作者分析了22例结节状BAC在CT上的磨玻璃密度影,并复习了这些病例的术后表现,以确定BAC磨玻璃密度影的预后价值。男性15例,女性7例,35～73岁。共有24个经病理证实的结节状BAC(2例病人在同一肺叶有2个结节)。CT上肿瘤大小(最大直径)1～4cm(平均2.6cm)。诊断BAC的标准为:没有其它原发性腺癌的证据;光学显微镜显示肿瘤细胞沿完整的肺泡壁生长(伏壁生长),使用SomatomDR CT机,8mm层厚连续扫描,20例病人补充了2或4mm薄层扫描,深吸气
The authors analyzed the glass densities of 22 nodular BACs on CT, and reviewed the postoperative performance of these cases to determine the prognostic value of BGC ground density. There were 15 males and 7 females, 35-73 years old. There were 24 pathologically confirmed nodular BACs (2 patients had 2 nodules in the same lobe). CT tumor size (maximum diameter) 1 to 4 cm (average 2.6 cm). The criteria for diagnosis of BAC were: no evidence of other primary adenocarcinomas; light microscopy showed tumor cells growing along the intact alveolar wall (vessel wall growth), continuous scans of 8 mm layer thickness using a Somatom DR CT machine, 20 patients supplemented with 2 or 4mm thin layer scanning, deep inhalation
