Standardized uptake value (SUV)
The standardized uptake value (SUV) applies to PET imaging of tumors and typically uses the radioligand F18-2-fluoro-2-deoxy-D-glucose (FDG). The concentration of F18 activity reflects glucose metabolism which is increased in tumor cells and inflammation.
SUV is also known as the dose uptake r...

PET radiotracers
A PET radiotracer (also known as PET tracer) is a positron-emitting radiopharmaceutical used in positron emission tomography (PET). Each tracer consists of a positron-emitting isotope (radioactive tag) bound to an organic ligand (targeting agent). The ligand component of each tracer interacts wi...

Flip-flop fungus sign - FDG PET-CT
The flip-flop fungus sign suggests benign pulmonary disease on FDG-PET 1-4.
Lung cancer nodules demonstrate increasing FDG-avidity as the tumor grows. Lymph node spread occurs later and is therefore at an earlier stage of development and usually exhibits lower FDG-avidity 4.
Acutely, FDG-avidi...
