目的:分析螺旋CT定性诊断肺磨玻璃结节的临床价值及准确性.方法:在本院诊疗的肺磨玻璃结节患者中随机选取72例为探究对象,病理选取日期为2019年6月-2021年6月,全部患者诊疗资料均完整保存且满足研究要求.72例患者均通过手术病理证实为肺磨玻璃结节,其中良性结节有31个,恶性结节有41个,全部患者均实施螺旋CT检查,以手术病理结果统计诊断情况,分析螺旋CT定性诊断的临床价值与准确性.结果:螺旋CT诊断符合率低于手术病理诊断,组间差异并无统计学意义,P > 0.05;恶性结节对于分叶征、毛刺征、血管增粗、“,”Objective: To analyze the clinical value and accuracy of spiral CT in the qualitative diagnosis of pulmonary ground glass nodules. Methods: A total of 72 patients with pulmonary ground glass nodules diagnosed and treated in our hospital were randomly selected as the research objects. The pathological selection date was from June 2019 to June 2021. All patients\'\' diagnosis and treatment data were completely preserved and met the research requirements. All 72 patients were confirmed to be pulmonary ground glass nodules by surgery and pathology, including 31 benign nodules and 41 malignant nodules. Spiral CT examination was performed in all patients. Clinical value and accuracy of diagnosis. Results: The coincidence rate of spiral CT diagnosis was lower than that of surgical and pathological diagnosis, and there was no significant difference between groups, P>0.05; The detection rate of the sign, uniform internal structure, and vascular cluster sign was significantly higher than that of benign nodules, and the detection rate of round or quasi-round, clear edge was lower than that of benign nodules, P<0.05; The diameter of solid components was significantly lower than that of malignant nodules, and the difference was statistically significant, P<0.05. Conclusion: Spiral CT diagnosis has important clinical value in the diagnosis of pulmonary ground glass nodules. It can obtain accurate, clear and comprehensive imaging manifestations, which can improve the diagnostic accuracy and provide more objective imaging for disease diagnosis and treatment. It is of great significance for the diagnosis and treatment of diseases and improving the prognosis, and can be promoted in clinical practice.
