Abstract
Aim
The aim of this study was to assess the frequency of indeterminate 18F-fluorodeoxyglucose (FDG) accumulations on positron emission tomography (PET) and
PET/computed tomography (CT) images in patients with pelvic pathologies.
Methods
We retrospectively evaluated 536 focal FDG accumulations of 166 PET/CT examinations.
A consensus reading of PET/CT images, clinical data, and other imaging tests was the
standard of reference to assess sensitivities and specificities of PET and PET/CT.
Frequencies of indeterminate findings and intraobserver agreement were evaluated.
Conclusion
PET/CT improves the anatomic delineation and the correct assignment of physiologic
and pathologic uptake.
