Bone density testing, or densitometry, is used to diagnosis osteoporosis. Highly trained and certified technologists measure the mass of bones using dual energy x-ray absorptiometry (DEXA or DXA), the industry's most commonly used method to monitor bone density.
Individuals interested in a career in densitometry must complete an accredited undergraduate degree program in radiography or a related radiation field before they can acquire the skills needed to perform bone density tests. Following the degree program, candidates can attend densitometry seminars offered throughout the year by various professional organizations. These classes provide the necessary knowledge needed to conduct densitometry.
Certification in densitometry establishes standards and ensures that technologists running and interpreting DXA scans offer the patients the best diagnosis and treatments possible. The International Society for Clinical Densitometry provides three certifications for technologists: Certified Bone Density Technologist (CBDT), Certified Clinical Densitometrist (CCD) and Certified Densitometry Technologist (CDT).
Both the CCD and CDT certifications are offered internationally through a standardized test and are good for five years. The 3-year CBDT designation, offered only in the United States and Canada, certifies that the candidate has passed a rigorous examination for performing bone scans. Maintaining certification requires ongoing education.
To work as a bone density technologist, individuals must meet state licensing requirements, which usually include the number of hours worked and education qualifications. For example, the state of Colorado requires practicing densitometrists to be trained, registered with the ARRT and hold current certification by an organization recognized by that state. Other states like Florida only require a technologist be a licensed radiation technologist. According to Payscale.com as of September 2014, most bone density technologists, or bone densitometry technicians, earn an annual salary of between $25,677 and $51,211. The BLS listed the median annual salary for radiologic technologists as $55,200 in 2013.
