MORPHOLOGICAL ANALYSIS OF VERTEBRAL CANCELLOUS BONE IN QUANTITATIVE-CT

The diagnostic ranking of trabecular morphology for the evaluation of osteoporosis in quantitative CT (QCT) is presented. 5 patterns of cancellous bone correlating with trabecular density may be discerned. However, these patterns may indicate osteoporotic changes in particular cases only, by confluent rarefications if the density is still within the normal range. There is neither a predictive value for the degree of spontaneous or therapy-induced bone loss, nor for therapy response. The trabecular appearances remain unchanged in short term even under strong quantitative changes and are therefore of no value for follow-up.
