ABSTRACT
Background- DEXA scan is gold standard tool according to WHO for evaluation of BMD but it emits ionizing radiation so it is harmful for patient and role of advance MRI imaging technique demonstrating evaluation of BMD for osteoporotic and osteopenic changes with no radiation.
Aim and Objectives– To determine the importance of DEXA and 1.5 Tesla MRI in qualitative estimation of bone mineral density in lumbar spine. The study described the correlation between the BMD and T-Score of DEXA, with MRI, T1 and T2 values
Material and method- 50 subjects underwent both DEXA and conventional MRI. T1 and T2 signal intensity values were compared with BMD and T score of DEXA scan of L3 vertebral body
Result- Both T1 and T2 signal intensities tended to increase with reducing BMD and T score.
Conclusion- An inverse relationship between BMD and T score of DEXA were found with T1 and T2 signal intensity of MRI
1.5 Tesla M.R.I can be used to evaluate bone mineral density. Since M.R.I does not use any ionizing radiation, thus it has advantage over DEXA in assessment of bone mineral density.
