Superiority of 18F-FDG PET compared to 111In-labelled leucocyte scintigraphy in the evaluation of fever of unknown origin.
Seshadri, N, Sonoda, L I, Lever, A M et al.·The Journal of infection·2012
This study compared two imaging tests for finding the cause of fever that doctors can't explain. One test (PET) was much better at detecting problems—finding a cause in 86% of patients—compared to the other test (leucocyte scintigraphy), which only found a cause in 20% of patients. PET scans successfully identified infections, inflammation, and other conditions causing unexplained fevers.
