目的:研究肺部混合磨玻璃结节影(mixed ground-glass opacity,mGGO)的疾病构成、诊断技术及疾病与影像学特点关系。方法前瞻性研究经病理证实的19例连续性肺部mGGO病例的基本临床资料、影像学特征(包括病灶大小、边缘特征、GGO百分比、内部特征、邻近特征、结节外表现)。根据确诊结果分为良性病变组和恶性病变组,并比较上述观察指标。结果19例肺部mGGO结节中良性病变4例(良性病变组),恶性15例(恶性病变组)。恶性病变组中CT表现分叶征(86.7%)、边界清楚(86.7%)和血管集束征(80.0%)明显高于良性病变组。恶性病变组GGO百分比≤50%为14例,良性病变组仅1例(P=0.016)。基本临床资料、病灶大小、部位、内部特征、结节外表现及结节至壁层胸膜距离在良恶性病变组中均无差异(P均>0.05)。11例CT引导经皮穿刺肺活检均获确诊。结论肺部mGGO结节的CT表现对病变性质鉴别诊断有一定意义。经皮穿刺肺活检术对肺部mGGO结节确诊率高。
目的:研究肺部混閤磨玻璃結節影(mixed ground-glass opacity,mGGO)的疾病構成、診斷技術及疾病與影像學特點關繫。方法前瞻性研究經病理證實的19例連續性肺部mGGO病例的基本臨床資料、影像學特徵(包括病竈大小、邊緣特徵、GGO百分比、內部特徵、鄰近特徵、結節外錶現)。根據確診結果分為良性病變組和噁性病變組,併比較上述觀察指標。結果19例肺部mGGO結節中良性病變4例(良性病變組),噁性15例(噁性病變組)。噁性病變組中CT錶現分葉徵(86.7%)、邊界清楚(86.7%)和血管集束徵(80.0%)明顯高于良性病變組。噁性病變組GGO百分比≤50%為14例,良性病變組僅1例(P=0.016)。基本臨床資料、病竈大小、部位、內部特徵、結節外錶現及結節至壁層胸膜距離在良噁性病變組中均無差異(P均>0.05)。11例CT引導經皮穿刺肺活檢均穫確診。結論肺部mGGO結節的CT錶現對病變性質鑒彆診斷有一定意義。經皮穿刺肺活檢術對肺部mGGO結節確診率高。

Objective To investigate the proportion and diagnostic techniques of pulmonary mixed ground -glass opacity(mGGO), and the relationship between the disease and computed tomography (CT) characteristics. Methods Single mGGO were found in 22 consecutive patients which underwent multi-detector CT.Nineteen ( 86.4%) consecutive cases of mGGO nodules that were histologically confirmed were included in this prospective tri -al.All cases of pulmonary mGGO nodules were divided into two groups:malignant nodules group and benign nodules group.The clinical and radiological characteristics ( including the lesions′size, edge characteristics , internal charac-teristics, etc) of all patients were recorded .These parameters were statistically compared between the two groups .Re-sults There were 4 benign and 15 malignant mGGOs .No statistical differences were found between benign and ma-lignant mGGOs in terms of demographic data , lesions′size, internal characteristics and external manifestations .The frequency of lobulation ( 86.7%) , well-defined interface ( 86.7%) and vascular convergence ( 80.0%) was signifi-cantly higher in malignant mGGOs than that in benign mGGOs .The percentage of GGO component ≤50%was high-er in malignant mGGOs.The diagnostic of 11 cases were confirmed through percutaneous core needle lung biopsy un-der multi-CT fluoroscopic guidance .Conclusion The CT characteristics of pulmonary mGGO nodules have certain significance in the differential diagnosis of lesions properties of pulmonary mGGO nodules .CT fluoroscopy-guided needle aspiration biopsy is a useful diagnostic technique for mGGO nodules .
