摘要：

目的 探讨螺旋CT 定性诊断肺磨玻璃结节的临床价值。方法 回顾性分析我院收治的138 例肺磨玻璃结节患者临床资 料，患者均行螺旋CT 扫描检查，并与手术病理比较，其中手术病理证实恶性结节94 例，良性结节44 例，观察螺旋CT 检查结 果与手术病理相符合率情况，分析良、恶性结节病灶大小及影像学特征的差异。结果 肺结节螺旋CT 的符合率为95.7%，误 诊率为4.3%；其中，良性结节符合率为97.7%，肺恶性结节符合率为94.7%。肺恶性结节病灶直径、实性病灶直径均大于良性 结节，差异具有统计学意义（P<0.05）。肺恶性结节的毛刺征、分叶征、胸膜凹陷、边界不清发生率分别为51.1%、33.0%、75.5%、47.9%，均明显高于肺良性结节的13.6%、0.0%、22.7%及20.5%，差异具有统计学意义（P<0.05）。结论 螺旋CT 定性诊 断肺磨玻璃结节价值高，良、恶性结节鉴别作用佳，具有其独特的影像学特征，值得临床应用。

ABSTRACT: Objective To explore the clinical application value of spiral CT in the qualitative diagnosis of pulmonary ground-grass nodule. Methods The clinical data about 138 patients with pulmonary ground-grass nodule in our hospital was retrospectively analyzed. The spiral CT was applied, according to the operation/pathological examinations, there were 94 cases with malignant nodule and 44 cases with benign nodule. The coincidence rate of CT examination results and operation/pathological examination results were observed and the imaging features of benign and malignant nodules were analyzed. Results The coincidence rate of pulmonary nodules was 95.7% and the misdiagnosis rate was 4.3%; of them, the coincidence rate of benign nodules was 97.7%, that of the malignant nodules was 94.7%. The diameter and diameter of solid lesions of the malignant nodules were larger than those of benign nodules, the differences were statistically significant (P<0.05). The speculation, lobular, pleural indentation and unclearly boundary were 51.1%, 33.0%, 75.5%, 47.9% of the malignant nodules respectively, which were significantly higher than 13.6% , 0.0% , 22.7% and 20.5% of the benign pulmonary nodules, the differences were statistically significant (P<0.05). Conclusion Spiral CT has great value in the diagnosis of pulmonary ground -grass nodule, with good identification in benign and malignant nodules, and it is worth clinical application.
