However, it can be stated that if the bone infiltration is due to what might be termed a familiar bone marrow component, such as plasma cells in myeloma and white cells in leukaemia or lymphoma, then the response may be muted and only the addition of early pathological fracture may make the bone scan positive.

California Privacy Statement, While CT scans, MRIs and X-rays can detect changes in shape or mass, PET scans can detect actual physiological changes in the tissues and organs. On a CT scan, lets say you have a 1cm tumor and it doubles in size - now it all depends on the type of cancer and the type of treatment but in most cases, people will say yes - that suggests to me that the disease has progressed. The normal physiologic accumulation of 18F FDG in the body is based on glucose metabolism, which can be variable. Does FDG uptake indicate the presence of cancer? Ok, thank you.

The passive approach likes to have a baseline bone scan, for example in breast cancer[3] or prostate cancer at initial evaluation of the patient; the bone scan is then repeated, for example at six-monthly intervals independent of symptoms or signs. While this evaluation allows us to pick up on physical abnormalities or changes, it does not necessarily tell us how theyre behaving - which is a very important part of disease assessment.
