A PET scan, or positron emission tomography, is an imaging test that can help diagnose biochemical or metabolic issues in your body. The scan utilises a special dye with radioactive tracers to make the diagnosis. This dye is absorbed by some tissues and organs, which lets your healthcare provider assess how they respond.
If you want to know all about what PET scan is, its uses, the procedure and possible risks, continue reading through the following sections.
A PET scan lets your doctor assess the diseases in your body’s organs and tissues. The radioactive tracers that this test uses are either inhaled, injected or swallowed, depending on which part of the body is examined. The tracers allow your doctor to observe the functioning of your organs and tissues.
Because some biological tissues and diseases have a higher level of chemical activity than others, the tracer collects areas with higher chemical activity. On the PET scan, these diseased areas appear as bright spots.
Before the imaging test, your doctor will brief you on the PET scan procedure. You should tell your doctor about all the medications you take.
Additionally, consider following these prep tips:
The process takes about two hours, and most patients do not need to stay overnight. It includes:
The test is totally painless. However, you may feel anxious if you are afraid of small spaces. Consider informing the technician if you are worried about this.
A PET scan test is a useful way to detect various diseases. Some of these include:
In cancer patients, the test can also help assess whether the cancer has spread, if the chemotherapy is working, and check for any disease recurrence.
Some side effects are observed in the case of pregnant women.
The scan uses radioactive tracers, the effect of which is minimal. However, you should always discuss the possible risks with your doctor. It is possible to develop allergic reactions due to the tracers. Tell your doctor if you are allergic to aspartame, iodine or saccharine.
Unless your provider advises you otherwise, you can go about your day normally after the test. To help your body rid itself of the tracer, you should consume plenty of liquids.
