How does a PET Scan use Radioisotope decay?
A PET scan uses radioisotope decay by detecting the pair of annihilation photons emitted during the decay process.
What does a PET scan demonstrates the detection of?
A PET scan demonstrates the detection of metabolic activity in cells. It is commonly used in detecting cancer, Alzheimer's disease, and other conditions where there is abnormal cell activity.
What brain imaging method requires the injection of a radioactive substance?
Single-photon emission computed tomography (SPECT) is a brain imaging method that requires the injection of a radioactive substance. This substance emits gamma rays that can be detected by a gamma camera to produce detailed images of brain activity.
What is metabolically active subcarinal lymphadenopathy?
Metabolically active subcarinal lymphadenopathy refers to enlarged lymph nodes in the subcarinal region of the chest that are taking up increased glucose on a positron emission tomography (PET) scan, indicating increased metabolic activity. This finding is commonly associated with conditions such as infection, inflammation, or malignancy in the chest area. Further evaluation with imaging studies or biopsy may be needed to determine the underlying cause.
A scanning technique that combines nuclear medicine and chemical analysis to enable physicians to observe the function of certain organs of the body?
