Abstract

Objectives

To assess the predictive value of the combination of bone marrow (BM) proton density fat fraction (PDFF) and liver R2* for osteopenia and osteoporosis and the additional role of liver R2*.

Methods

A total of 107 healthy women were included between June 2019 and January 2021. Each participant underwent dual-energy X-ray absorptiometry (DXA) and chemical shift-encoded 3.0-T MRI. PDFF measurements were performed for each lumbar vertebral body, and R2* measurements were performed in liver segments. Agreement among measurements was assessed by Bland-Altman analysis. Receiver operating characteristic (ROC) curves were generated to select optimised cut-offs for BM PDFF and liver R2*. Univariable and multivariable logistic regressions were performed. The C statistic and continuous net reclassification improvement (NRI) were adopted to explore the incremental predictive ability of liver R2*.

Results

Bone mass decreased in 42 cases (39.3%) and nonbone mass decreased in 65 cases (60.7%). There were significant differences among the age groups, menopausal status groups, PDFF > 45.0% groups, and R2* > 67.7 groups. Each measurement had good reproducibility. The odds ratios (95% CIs) were 4.05 (1.22–13.43) for PDFF and 4.34 (1.41–13.35) for R2*. The C statistic (95% CI) without R2* was 0.888 (0.827–0.950), and with R2* was 0.900 (0.841–0.960). The NRI resulting from the combination of PDFF and R2* was 75.6% (p < 0.01).

Conclusion

The predictive improvement over the use of BM PDFF and other traditional risk factors demonstrates the potential of liver R2* as a biomarker for osteopenia and osteoporosis in healthy women.

Key Points

• Liver R2* is a biomarker for the assessment of osteopenia and osteoporosis.
• Liver R2* improved the ability to predict osteopenia and osteoporosis.
• The intra- and interobserver measurements showed high agreement.
