ABSTRACT
Bone density test (X-ray densitometry or DXA) is the only method of investigation for the detection of bone mineral density reduction at the earliest stage and a very valuable method for diagnosing osteoporosis and identifying risk factors for fractures. However, in certain diseases, densitometry data obtained from a densitometry study require additional interpretation to determine changes more accurately in bone mineral density in this group of patients. The article presents bone mineral density DXA data in a patient with ankylosing spondylitis and the interpretation of falsely elevated data.
Keywords: densitometry, osteoporosis, ankylosing spondylitis
