To make an appointment for imaging at SLHV, call us at (314) 218-9654.  At each office, we have different imaging capabilities.  In Bridgeton, we can do PET or CT scans, for example, while other locations may offer ultrasounds or echocardiograms.

What is a PET scan?

A positron emission tomography (PET) scan is an imaging test that allows your doctor to check for diseases in your body.

The scan uses a special dye containing radioactive tracers. These tracers are injected into a vein in your arm. Certain organs and tissues then absorb the tracer.

When detected by a PET scanner, the tracers help your doctor to see how well your organs and tissues are working.

The tracer will collect in areas of higher chemical activity, which is helpful because certain tissues of the body, and certain diseases, have a higher level of chemical activity. These areas of disease will show up as bright spots on the PET scan.

The PET scan can measure blood flow, oxygen use, how your body uses sugar, and much more.

A PET scan is typically an outpatient procedure. This means you can go about your day after the test is finished.

In the United States, around 2 million PET scans are performed each year.

Why is a PET scan performed?

Your doctor may order a PET scan to inspect your blood flow, your oxygen intake, or the metabolism of your organs and tissues. PET scans show problems at the cellular level, giving your doctor the best view of complex systemic diseases.

PET Scan for Cardiovascular Problems

PET scans reveal areas of decreased blood flow in the heart. This is because healthy heart tissue will take in more of the tracer than unhealthy tissue or tissue that has decreased blood flow.

Different colors and degrees of brightness on the scan will indicate different levels of tissue function, helping you and your doctor decide how best to move forward.

How does the PET scan compare to other tests?

PET scans show metabolic changes occurring at the cellular level in an organ or tissue. This is important because disease often begins at the cellular level. CT scans and MRIs can’t reveal problems at the cellular level.

PET scans can detect very early changes in your cells. CT scans and MRIs can only detect changes later, as a disease alters the structure of your organs or tissues.

Detection of illness at the cellular level gives your doctor the best view of complex systemic diseases, such as coronary artery disease (CAD)

What risks are involved with a PET scan?

The PET scan involves radioactive tracers, but exposure to harmful radiation is minimal. According to the Mayo Clinic, the amount of radiation in the tracer is small, so the risks to your body are low. Still, it’s a good idea to discuss possible risks with your doctor.

The risks of the test are also minimal in comparison to how beneficial the results can be in diagnosing serious medical conditions.

The tracer is essentially glucose with the radioactive component attached. This makes it very easy for your body to eliminate the tracers, even if you have a history of kidney disease or diabetes.

People who are pregnant

Radiation is not considered safe for developing fetuses. If you’re pregnant or think you may be pregnant, you should not get a PET scan.

Other risks

Other risks of the test include discomfort if you’re claustrophobic or uncomfortable with needles. If you’re claustrophobic, you may ask your physician for medication to help you relax.

The injection may also lead to symptoms such as bleeding, bruising, or swelling.
