Imaging of infectious diseases using [18F] fluorodeoxyglucose PET.

摘要: The role of fluorodeoxyglucose positron emission tomography (FDG PET) in the diagnostic localization infectious diseases has expanded rapidly years. In general, sensitivity FDG PET depicting infections compares favorably to other modalities . It is shown be useful patients with suspected osteomyelitis, especially chronic low grade and vertebral osteomyelitis. although prosthetic joint very high, reported specificity varies considerably. experienced centers, uptake localized along interface between bone prosthesis can used diagnose infection acceptable specificity. Combined leukocyte scintigraphy scanning, however, remains standard scintigraphic method for diagnosis infected prostheses. promising results vascular graft infections, evaluation metastatic foci inpatients blood stream neutropenic patients, but further studies are needed before definitive conclusions drawn fever unknown origin (FUO), appears great advantage as malignancy, inflammation detected. Image fusion combining computed facilitates anatomical increased better guiding tests achieve a final diagnosis. conclusion, body evidence on utility FUO growing may become one preferred procedures many these diseases, when definite cannot easily achieved.
