CT三维重建技术在孤立性肺结节诊断及对危险因素分析的应用效果探讨

The Application Effect of CT Three-dimensional Reconstruction Technology in the Diagnosis of Solitary Pulmonary Nodule and Analysis of Risk Factors

目的:比较CT三维重建技术与普通放射诊断孤立性肺结节的差异性并对危险因素进行分析。方法:本研究回顾性分析我院进行诊治的孤立性肺结节患者80例,根据检查方法将患者分为了两组,观察组(CT三维重建技术组)和对照组(普通放射线组),分析两组的诊断资料,初步分析影响诊断准确性的危险因素。结果:对照组检出恶性小结节例数25例,敏感性为62.5%,观察组检出恶性小结节例数36例,敏感性为90%,两组诊断敏感性比较具有统计学意义;对照组实性结节例数21例,经随访后更正例数38例,准确性为55.26%,观察组实性结节例数33例,经随访后更正例数39例,准确性为84.62%,两组准确性比较具有统计学意义;经分析:结节最大径、磨玻璃成分影响孤立性肺结节诊断的独立危险因素。结论:CT三维重建技术在孤立性肺结节的定性鉴别方面有诊断优势,影响诊断的独立危险因素应引起相关临床科室重视。

Objective:To compare the difference between CT three-dimensional reconstruction technology and ordinary radiological diagnosis of solitary pulmonary nodules and to conduct risk factors. analysis.Methods:This study retrospectively divided 80 patients with solitary pulmonary nodules diagnosed and treated in our hospital. According to the inspection methods, the patients were divided into two observation groups(CT three-dimensional reconstruction technology group) and control groups(general radiation group). Group’s diagnostic data, preliminary analysis of risk factors that affect the accuracy of diagnosis.Results:25 cases of malignant nodules were detected in the control group, with a sensitivity of 62.5%, and 36 cases of malignant nodules were detected in the observation group, with a sensitivity of 90%. The diagnostic sensitivity of the two groups was statistically significant.;The number of solid nodules in the control group was 21 cases, 38 cases were corrected after follow-up, the accuracy was 55.26%, the number of solid nodules in the observation group was 33 cases, and 39 cases were corrected after follow-up, the accuracy was 84.62%, the accuracy of the two groups is statistically significant;after analysis: the maximum diameter of the nodule and ground glass composition are independent risk factors that affect the diagnosis of solitary pulmonary nodule.Conclusion:CT three-dimensional reconstruction technology has diagnostic advantages in the qualitative identification of solitary pulmonary nodules. The independent risk factors affecting the diagnosis should be paid attention to by relevant clinical departments.
