摘要
目的对比分析胸部X线平片与低剂量螺旋CT在肺结节中诊断中的应用效果。方法将2015年8月至2018年8月我院收治的经手术、病理检查进行确诊为肺部结节性病变的患者86例,所有患者均进行胸部X线平片与低剂量螺旋CT扫描检查,根据扫描方法不同分成对照组(X线平片)和观察组(低剂量螺旋CT),对所有患者的影像学资料进行收集,比较两种检查方法对肺结节的检出数量以及形态特征。结果两组患者均检出结节数93枚,观察组对钙化、空洞、毛刺征、分叶征、支气管征、胸膜黏连征形态学检出数多于对照组,且数据差异均具有统计学意义(P<0.05)。86例患者中,对照组扫描测量肺结节直径约为(6.42±5.47)mm,观察组扫描测量肺结节直径约为(13.19±7.86)mm,两组患者测量结节直径比较,数据差异具有统计学意义(t=6.556,P=0.000)。结论低剂量螺旋CT在对肺结节的诊断中,对肺结节检出数量以及形态特征表现方面较胸部X线平片更具优势,且最大程度的减少了患者受照剂量,具有临床推广应用价值。
Objective To compare and analyze the application of chest X-ray plain film and low-dose spiral CT in the diagnosis of pulmonary nodules. Methods 86 patients with pulmonary nodular lesions from August 2015 to August 2018 were diagnosed by surgery and pathology. All patients underwent chest X-ray plain film and low-dose spiral CT scanning. According to different scanning methods, the patients were divided into control group(X-ray plain film) and observation group(low dose spiral CT). The imaging data of all patients were collected. The number and morphological characteristics of pulmonary nodules detected by the two methods were compared. Results 93 nodules were detected in both groups. Morphological detection of calcification, cavitation, burr sign, lobulation sign, bronchial sign and pleural adhesion sign in the observation group was more than that in the control group, and the difference was statistically significant(P<0.05). Among 86 patients, the diameter of pulmonary nodules measured in control group was about(6.42±5.47) mm, while that in observation group was about(13.19±7.86) mm. There was significant difference in the diameter of pulmonary nodules measured between the two groups(t=6.556, P=0.000). Conclusion In the diagnosis of pulmonary nodules, low-dose spiral CT is superior to chest X-ray plain film in detecting the number and morphological features of pulmonary nodules, and reduces the radiation dose of patients to the greatest extent. It has clinical application value.
