A whole body PET scan can take days, weeks, months or more to simulate on a modern single processor computer. There are also general use photon-tracking simulations that are tailored specifically for medical imaging, for example SimSET [Lewellen 1998] for PET and SPECT, PETSIM [Thompson 1992] for PET, and SIMIND ([SIMIND], [Ljungberg 1989]) for ...

When results of FDG-PET/CT are a study entry criterion, the baseline (eligibility) scan(s) ideally should be performed within 21 days before initiation of the therapeutic intervention. It should be noted that tumors with low FDG uptake (also see Sections 9 and 10) may not be suitable for follow-up studies of treatment response with PET.

18F-FDG PET-CT. 18F-FDG PET-CT can be useful in case of elevated thyroglobulin levels potentially due to local and/or distant recurrence, in case of suspicious lesions without 131I uptake. This technique, used for the staging of many cancers, may incidentally reveal areas of increased uptake within the thyroid - "incidentalomas" - that, in 25% ...

Positron emission tomography (PET) is a quantitative tomographic imaging technique, which produces cross-sectional images that are composites of volume elements (voxels). In PET images, the signal intensity in each voxel is dependent upon the concentration of the radionuclide within the target tissue (e.g., organ, tumor) volume.

While it is known that high levels of circulating blood glucose reduce FDG uptake, there is a paucity of scientific data to suggest a specific cutoff for abnormally high blood glucose measurements or if these subjects should be excluded from clinical trials that use FDG-PET/CT scan data.

Between 3 and 6 mCi of [18F]FES is administered in a nominal volume of 20 ml of phosphate buffered saline containing less than 15% ethanol for a single PET scan. Radiation from typical 18F PET exposure is minimal compared to the Food and Drug Administration (FDA) suggested limits (below) and are thought to present a very small risk to the ...

PBR has been imaged with positron emission tomography (PET) using [11C]1-(2-chlorophenyl-N-methylpropyl)-3-isoquinoline carboxamide (PK11195). ... had highest levels of activities at late time points of the scan (Fig.1). The brain uptake of [11C]PBR28 was blocked with a receptor saturating dose of non-radiolabeled PBR28 (3 mg/kg i.v., injection ...
