What to Know About PET Scans

What Are they?

PET scan stands for positron emission tomography scan. During the procedure, a specially formulated dye containing radioactive tracers will be injected into a vein in the arm. When the bloodstream absorbs the radioactive tracer,  the material will show up highlighted on the PET scanner. The resulting image helps the doctor assess a number of factors, including blood flow, glucose levels, and metabolic rate.

When Are They Used?

If a doctor believes a patient is exhibiting signs of a certain disease, then they may refer the individual to a radiology practice for a PET scan. Unlike other tests that examine the brain and nervous system, like CT scans and MRIs, PET scans look at the body’s underlying cellular structures. By examining these images closely, a doctor can detect the presence of a range of complex conditions, like brain tumors, seizures, heart problems, and memory disorders. Not only does it help detect the presence of a disease, but it can also lend insight as to potential treatments. For example, a PET scan can reveal how a cancer metabolizes and whether it has spread to other areas in the body.
