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).
