Pet Scan (Definition)

Pet scans most often use a radioactive form of glucose, the energy source for most of the cells in our bodies. The pet scanner can detect and measure how much of the radioactive glucose analog, f-18 fdg, is in a particular organ or region. The areas using more glucose are hyper metabolic and generally more worrisome. Our brains and sometimes hearts prefer glucose as food, making ...Read more

My husband has a melanoma on the right side of his stomach. Blood work, X-ray and pet scan are normal. Does that mean it is not nessery for a node biopsy?

Complete the workup: Get the pet scan and any other labs and tests your health care provider thinks are necessary. Unexplained weight loss is a sign of cancer. Lumps and tenderness need to be explained too. Get all the information possible, perhaps including a biopsy, so a proper plan of action can be determined. ...Read more

Got results for PET scan on lung nodules. Nodules are "undetermined" cuz of size but parotid glands on both side of neck showed "hot".  Any relation?

No relation: Parotid glands can have chronic inflammation which will show up on a PET scan just like tumors do. But it is unlikely to be anything significant that should worry you. You can ignore it for the time being. ...Read more

What are pet scans? What exactly is a pet scan?

Positron Emission: These studies are done by injecting a special "dye" that is attached to a specific molecule. Most of the pet today is done using FDG (a glucose/sugar look-a-like molecule). Wherever this molecule is used/concentrated, the pet scan is brighter. Hence, tumors/infections (which use a lot of energy/sugar/fdg) are bright on such studies.
