A highly F-18 fluorodeoxyglucose-avid lung nodule was stable in both size and metabolic activity over 4 months. This was most likely nonneoplastic because a true tumor would grown in volume overtime. The high level of energy consumption was contributing functional activities or by inflammatory cells. Because the speed of tumor growth is proportional to its energy consumption, we consider the higher the metabolic activity of a lesion, the less likely of malignant if it was stable in size over time.
一个高度 F-18 氟脱氧葡萄糖摄取的肺结节在 4 个月内的大小和代谢活性均保持稳定。这很可能是非肿瘤性的,因为真正的肿瘤会随着时间的推移而生长。高水平的能量消耗可能是由功能活动或炎症细胞引起的。由于肿瘤生长速度与其能量消耗成正比,如果病变的代谢活性较高,且在一段时间内大小保持稳定,则其恶性的可能性较小。
