PET Scan

What is PET?

PET (Positron Emission Tomography) is a functional imaging technique used to observe metabolic processes in a human body. PET is documented as a nuclear medicine. Nowadays, CT (Computed Tomography) X-ray scan is also performed on the patient during the same session and with the same machine.

PET scan is a visualising test that permits the doctor to diagnose the ailments of the body. During the process, a dye is used which involves radioactive tracers. These tracers are vaccinated into the body through a vein in the arm. The tracer gets diluted in the body. With the help of the tracer, the doctors are able to get an idea if the internal body organs are working properly.
