目的:探讨高分辨率CT在肺孤立性结节诊断中的应用价值。方法:采用CT设备为德国产西门子螺旋CT机,对58例肺内孤立结节扫描及静脉注药高分辨CT扫描。结果:高分辨率CT与常规CT征象比较,两者空洞及钙化显示率无显著性差异,其它如胸膜凹陷征、血管集束征、毛刺、支气管充气征等肺癌征象高分辨率CT的显示率明显升高。结论:常规CT扫描结合高分辨CT扫描或增强扫描,能明确显示结节征象、内部结构等,有助于鉴别良、恶性孤立性肺结节。
Objective: To explore the value of high resolution CT in the diagnosis of solitary pulmonary nodules. Methods: The CT equipment was made in Germany by Siemens Spiral CT, 58 cases of isolated pulmonary nodules and intravenous high-resolution CT scan. Results: There was no significant difference between high resolution CT and conventional CT findings in terms of cavitation and calcification. Other pleural signs such as pleural indentation, vascular bundling, burr, and bronchial airway sign were significantly higher in high resolution CT Rise. Conclusion: Conventional CT scan combined with high-resolution CT scan or enhanced scan can clearly show nodules signs, internal structure, etc., is helpful to identify benign and malignant solitary pulmonary nodules.
