Molecular Imaging
            Molecular imaging enables the 
visualization of the cellular function by providing detailed pictures of
 what is happening inside the body at the molecular and cellular level. 
Unlike other diagnostic imaging procedures that offer anatomical 
pictures, molecular imaging allows physicians to see how the body is 
functioning and to measure its chemical and biological processes.
Positron
 emission tomography (PET) is a specific type of molecular imaging 
technique that provides physicians with information about the 
performance of tissues and organs. PET is often used in combination with
 computerized tomography (CT) imaging. It uses a scanner and a small 
amount of radiopharmaceutical that is injected into a patient's vein to 
assist in making detailed, computerized pictures of areas inside the 
body.
PET is often used to evaluate:
- Bone disorders
 - Cancer
 - Effectiveness of treatments
 - Gastrointestinal disorders
 - Heart conditions
 - Kidney and thyroid disorders
 - Lung disorders
 - Neurological diseases such as Alzheimer's and multiple sclerosis
 
The PET Group has four subcommittees: Coverage, Coding and Payment, Advocacy and Education, Value and Evidence and Regulatory.
Molecular
 imaging drives effective patient care through screening, diagnosis, and
 treatment. Members develop Standards and provide technical advice for 
PET and SPECT (single-photon emission computerized tomography) scanners.
 Through the PET Group, Members engage legislative and regulatory 
decision-makers and build relationships with clinicians and patient 
organizations.
