To investigate whether quantitative 3D ultrashort echo-time MRI (UTE-MRI) can characterize composition and microstructural deterioration in proximal femoral trabecular bone.
Approach:
Study design and participants: Prospective, single-center study of adult female volunteers. Of 106 recruited participants, 92 were included in the final cohort.
Cohorts: Participants were classified as Young Normal (<40 years; n=19), Old Normal (≥55 years; n=14), Osteopenia (n=44), or Osteoporosis (n=15), using age, clinical context, and DXA T-scores.
Imaging and measures: All participants underwent hip MRI at 3 T using dual-echo proton-density UTE and STAIR-UTE sequences. The study defined pore-to-matrix ratio (PMR) as second-echo PD-UTE signal divided by STAIR-UTE signal, and matrix index (MI) as STAIR-UTE signal divided by fi…
Interpretation:
The provided article context describes the study rationale, cohort, imaging protocols, and biomarker definitions but does not report study results.
Limitations:
The study included only adult female volunteers and was conducted at a single center.
The supplied context does not include the results or full data-analysis details.
Conclusion:
The study was designed to assess radiation-free UTE-MRI measures of proximal femoral trabecular bone; findings are not available in the provided context.
