Which full term is abbreviated as PET?

• A. Measles, Mumps, Rubella
• B. Hepatitis B Vaccine
• C. Positron Emission Tomography
• D. Electrocardiogram

Answer: (C)

Positron Emission Tomography is an imaging technique that uses a radiotracer which emits positrons. The emitted positrons collide with electrons in the body to produce gamma rays, which are detected by a ring of detectors around the patient; the data are reconstructed to show a 3D image of metabolic activity. This functional information helps in areas like cancer detection and staging, brain function assessment, and evaluating heart tissue viability. The other options refer to vaccines or to a test that records the heart’s electrical activity, not imaging of metabolic processes. So the full term abbreviated as PET is Positron Emission Tomography.
