Nuclear imaging studies are noninvasive, image the whole body, and can localize a potential infectious or inflammatory cause for FUO. 5 , 14 , 19 , 37 – 40 Recently, 18F fluorodeoxyglucose positron emission tomography technology has been evaluated for guiding further invasive testing, especially in patients who have an elevated ESR or CRP level. 14 , 37 The 18F fluorodeoxyglucose is taken up by inflammatory and cancer cells because of their high rate of glucolysis. 14 , 18 , 37 Several studies examining this method in patients with FUO found diagnostic yields ranging from 16% to 69%, 15 , 37 , 38 with a high positive predictive value (93%) and negative predictive value (100%). 39 , 40 A hybrid of CT and 18F fluorodeoxyglucose positron emission tomography has a higher diagnostic yield (sensitivity of 56% to 100%; specificity of 75% to 81% 18 ). The 18F fluorodeoxyglucose has better uptake and is cleared more rapidly than older modalities (., gallium Ga 67 citrate), but it is costly and not widely available. 14
