Other Imaging Findings

• Whole Bone Scan: The goal of a whole body bone scan is to show if a cancer has metastasized to your bones.
• Positron emission tomography (PET) scan: When doing this test, a small amount of a radioactive medium is injected into your body and absorbed by the organs or tissues. This radioactive substance gives off energy which in turn is used to produce the images. PET can provide more helpful information than either CT or MRI scans. It is useful to see if the cancer has spread to the lymph nodes and it is also useful for your doctor to locate where the cancer has spread.
• Another way to detect neuroblastoma is the mIBG scan (meta-iodobenzylguanidine), but it doesn't diagnose the disease in 100% of the cases. It works like this: mIBG is taken up by sympathetic neurons, and is a functioning analog of the neurotransmitter norepinephrine. When it is radio-ionated with I-131 (a radioactive iodine), it is a very good radiopharmaceutical for diagnosis of this disease.
