摘要
18F-FDG(18F-氟代脱氧葡萄糖)PET可以反映正常机体组织和肿瘤细胞的功能状态,在对肺部病变的定性诊断、肺癌的临床分期、疗效评价、复发监测以及预后估计上都明显优于CT、MRI等形态解剖学检查,而且能间接提供瘤组织细胞分化程度和增殖潜能的判断依据,具有重要的临床应用价值。由于PET在空间分辨率上存在不足,应与其他影像学检查相结合,以提高其准确性。
As a metabolic imaging agent ,18 F-fluoro-2-deoxy-D-glucose with PET imaging can reflect the function of the cell of normal tissue and carcinoma.It exerts an important role in diagnosing lung masses,differentiating the stage of lung cancer,monitoring response to treatment and assessing for recurrence and prognosis of tumor.It also can provide useful information of the grade and proliferation of lung cancer cell.With respect of the shortcoming of its resolution,18F-FDG PET should be combined with the examinations of morphology for lesion's localization.
