作者对经外科手术切除的,肿块最大径在15mm以下的微小周围型肺癌的CT影像与病理所见作了对比研究。共74例,男36例,女38例,年龄26～83岁。病理组织学为腺癌61例,鳞癌2例,大细胞癌1例,小细胞癌1例,小细胞癌与腺鳞癌混合型1例,类癌8例。在注射对比剂后作全肺常规CT扫描,用螺旋扫描法在病变部作高分辨CT扫描,屏气,床速2mm/s。照相条件统一为肺野窗位-600HU,窗宽1600HU,纵隔窗位40HU,窗宽400HU。常规CT层厚10mm,间距10mm,高分辨
The authors compared surgically resected CT images of small, peripheral lung cancers with a maximum diameter of 15 mm or less with pathology. A total of 74 cases, 36 males and 38 females, aged 26 to 83 years. Histopathology of adenocarcinoma in 61 cases, squamous cell carcinoma in 2 cases, large cell carcinoma in 1 case, small cell carcinoma in 1 case, small cell carcinoma and adenosquamous carcinoma in 1 case, carcinoid tumor in 8 cases. After injection of contrast agent for the whole lung routine CT scan with spiral scan in the lesion for high-resolution CT scan, breath holding, bed speed 2mm / s. Unification of the lung photography conditions for the window-600HU, window width 1600HU, longitudinal window 40HU, window width 400HU. Conventional CT layer thickness 10mm, spacing 10mm, high resolution
