Diagnostic Value of Multi-slice Spiral CT on Differential Diagnosis of Peripheral Lung Cancer and Focal Machine Pneumonia
-
摘要: 目的：探究采用多层螺旋CT对周围型肺癌及局灶性机化性肺炎的鉴别诊断价值。方法：选取我院2014年1月至2018年1月收治的经病理证实的局灶性机化性肺炎患者50例，将其作为对照组，另选取同期收治的60例周围型肺癌患者，将其作为观察组。采用多层螺旋CT进行诊断，比较两组患者临床特征、CT征象及CT强化特征。结果：两组男女比例、基础疾病分布、临床症状比例及实验室检查指标之间的差异无统计学意义（<i<P</i<<0.05）；观察组小病灶患者的年龄显著大于对照组小病灶患者，差异有统计学意义（<i<P</i<<0.05）。对照组与观察组的大病灶患者在空洞及紧贴胸膜影像学征象比例之间差异有统计学意义（<i<P</i<<0.05）。对两组的大小病灶的CT影像学特征在病灶分布、毛刺、血管集束征、支气管充气征、胸膜凹陷及结构疏松之间的差异有统计学意义（<i<P</i<<0.05）。观察组于动脉期CT净增值、总CT净增值均显著低于对照组，差异有统计学意义（<i<P</i<<0.05）。结论：多层螺旋CT扫描可显示局灶性机化性肺炎与周围型肺癌CT影像学征象的差异性和特征性，对无法确诊者应于治疗后实施随访以进一步提高诊断的准确性。Abstract: Objective: To explore the value of multi-slice spiral CT on differential diagnosis of peripheral lung cancer and focal machine pneumonia. Methods: A total of 50 patients with pathologically confirmed focal pneumonia were selected from January 2014 to January 2018 in our hospital. They were selected as the control group, and the other 60 patients with peripheral lung cancer were selected as the observation group. Multislice spiral CT was used to make a diagnosis. The clinical features, CT signs and CT enhancement characteristics of the two groups were compared. Results: The two groups of sex ratio, basic disease distribution, the difference between the clinical symptoms and laboratory indicators of the proportion of no statistical significance (<i<P</i<<0.05); the observation group of small lesions in the age of the patients was significantly higher than that of control group patients, the difference was statistically significant (<i<P</i<<0.05). There was a statistically significant difference between the control group and the observation group of the patients with large lesions in the cavity and the pleura imaging findings (<i<P</i<<0.05). The CT imaging characteristics of the lesions in the control group and the observation group were statistically significant in the lesion distribution, burr, vascular bundle sign, bronchovascular inflation sign, pleural depressions and structural loosening (<i<P</i<<0.05). The net increment of CT and total CT in the observation group were significantly lower than those in the control group, and the difference was statistically significant (<i<P</i<<0.05). Conclusion: Multi-slice spiral CT scan can show the difference and characteristics of CT imaging signs between focal organizing pneumonia and peripheral lung cancer. Follow-up is necessary for those who cannot be diagnosed, so as to further improve the accuracy of diagnosis.
