Fractures or other bone problems are not always seen on an X-ray. In these cases, other tests such as a bone scan, CT scan, or MRI may be needed to give a clearer picture. To learn more, see the topic Bone Scan.
Not all injuries to the arms or legs need X-rays. An X-ray may not be done if the doctor believes that the results would not change or affect the treatment and follow-up care.
