PET scans, or positron emission tomography scans, are imaging checks that present molecular activity inside the body. Cancer cells may take up glucose at a higher rate, being more metabolically active. In a PET scan, a very small dose of a radioactive chemical, referred to as a radiotracer, is injected into the vein of your arm. This is necessary and unique as a result of illnesses often begin with useful adjustments within the cells.

Modern PET scanners are actually available with integrated CT scanners (PET-CT) which can create two units of precisely matched photographs. Your physician has requested a PET (positron emission tomography) scan for you.
PET-CT scans are each non-invasive and usually painless. The pictures can clearly present the a part of the physique being investigated, together with any abnormal areas, and might spotlight howÂ nicely certain functions of the body are working. The radiotracer becomes shortlyÂ less radioactive over time and can usually be passed out of your body naturallyÂ inside a number of hours.
