There is considerable scientific knowledge about the causes, prevention, and treatment of bone disorders, but many gaps remain in this information. For example, it is not clearly understood why fractures occur in so many people. In this bone biology review, we look at some of the recent discoveries in skeletal genetics and metabolism that are expected to improve our understanding of bone health.
DXA is the most commonly used machine for BMD measurement. It is more common than other modalities such as QCT in osteoporotic patients. X-ray techs need at least a basic knowledge of DXA results interpretation. DXA results are expressed by two numbers known as T-score and Z-score.
Inherited disorders of the bones are present since the time of birth. However, certain skeletal conditions are acquired later in life. A common type of acquired disorder is a bone tumor. Bone tumors radiology is an important diagnostic method to identify malignancies of the skeleton. X-ray technologists may come across patients with bone tumors when they present to the radiology department for imaging.
