PET Full Form in Medical term is Positron Emission Tomography. A PET scan is an imaging test that uses positron emission tomography. Radioactive material (a “tracer”) is used to detect illness.
A PET scan can reveal the health of many organs and tissues.
PET/CT scanners are routinely utilized because they can provide high-quality pictures by combining PET and CT data.
A PET scan employs the use of a minute dose of radioactive tracer. The tracer is intravenously (IV) administered. The inside of the elbow is a common place to insert the needle. The tracer is absorbed into the bloodstream and distributed throughout the body. The radiologist’s vision is aided by this.
The body needs time to process the tracer, so please be patient. About an hour is needed for this.
After that, you’ll lie on a little table that’ll slide inside a huge tunnel-shaped scanner. The PET is able to pick up the tracer’s signals. The impulses are converted into 3D images by a computer. Your doctor can read the images on a screen in front of them.
During the exam, you’ll need to lie flat. Errors and blurriness from motion are both possible.
