Qualitative Characteristics

Aim. To study the characteristics of the quantitative and qualitative characteristics of bone mineral density in women. Materials and methods. Quantitative computed tomography with additional quantitative and qualitative assessments was performed in 127 women of different ages without clinical signs of osteoporosis. Results. We had calculated the size and the ratio of cortical bone and spongy tissue at the lumbar vertebrae considering the density range characterized as the maximum and minimum of mineralized areas that represent not only quantitative but also qualitative state of the bone tissue. Conclusions. The obtained data can be used to assess the changes in the quality of bone in osteoporosis and osteopenia.

AbstractObjectiveBone mineral density (BMD) is a very important factor in spinal fusion surgery using instrumentation. Our aim was to investigate the utility of Hounsfield units (HU) obtained from preoperative lumbar computed tomography (CT) to predict osteoporosis coupling with data of quantitative computed tomography (QCT) and dual X-ray absorptiometry (DEXA).MethodsWe reviewed 180 patients that underwent both QCT and lumbar CT for spine surgery. HU was retrospectively calculated on the lumbar CT of 503 lumbar vertebrae from L1 to L3. Femur DEXA was performed in all patients and spine DEXA was tested in 120 patients (331 vertebrae). BMD was grouped as osteoporosis (QCT<80mg/cm3, DEXA T score≤-2.5) and non-osteoporosis (QCT≥80mg/cm3, DEXA T score>-2.5) for comparison of HU value.ResultsHU value and BMD showed significant correlations. The optima cut-off value based on QCT was higher than that of DEXA scans which had the best correlation for predicting osteoporosis. ROC curve analysis demonstrated that HU value with QCT of 146 has a sensitivity of 94.3% and a specificity of 87.5% for osteoporosis.ConclusionsSignificant correlation was found between HU measurement and BMD value. These findings provide evidence that HU measurement can be established as a means for predicting osteoporosis before spine fusion surgery with reduced radiation hazard.
