Healthy and strong bones are essential for keeping active, especially as people grow older. If someone is at risk of low bone density or osteoporosis, or shows signs of subtle bone loss, doctors must be able to verify the condition before making treatment recommendations. 

That’s where a bone densitometry technologist comes in. In this position, you’ll create images using specialized X-ray equipment, which can help doctors discover issues with patients’ bone health. If the test reveals bone loss, patients and their health providers can discuss treatment options, such as medication and lifestyle changes. 


To earn credentials in Bone Densitometry using the postprimary pathway, you must maintain compliance with the ARRT Standards of Ethics and fulfill additional requirements in structured education, clinical experience, and examination. You must also meet a supporting discipline prerequisite. For Bone Densitometry, you must first be certified and registered in Radiography, Nuclear Medicine Technology, or Radiation Therapy. Your Nuclear Medicine Technology credentials may be through ARRT or the Nuclear Medicine Technology Certification Board (NMTCB).
