64层螺旋CT在良恶性肺部局灶性磨玻璃结节诊断的应用价值

The value of 64-slice spiral CT in the diagnosis of focal and ground glass nodules in benign and malignant lung

目的探讨多层螺旋CT在肺部良恶性局灶性磨玻璃结节诊断中的应用价值。方法通过分析经临床影像或病理证实34例良恶性的肺部磨玻璃密度结节的CT影像资料。结果 34例磨玻璃结节影中良性12例,恶性22例,良性和恶性病灶的大小、瘤肺界面(清晰光整、模糊),内部密度(p GGO、m GGO)、分叶征、形状(圆形或类圆形)比较差异均有统计学意义(P<0.05),而良恶性病灶毛刺、血管聚集征、空泡征及胸膜凹陷征比较差异无统计学意义(P>0.05)。结论正确识别肺部磨玻璃密度结节CT征象细节和定期随访复查对病变的诊断及鉴别诊断至关重要。

Objective To explore the value of multi-slice spiral CT in the diagnosis of benign and malignant focal ground glass nodules in the lung.Methods CT images of 34 cases of benign and malignant lung ground glass density nodules were confirmed by clinical imaging or pathology.Results Of the 34 cases of ground glass nodules,12 were benign,22 were malignant,There were statistically significant differences between the size of benign and malignant lesions,the tumor lung interface(clear smoothing,blur),internal density(p GGO,m GGO),lobulated sign,shape(P<0.05),but there was no significant difference between the benign and malignant lesions burr,vascular aggregation,vacuole sign and pleural indentation the round and class circle(P>0.05).Conclusion Correct identification of CT signs and lungs in the lungs is essential for the diagnosis and differential diagnosis of lesions.
