An X-ray of the forearm is a safe and painless test to visualise the bones of the forearm and the soft tissues (skin and muscles) surrounding it using small amount of radiation. The area of the forearm includes the elbow, bones of the forearm (radius and ulna) and the wrist. The image is recorded on a special X-ray film. The X-ray image is black and white. Dense structures such as the bones, appear white and softer body tissues, such as the skin and muscles appear darker. The actual exposure time to radiation is usually less than a second, although the overall test may take 15-20 minutes.
