Fig. 3 The DXA scanner Arrival at the Imaging Center and DXA Suite 21 The patient will be greeted by the DXA technologist who will measure the patient’s height and weight, review the information provided on the DXA questionnaire, and enter the patient’s information into the DXA computer (Fig. 4). Of note, occasionally our technologists have had to confirm the patient’s age by checking a driver’s license or other form of identification. At least on one occasion recently, the DXA results were considerably worse than expected simply because the patient had lied about her age.
More often than not, patients who present with this classic scenario have low bone mineral density due to what is called low peak bone mass, or a less than maximal amount of bone achieved during growth. This finding is actually quite common in clinical practice when densitometry testing is performed on younger individuals. To label them as having osteoporosis/high risk for fragility fractures is a misinterpretation of the meaning of T-score at that age. This patient may develop high risk for fragility fractures if her bone quality deteriorates as she gets older, but based upon her clinical history and certainly based upon FRAX® analysis (Fig.
Once the test is completed, you may resume your usual activities. The Pre-DXA Questionnaire The pre-DXA questionnaire is typically a one- or two-page form that gathers patient demographics and asks pertinent questions regarding family history, personal medical history, current diagnoses and medications, menopausal status, and diet and lifestyle choices.
