探讨CT在肺内孤立性结节良、恶性定性诊断中的价值 材料与方法:回顾分析经病理证实的73例肺内孤立性结节的CT表现 结果:肺内良、恶性结节病变好发部位无明显差异 CT征象提示,分叶征、小毛刺征、小泡征、胸膜凹陷征、阻塞性肺炎、纵隔淋巴结肿大、胸腔积液仅见于肺癌;病变周围有卫星病灶仅见于肺结核,血结节内钙化、空洞也多见于肺结核;脑膜增厚多见于炎性结节 结论:综合分析CT影像征象,可提高对肺内孤立性结节诊断的准确率。
To investigate the value of CT in the diagnosis of benign and malignant solitary pulmonary nodules.Materials and Methods: CT findings of 73 cases of solitary pulmonary nodules confirmed by pathology were retrospectively analyzed.Results: The benign and malignant nodules in the lungs were well developed No significant difference in the location of CT signs suggest that the lobulation sign, small burr levy, vesicular levy, pleural indentation, obstructive pneumonia, mediastinal lymph nodes, pleural effusion only seen in lung cancer; lesions around the satellite lesions found only in tuberculosis, blood Nodular calcification, cavity is also more common in tuberculosis; Meningeal thickening more common in inflammatory nodules Conclusion: Comprehensive analysis of CT imaging signs, can improve the accuracy of the diagnosis of solitary pulmonary nodules.
