The clinical stage of non–small cell lung cancer as assessed by means of fluorodeoxyglucose–positron emission tomographic/computed tomographic scanning is less accurate in cigarette smokers Ayesha S.

Figure 1 Distribution of false-positive and false-negative results between smokers and nonsmokers. Positron emission tomographic/computed tomographic scan results were more often false negative in patients who were current smokers.

Figure 3 Simplified hypothesis of the affect of smoking on fluorodeoxyglucose–positron emission tomographic uptake. Smokers might have a higher background fluorodeoxyglucose uptake, resulting in a decreased maxSUV of the nodule. In this example, a nodule with a maxSUV of 10 would be reported with a maxSUV of 6 in a smoker and 8 in a nonsmoker because of differences in background uptake. maxSUV, maximum standardized uptake value.
