摘　　要：目的:探讨多层螺旋CT高分辨率扫描及三维重建在肺内直径小于1.0cm小结节病变中的诊断价值,以提高肺内小结节检出率和定性诊断的准确率。方法:回顾性分析40例经病理和随访证实的直径1.0cm以下肺内小结节病变患者的临床资料和多层螺旋CT高分辨率扫描影像表现以及三维重建影像资料。结果:40例小结节病例中共发现小结节43枚,实性结节23例,毛玻璃结节17例。炎性结节8例,陈旧性结核灶15例,早期肺癌17例,毛玻璃结节中早期肺癌占11例。结论:肺内直径小于1.0cm小结节因其体积小,临床症状不典型,导致定性诊断困难,但通过多层螺旋CT高分辨率扫描以及三维后处理综合分析其影像学表现,可以做出比较明确的影像学诊断。Objective To investigate the diagnostic value of multi-slice spiral CT high-resolution scanning and three- dimensional reconstruction in the diagnosis of pulmonary nodules with small diameter of less than 1.0cm. Methods The clinical data of 40 patients with pulmonary nodules with diameter below 1.0cm were analyzed retrospectively, and the clinical features of multi-slice spiral CT scan and three-dimensional reconstruction were retrospectively analyzed. Results In 40 cases of small nodules, small nodules were found in 43 cases, solid nodules in 23 cases, and glass nodules in 17 cases. There were 8 cases of inflammatory nodules, old tuberculosis foci in 15 cases, early stage of lung cancer in 17 cases, and early stage lung cancer in the glass wool nodules in 11 cases. Conclusion Pulmonary nodules with diameter less than 1.0cm because of its small volume, clinical symptoms are not typical, resulting in qualitative diagnosis is difficult, but through high resolution multi-slice spiral CT scanning and 3D postprocessing comprehensive analysis of imaging findings, can make clear imaging diagnosis.
