title: Is quantitative magnetic resonance imaging valuable in the assessment of trabecular bone structure in osteoporosis?
abstract: OBJECTIVE
  This study aims to evaluate the value of quantitative magnetic resonance imaging in the assessment of bone trabeculae in osteoporosis by comparing the results with dual-energy X-ray (DXA) absorptiometry.
  
  
  METHODS
  The study consisted of 85 postmenopausal women (mean age 57.2 years; range 43 to 83 years) underwent both DXA absorptiometry and lumbar quantitative magnetic resonance imaging. T2 and T2* values were calculated by magnetic resonance imaging and the results were compared with bone mineral density.
  
  
  RESULTS
  According to bone mineral density t-scores; there were 32 normal, 30 osteopenic, and 23 osteoporotic patients. T2 values of L1- L4 were different in normal with osteoporotic, and the osteopenic with osteoporotic groups. There were increased T2 values with reducing t-scores. Comparing the normal and osteopenic groups, no statistical difference was found in T2 measurements of lumbar vertebrae, except L4. T2* values of L1-L4 vertebrae were not statistically different between the study groups.
  
  
  CONCLUSIONS
  T2 measurements of lumbar vertebra on quantitative magnetic resonance imaging may be useful in evaluation of bone trabeculae in osteoporosis, and may also be helpful in differentiation of osteoporotic from normal, and osteopenic from osteoporotic patients.
