毛刺征应用CT诊断小肺癌周围型的价值

Value of Spicule Sign in CT in Diagnosis of Small Peripheral Lung Cancer

目的对小肺癌周围型患者进行影像学检查,分析毛刺征对患者肺癌诊断的应用价值。方法方便选择2016年1月—2017年1月该院收治的57例小肺癌周围型患者,作为实验组,另选取同样例数良性孤立性肺结节患者作为对照组,对两组患者均采用CT诊断方法进行诊断,比较两组影像学检查结果差异,着重分析毛刺征的差异,观察不同病情下患者毛刺征的影像学表现,为小肺癌周围型诊断带来帮助。结果实验组出现毛刺的几率更大,占54.39%,对照组毛刺现象少,占29.83%,腺癌患者的毛刺征发病率65.00%,鳞癌毛刺征发病率38.46%,肺泡癌毛刺征发病率27.27%,毛刺征情况、不同影像学处理方法下,患者毛刺征的发现情况差异有统计学意义(P<0.05)。结论小肺癌周围型患者的影像学检查特征明显,尤其在毛刺征的影像学表现与良性孤立性肺结节差异明显,能够作为小肺癌周围型的诊断依据。

Objective To conduct the imaging examination of patients with small peripheral lung cancer and analyze the application value of spicule sign in diagnosis of lung cancer. Methods Convenient selection 57 cases of patients with small peripheral lung cancer admitted and treated in our hospital from January 2016 to January 2017 were selected as the experimental group, and 57 cases of patients with benign solitary pulmonary nodules were selected as the control group, and both groups adopted the CT diagnosis method and the difference in the imaging examination result was compared and the difference in the spicule sign was especially analyzed and the imaging manifestations of spicule sign under different disease conditions were observed thus providing help for the diagnosis of small peripheral lung cancer. Results The occurrence probability of spicule signs in the experimental group was higher, accounting for 54.39% and 29.83% in the control group, and the incidence rate of spicule signs of adenocarcinoma patients and of squamous carcinoma patients and alveolar cell carcinoma patients was respectively 65.00% and 38.46% and 27.27%, and the difference was statistically significant（P〈0.05）.Conclusion The imaging examination features of patients with small peripheral lung cancer is obvious, especially the difference between the imaging manifestations of spicule signs and benign solitary pulmonary nodules is obvious, which can be used as the diagnosis basis for the small peripheral lung cancer.
