F-18 FDG PET/CT imaging artifacts

F-18 FDG PET/CT are being used in increasing numbers
in the diagnosis of the primary lesion, disease staging and
evaluation of response to therapy of various cancers due to
its high accuracy. However, PET/CT have various artifacts
which affected image quality including PET and CT AC (attenuation
correction) artifacts. For accurate identification
of malignant lesions, to characterize these artifacts is clinically
important. Our aim is to identify, to characterize and
to investigate the effect of PET/CT image quality of these
artifacts.
