Positron emission tomography (PET)
A nuclear medicine imaging technique that uses radioactive isotopes to assess physiological functions.
Radio-isotope
An unstable isotope that emits radiation as it decays.
FDG
Fluorodeoxyglucose; a glucose analog used in PET scans to highlight areas of high metabolic activity.
Hot spot
An area of increased metabolic activity identified in a PET scan.
Technetium-99
A radio-isotope commonly used for bone scans to evaluate the skeleton and heart.
Iodine-125
A radio-isotope used in the treatment of thyroid cancer.
Xenon
A gas used in pulmonary ventilation studies to assess lung function.
Functional imaging
An imaging technique that provides metabolic or physiological information rather than structural detail.
Spatial resolution
The ability of an imaging system to distinguish small structures that are close together.
Physiology map
The end product of PET imaging that represents the functional activity of various organs.
