F-18 2-fluoro-2-deoxy-D-glucose (FDG) positron emission tomography (PET) is useful for surveys to detect bone metastasis because of its greater specificity than bone scintigraphy. However, FDG-PET is also known to yield false-positive results in acute fractures and inflammatory lesions, and distinguishing between benign and malignant lesions is difficult, even when semiquantitative methods are used. We report a case of multiple bone metastases of gastric cancer. One of the bone lesions that was positive for FDG uptake was benign, suggesting that FDG-PET can yield false-positive results.
F-18 2-氟-2-脱氧-D-葡萄糖（FDG）正电子发射断层扫描（PET）因其比骨闪烁显像具有更高的特异性，在检测骨转移的筛查中很有用。然而，FDG-PET在急性骨折和炎性病变中也会产生假阳性结果，即使使用半定量方法，区分良性和恶性病变也很困难。我们报告一例胃癌多发骨转移病例。其中一个FDG摄取呈阳性的骨病变是良性的，这表明FDG-PET可能会产生假阳性结果。
