All of the following cellular mechanisms are responsible for malignant cells increased F-18 fluorodeoxyglucose accumulation EXCEPT:

High glucose levels may interfere with tumor targeting due to competitive inhibition of FDG uptake by d-glucose. FDG-PET study should not be recommended when the glucose level in the blood exceeds:

Before FDG administration, the patient relaxes in a waiting room to minimize muscular activity, and in so doing minimizes any physiological uptake of FDG in the muscles. Hyperventilation may cause increased uptake in the:

All of the following scintigraphic methods are often used in the diagnosis of fever of unknown origin (FUO) EXCEPT:

The majority of radiation exposure to personnel performing PET/CT procedures comes from the:

With the administration of oral contrast media for integrated Positron Emission Tomography/Computed Tomography (PET/CT) studies, CT-derived attenuation values are:

F-18 is a cyclotron-produced radioisotope with a half-life approximately of:

A 65-year-old patient is referred for a brain PET/MR study. The referring physician reports placement of a titanium alloy brain clips for an intracranial aneurysm 5 years ago. Which of the following would be the most appropriate action regarding imaging this case?

F-18 FDG uptake in tumors correlates with tumor:

Localizing metastatic disease in thyroid cancer patients with F-18 fluorodeoxyglucose (FDG) PET imaging is the primary clinical indication if:
