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

Unlike the bone scan, the pet scan was not done dedicated only to check the bone. What is your cancer marker, alkaline phosphatase level? D/w your md. ...Read more

Is it ever that a bone scan pick up on dead cancer cells after one has been treated for bone cancer?

Is it ever that a bone scan pick up on dead cancer cells after one has been treated for bone cancer?

Yes and no.: The degree of tracer uptake depends on several factors such as the size and the type of tumor. Bone scan detects the bone metabolism surrounding the tumor. Usually the uptake will be proportionnal to the degree of "invasion" of the bones but sometimes a lesion which is healing can also be seen as a "hot" spot for many months because of the healing process. Serial scans are needed for evaluation. ...Read more
