【摘要】：目的总结老年周围型肺结节的良恶性CT征象。方法所有病例术前均行高分辨率CT(HRCT)检查,统计学分析结节大小、形态、边缘及磨玻璃成分、内部特征在各病理组间差异。结果磨玻璃结节大小及磨玻璃成分在各病理组间差异显著,形态、边缘及内部特征无统计学差异;实性结节大小、边缘特征在各病理组间有统计学差异,形态特征无统计学差异。结论 HRCT在≤10 mm的周围型肺结节的良恶性鉴别上有一定价值,较大结节(8~10 mm)及实性成分的存在(m GGN)或具有分叶特征的实性结节高度提示恶性肿瘤可能。
[Abstract]:Objective to summarize the benign and malignant CT findings of peripheral pulmonary nodules in the elderly. Methods all patients were examined with high resolution CTHRCT before operation, and the size, shape, edge and glass composition of the nodules were analyzed statistically. Results there were significant differences in the size and composition of grinding glass nodules among the pathological groups, but there was no significant difference in morphology, edge and internal features. The marginal features were statistically different among different pathological groups, but there was no significant difference in morphologic features. Conclusion HRCT is valuable in differentiating benign and malignant peripheral pulmonary nodules with 鈮，
