Giant cell tumor
How is a giant cell tumor diagnosed?
In addition to a taking a complete medical history and performing a full physical examination, your child's doctor may use one or more of the following tests to diagnose giant cell tumor:
- X-ray - X-rays are very useful in the diagnosis of bone tumors. They are the first diagnostic study, and they often give your doctor information regarding the need for further testing.
- Magnetic resonance imaging (MRI) -This test outlines the extent of the tumor within the bone and joint and the relationship of the tumor to the muscles, nerves and blood vessels.
- Computerized tomography scan (also called a CT or CAT scan) - A CT scan shows detailed images of any part of the body, including the bones, muscles, fat, and organs. CT scans are more detailed than general x-rays. It is used primarily to assess the chest and lung for metastatic (spreading) tumors.
- Bone scans - A nuclear imaging method used to detect bone and metastatic tumors. Bone scans can determine if there are abnormalities in other bones. This test does not distinguish between tumor, infection or fractures.
- Complete blood count (CBC) - A measurement of size, number, and maturity of different blood cells in a specific volume of blood.
