Abstract

The focus of radiological efforts in osteoporosis are early diagnosis and accurate prediction of treatment outcome. The most commonly used methods are dual-energy X-ray absorptiometry (DXA) and quantitative computed tomography (QCT), which together with conventional radiographs constitute the basic diagnostic modalities. All of these have been described in detail in previous chapters. Data acquired from an individual patient are generally compared to data from an age-, sex-, and ethnicity-matched control population. The bone mass measurement predicts a patient’s future risk of fracture, and osteoporosis can be diagnosed even in the absence of a history of fracture. Which measurement sites are most appropriate for the purpose may vary depending on the specific characteristics of the individual patient. The basic and supplementary techniques employed in any given clinical case should be based on knowledge of their strengths and limitations.
