What is PET Scan and its role in diagnosing cancer?
A Positron Emission Tomography scan or PET scan is an imaging test that creates 3D pictures of your organs and tissues functioning in real time. It uses a radioactive tracer injected into your vein along with a special scanner to light up areas in your body that may show disease. PET scans are often used to diagnose and evaluate cancer, heart problems, and brain disorders.
How does PET differ from CT and MRI?
While MRI scan use magnets and CT scans use x-rays, a PET scan tracks radioactive tracers to see how your organs work. This gives it the unique ability to catch diseases in their very early stages by detecting cellular level changes. A PET scan combined with a CT scan (called a PET-CT) creates extremely detailed 3D images that allow for more accurate diagnosis.
What does a PET scan check for?
Your doctor may order one to check for cancer, heart disease, or brain abnormalities like tumors or Alzheimer’s disease. If you’ve been diagnosed with cancer, your oncologist may use PET scans before, during, and after treatment to see if the cancer has spread, evaluate treatment effectiveness, or check for recurrence.
When would a PET scan be needed?
PET scans are often used to diagnose and evaluate cancer, heart problems, and brain disorders. They can help detect diseases in early stages, evaluate cancer treatment, and check for recurrence.
How does a PET scan work?
When it’s time for your test, you’ll get an IV injection of a tracer containing a tiny, safe amount of radioactive material. You’ll wait an hour while it flows through your bloodstream and gets absorbed by tissues. Then you’ll lie inside the PET scanner (which looks like a giant donut) for about 30 minutes as it takes images.
How to prepare for a PET scan?
Make sure to follow your doctor’s preparation instructions carefully. This may include fasting for 6 hours beforehand, avoiding caffeine, and leaving jewelry at home.
What to expect during the scan?
You’ll get an IV injection of a tracer containing a tiny, safe amount of radioactive material. You’ll wait an hour while it flows through your bloodstream and gets absorbed by tissues. Then you’ll lie still inside the PET scanner for about 30 minutes as it takes images.
Risks and side effects?
The good news is that PET scans are very low risk thanks to the tiny amount of radiation. The only possible side effects are mild allergic reactions or issues for pregnant/breastfeeding women.
