CT征象对肺内良恶性孤立性结节均有较高鉴别诊断价值,临床应积极推行,以实现对肺癌的早期发现和治疗。Objective:To evaluate the value of multi-slice spiral CT in the differential diagnosis of benign and malignant solitary pulmonary nodules,and to observe the CT signs of benign and malignant nodules.Methods:50 patients with solitary pulmonary nodules admitted to our unit between July 2020 and July 2021 were selected.According to the pathological results,33 patients with benign lung lesions were selected as the control group,and 17 patients with lung cancer were selected as the research group.All were examined by multi-slice spiral CT,the diagnosis coincidence rate was calculated,and the average diameter of nodules and the distribution rate of CT signs such as pleural traction sign,vascular enveloping sign,burr sign,and lobular sign were compared between groups.Results:The diagnosis coincidence rate of the research group was 94.12%(16/17),and the diagnosis coincidence rate of the control group was 96.97%(32/33).The average diameter of nodules in the research group was(3.41±1.36)cm,which was larger than(1.14±0.69)cm in the control group.There was a statistical difference(t=6.445,P=0.000).In the research group,9 case(52.94%)had lobular sign,13 cases(76.47%)had burr sign,10 cases(58.82%)had vascular envelopment sign,and 14 cases(82.35%)had pleural traction.In the control group,3 cases(9.09%)had lobular sign,4 cases(12.12%)had burr sign,6 cases(18.18%)had vascular envelopment sign,and 3 cases(9.09%)had pleura traction sign,pairwise comparison,statistically different(χ^(2)=11.828,20.704,8.517,26.837,P=0.001,0.000,0.004,0.000).Conclusion:Multi-slice spiral CT signs have a high differential diagnosis value for benign and malignant solitary nodules in the lung,and should be actively implemented in clinical practice to realize the early detection and treatment of lung cancer.
