肺磨玻璃结节影像诊断思维及对策

Imaging diagnosis reasoning and countermeasures of pulmonary ground-glass nodules

肺磨玻璃结节是目前一个常见临床现象,且多数为肿瘤。新分类将这些肿瘤性病变划分为侵袭前病变和侵袭性腺癌,并单独提出微侵癌,因为其手术切除治愈率几乎百分百。CT是首选术前检查手段,尤其生理通气辅助的超高分辨率靶扫描可以更好显示磨玻璃结节的特征,在此基础上可以高效确定磨玻璃结节的侵袭性,值得推荐应用。

The pulmonary ground glass nodule(GGN)is a common clinical phenomenon at present,and most of them are tumors.The new classification classifies these neoplastic lesions into pre invasive lesions and invasive adenocarcinoma,and proposes micro invasive carcinoma separately,because the cure rate of surgical resection is almost 100%.Computed tomography(CT)is the first choice for preoperative examination,especially the ultra-high resolution target scanning assisted by physiological ventilation can better display the characteristics of GGN.On this basis,it can effectively determine the aggressiveness of GGN,which is worth recommended.
