双源CT低剂量扫描显示磨玻璃结节对早期肺癌诊断的价值分析

Value of Low-dose Dual Source CT Scan Showing Ground Glass Nodules in the Diagnosis of Early Lung Cancer

目的:探析双源CT低剂量扫描显示磨玻璃结节征象对早期肺癌诊断的价值。方法:在某院2016年10月～2018年6月收治的胸部体检筛查出肺磨玻璃结节患者中选出300例为对象,均进行双源CT低剂量扫描检出磨玻璃结节,根据病理结果分为良性组和恶性组,对比两组患者的CT征象。结果:良性组患者的pGGN概率低于恶性组,P<0.05;两组患者的CT征象对比,其中毛刺征概率对比差异不明显,P>0.05;结节形状、结节直径、结节边缘、分叶征、空泡征、支气管征和血管集束征的对比,两组之间差异有统计学意义,P<0.05。结论:双源CT低剂量扫描显示磨玻璃结节在早期肺癌诊断中具有重要价值,观察结节的CT征象特点,判断结节的良恶性,为临床治疗提供借鉴。

Objective: To analyze the value of low-dose dual source CT scan showing ground glass nodules in the diagnosis of early lung cancer. Methods: 300 patients with pulmonary ground glass nodules screened by chest physical examination from October 2016 to June 2018 in a hospital were selected as subjects, all of whom were detected by dual source CT low-dose scanning. According to the pathological results,they were divided into benign group and malignant group,and the CT signs of the two groups were compared. Results: The probability of pGGN in benign group was lower than that in malignant group,P<0.05.The contrast of CT signs between the two groups was not significant,P>0.05. Compared nodule shape,nodule diameter,nodule edge,lobulation sign,vacuole sign, bronchial sign and vascular bundle sign: the difference between the two groups was statistically significant,P<0.05. Conclusion: Dual source CT low-dose scan shows that ground glass nodules are of great value in the diagnosis of early lung cancer, it can observe the CT features of nodules, determine the benign and malignant of nodules, and provide reference for clinical treatment.
