Table 2.

Detection rate of 18F-FDG PET/CT in different types of diagnosed cases

Disease Fever of unknown origin Inflammation of unknown origin
Effective, n Ineffective, n Detection rate, % Effective, n Ineffective, n Detection rate, %
Infectious disease 19 12 61.3 0 1 0.0
Tumour 15 0 100.0 6 0 100.0
NIIDs 15 5 75.0 2 1 66.7
Undiagnosed 0 23 0.0 0 1 0.0

18F-FDG PET/CT = 18F-fluorodeoxyglucose positron emission tomography / computed tomography; NIIDs = non-infectious inflammatory diseases.
