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.
Vascular surgery continues to evolve as new endovascular technologies, hybrid procedures and emerging applications of artificial intelligence expand how physicians can approach complex vascular disease.
