How does cancer show up on a PET scan?
PET scans, short for Positron Emission Tomography, can detect areas of cancer by obtaining images of the body’s cells as they work.
First, you are injected with a substance made up of sugar and a small amount of radioactive material.
PET scans are not used to screen women for breast cancer.
How is a PET scan read?
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 either swallowed, inhaled, or injected into a vein in your arm depending on what part of the body is being examined.
How accurate is a PET scan in diagnosing cancer?
PET scans, short for positron emission tomography, can detect areas of cancer by taking images of the body’s cells as they work. A study suggests that FDG-PET/CT can accurately diagnose breast cancer recurrence and is more accurate than contrast-enhanced CT scans and bone scintigraphy.
Do all cancers show up on a PET scan?
Not all cancers show up on a PET scan. PET scan results are often used with other imaging and lab test results. Other tests are often needed to find out whether an area that collected a lot of radioactive material is non-cancerous (benign) or cancerous (malignant).
