An incidental PTC in a 62-year-old male patient with lymphoma. a, b Enhanced axial CT scan and fused PET/CT scan of the neck demonstrate a well-defined, hypodense right thyroid nodule (white arrow) with high FDG uptake. The FDG-avid uptake in the left side (circle) is related to patient's known lymphoma, which resolved after treatment. c, d ...
The [18 F]FDG-6-phosphate formed when [18 F]FDG enters the cell cannot exit the cell before radioactive decay. As a result, the distribution of [18 F]FDG is a good reflection of the distribution of glucose uptake and phosphorylation by cells in the body. [citation needed] The fluorine in [18 F]FDG decays radioactively via beta-decay to 18 O −.
>30% increase in 18F-FDG SUL peak, with >0.8 SUL units increase in tumor SUV peak from the baseline scan in pattern typical of tumor and not of infection/treatment effect. or Visible increase in the extent of 18F-FDG tumor uptake. or New 18F-FDG avid lesions which are typical of cancer and not related to treatment effect or infection.
3-dimensional [18 F]FDG-PET image with 3D ROI generated by a threshold based algorithm.The blue dot in the MIP image bottom right marks the maximum SUV within the ROI.. The standardized uptake value (SUV) is a nuclear medicine term, used in positron emission tomography (PET) as well as in modern calibrated single photon emission tomography (SPECT) imaging for a semiquantitative analysis.

FDG imaging protocols acquires slices with a thickness of 2 to 3 mm. Hypermetabolic lesions are shown as false color-coded pixels or voxels onto the gray-value coded CT images. Standardized Uptake Values are calculated by the software for each hypermetabolic region detected in the image. It provides a quantification of size of the lesion, since ...
The concentrations of imaged FDG tracer indicate tissue metabolic activity as it corresponds to the regional glucose uptake. FDG is used to explore the possibility of cancer spreading to other body sites (cancer metastasis). These FDG PET scans for detecting cancer metastasis are the most common in standard medical care (representing 90% of ...
"That's because women have smaller hearts, lungs, and less hemoglobin, therefore, less oxygen uptake and delivery capacity." Body composition: ...
A Patlak plot (sometimes called Gjedde–Patlak plot, Patlak–Rutland plot, or Patlak analysis) [1] [2] is a graphical analysis technique based on the compartment model that uses linear regression to identify and analyze pharmacokinetics of tracers involving irreversible uptake, such as in the case of deoxyglucose.
