A positron emission tomography (PET) scan refers to an imaging test that allows a doctor to check for disease in the body. It’s a type of nuclear medicine imaging. The scan uses a specific dye that has radioactive tracers. These tracers are commonly injected into a vein in the arm. The organs and tissues then absorb the tracer.
When highlighted under a PET scanner, the tracers assist the physician to see how well the organs and tissues are working. Blood flow, oxygen use, glucose metabolism, and much more can be measured through the PET scan. This type of test is an outpatient procedure. This means that you can begin your daily activities after the test is done.
At the Vimhans PrimaMed Institute of Nuclear Medicine & Molecular Imaging, nuclear medicine images are superimposed with computed tomography (CT) to produce better views. These views provide us the information from two different exams correlated and interpreted on one image, leading to more precise information and accurate diagnoses. Our positron emission tomography/computed tomography (PET/CT) unit is able to perform both imaging exams at the same time.
