基于螺旋CT影像的肺部毛玻璃结节的诊断价值

Study on the Diagnosis Value of Pulmonary Ground Glass Opacity Nodules Based on Multislice Spiral CT

目的探讨基于螺旋CT影像的肺部毛玻璃结节(pulmonary ground glass opacity nodule,GGO)的诊断价值。方法采用回顾性研究方法,选择肺部毛玻璃结节患者58例作为研究对象,根据良恶性分为2组。观察2组的病灶界面、病灶边缘、病灶的形态、病灶大小及GGO的邻近结构。结果 2组中病灶大小、病灶边缘、病灶形态、病灶界面例数对比,差异有统计学意义(P<0.05);良性病变组的胸膜凹陷者0例,胸膜增厚者27例;恶性病变组的胸膜凹陷者16例,胸膜增厚者15例,2组对比有统计学意义(P<0.05)。结论多层螺旋螺旋CT可作为肺部毛玻璃结节良恶性的诊断方法。

Objective To evaluate the diagnostic value of pulmonary ground glass opacity nodules（GGO） based on spi- ral CT images. Methods 58 patients with pulmonary ground glass opacity nodules were selected as retrospective study. They were divided into 2 groups according to benign and malignant. The lesions interface, edge of lesions and lesions form, and the size of the lesions, proximity structure of the 2 groups were observed. Results There were significant differences in lesions interface, edge of lesions,lesions form, and the size of the lesions, proximity structure between the 2 groups （ P 〈 0.05 ）. The pleural indentation of benign lesion was 0,the pleural thickening was 27 cases;the pleural indentation of malignant lesions was 16 cases, the pleural thickening was 15 cases, which had significant differences between the 2 groups （ P 〈 0.05 ）. Condusion Multislice spiral CT images can be used as a diagnosis method for pulmonary ground glass opacity nodules of benign and malignant.
