F/52 体Marom EM 等( 2000):对于直径8-10mm的病灶,18F-FDG
PET对其进行良恶性鉴别诊断的敏感度、特异度和准确率 分别为96%、88%和94%
➢ Tsunezuka等(2007):18F-FDG PET对直径≦2cm的腺癌,A 型的假阴性率为100%,B型为80%,C型为47%,D-F的阳性 率分别为67%、100%、86%。
➢ 用合适的剂量,1-3毫米的薄层CT靶成像观察或随访 ; (most importantly the use of thin (1–3-mm) sections , as well as appropriate exposure factors)
➢ Methods: 1)测量病灶长径,测量后对直径进行修正,计 算结节的体积;2)用肺结节分析软件;3) Vanishing ratio:窗位变化,看病灶的消失率来判断有无增大。
➢ 周围型小腺癌不同分型与CT表现有密切关系
(close correlation between CT findings and the spectrum of peripheral adenocarcinoma) ➢ 不是所有的GGN都是恶性的,尤其是GGO; 有时需要随访、PET-CT的帮助,甚至穿刺活 检(the diagnosis and management of these lesions remain problematic)
