  Purpose

The overall aim is to validate the current use of FDG PET/CT for the diagnosis of infection and inflammation and examine the usefulness of PET/CT applying also other tracers.

The results should allow us to confirm our primary hypothesis: "FDG-PET/CT is better than established methods to confirm or exclude the diagnosis of infection/inflammation".

Estimated Primary Completion Date: December 2011 (Final data collection date for primary outcome measure)
Detailed Description:

The study include several part projects, each contributing to the evaluation of the value of FDG-PET/CT in the diagnosis of infection and inflammation. The aims are to establish the diagnostic value in terms of sensitivity, specificity, positive and negative predictive values, interobserver and intraobserver variation.

Part project A FDG-PET/CT in patients with blood culture positive for staphylococcus aureus and unresolved origin of infection.

Part project B FDG-PET/CT in patients with fever of unknown origin.

Part project C FDG-PET/CT in patients suspected of vascular graft infection.

Additionally, we wish to establish an optimal imaging protocol (necessity of fasting, consequences of antibiotic therapy prior to imaging, and the need of contrast), interpretation criteria, and the value of standard uptake values (SUV).

  Eligibility

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Sampling Method:   Probability Sample
Study Population

Patients are referred for FDG-PET/CT at the Department of Nuclear Medicine, Odense University Hospital. Patients are recruited for part project A from the entire hospital through a project nurse at the Department of Infectious Diseases. Patients are recruited for part project B and part project C among all patients referred for FDG-PET/CT as per usual guidelines.
