The correlation of pulmonary ground-glass opacity imaging features and benign,malignant lesions / 实用放射学杂志

ABSTRACT

Objective To analyze the imaging features of ground-glass opacity (GGO) and provide advice for early diagnosis and treatment of malignant lung lesions.Methods The imaging findings of 56 GGOs scanned by MSCT on thin layer scanning were analyzed by χ2 test.Multivariate Logistic regression analysis was performed of the statistically significant variables for univariate analysis.Results Smoothness of the boundary, uniformity of the internal density, and spiculated margin of the GGO lesions were closely related to the diagnosis of malignant lesions.However,size,shape and distribution of the lesions were limited.Conclusion The distribution of GGO(internal, middle and outer band), border, internal density and spiculation are playing important role in early diagnosis of benign and malignant GGO.
