Dear Idi, This does not necessarily mean that the cancer is active, the abnormal intensity of the marrow signal means that there was something that disrupted the normal marrow - such as the treated cancer. It does not mean that the cancer is active. The results of this scan will be compared to and put in context with clinical exam to evaluate the treated disease.
No cortical disruption means that the cortical area of the bone (protective outer shell around the bone) has not been disrupted by tumor.
Thank you very much. This makes me feel better for now. Waiting for answers is such a hard thing. This forum is so helpful and very much appreciated. Idi
