X-Ray

X-rays are a form of electromagnetic radiation (like light); they are of higher energy, however, and can penetrate the body to form an image on film. Structures that are dense (such as bone) will appear white, air will be black, and other structures will be shades of gray depending on density. X-rays can provide information about obstructions, tumors, and other diseases, especially when coupled with the use of barium and air contrast within the bowel.

Skeleton

The skeleton consists of groups of bones which protect and move the body.

Osteogenic Sarcoma - X-Ray

This X-ray shows a malignant bone tumor (osteogenic sarcoma) of the knee. This type of tumor is usually seen in adolescents (around 15 years old). This tumor extends from the bone into the surrounding tissue.

Ewings Sarcoma - X-Ray

This X-ray shows a malignant bone tumor (Ewing's sarcoma) of the upper arm bone (humerus). This type of tumor usually occurs during childhood and adolescence.
