[Abstract] Objective: To explore the value of routine MRI T2-weighted imaging (T2WI ) and frequency-selective saturation (FS) T2WI in evaluating osteoporosis.Materials and Methods: 88 cases were collected whose lumbar spine bone mineral density was determined by dual-energy X-ray absorptiometry (DXA) and MRI within 1 month. According to the results of lumber DXA, cases were divided into normal bone mass group, osteopenia group and osteoporosis group, osteopenia group and osteoporosis group were classified as abnormal bone mass group. MRI mean signal difference of 1-4 lumbar vertebrae in the sagittal plane T2WI and FS-T2WI among three group and the diagnostic efficacy value between normal and abnormal bone mass group were analyzed.Results: The mean signal intensity difference of normal bone mass group, osteopenia group, osteoporosis group and abnormal bone mass group were 103.95±34.08, 193.46±38.35, 206.80±34.72, 202.65±35.99 respectively. The difference among the three groups were statistically significant (F=88.19, P<0.01). The difference between normal bone mass group and osteopenia group was statistically significant (P<0.01). The difference between normal bone mass group and osteoporosis group was statistically significant (P<0.01). The difference between osteopenia group and osteoporosis group was of no statistically significant (P=0.24). The difference between normal and abnormal bone mass group was statistically significant (P<0.01). When the mean signal intensity difference was 156.15, the largest area under the ROC curve was 0.983, with the sensitivity of 93.3% and specificity of 93.0%.Conclusions: MRI mean signal intensity difference of lumbar vertebrae in T2WI and FS-T2WI can indirectly reflect the bone metabolism by detecting the content of bone fat, it has important significance to evaluate osteoporosis.
