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 current scans). The same tracer may also be used for the diagnosis of types of dementia.
PET imaging plays a role in both diagnosis and treatment planning. It aids in the identification and staging of diseases, such as cancer, by visualizing the extent and metabolic activity of tumors. PET scans can also guide treatment decisions by assessing treatment response and monitoring disease progression.
PET scanning is also used for diagnosis of brain disease, most notably because brain tumors, strokes, and neurondegenerative diseases (such as Alzheimer's disease and Parkinson's disease) all cause great changes in brain metabolism, which in turn causes detectable changes in PET scans. PET is probably most useful in early cases of certain ...

Magnetic resonance imaging (MRI) and computed tomography (CT) scans are the most commonly used imaging technologies for diagnosis of CNS tumors. MRI provides better detail and detection of tumor-infiltrated areas. [13] Examples of CNS tumors imaged using positron emission tomography (PET).
As a result, FDG-PET can be used for diagnosis, staging, and monitoring treatment of cancers, [21] particularly in Hodgkin's disease, non-Hodgkin lymphoma, colorectal cancer, breast cancer, melanoma, and lung cancer. It has also been approved for use in diagnosing Alzheimer's disease.
This is a list of positron emission tomography (PET) radiotracers. These are chemical compounds in which one or more atoms have been replaced by a short-lived, positron emitting radioisotope. Cardiology
