1. Bone X-ray examination: It is the most commonly used examination method, which can be initially diagnosed. If the tumor can be located in the epiphysis, it can also be located at the end of the metaphyseal bone. It can be located in the long bone or in the flat bone. The tumor of the adolescent osteophyte should be considered first. Chondroblastoma, and tumors of the above-mentioned osteophytes in adults should be considered as giant cell tumors of the bone.
2, histological examination: is considered to be the most accurate diagnostic method.
3, CT and nuclear magnetic resonance: early detection of diseased tissue, high accuracy.
