3D histomorphometric quantification of trabecular bones by computed microtomography using synchrotron radiation

Area of Science:

• Biomedical Engineering
• Medical Imaging
• Orthopedics

Background:

• Conventional bone histomorphometry provides quantitative bone microstructure evaluation.
• X-ray computed microtomography is a non-invasive technique for assessing trabecular bone histomorphometric indices.
• 3D imaging quantifies entire samples, unlike 2D methods with 3D extrapolation.

Purpose of the Study:

• To perform histomorphometric quantification using synchrotron 3D X-ray computed microtomography.
• To quantify bone structure across different skeletal sites.
• To investigate the impact of bone diseases on bone architecture.

Main Methods:

• Utilized synchrotron 3D X-ray computed microtomography at the SYRMEP beamline, ELETTRA.
• Acquired 3D images for quantitative analysis of bone microstructure.
• Compared bone structure in normal and pathological samples from identical skeletal sites.

Main Results:

• Achieved quantification of bone structure at various skeletal sites.
• Observed a declining bone volume fraction in pathological bones compared to normal ones.
• Demonstrated the technique's capability to assess bone disease effects.

Conclusions:

• Synchrotron 3D X-ray computed microtomography is a valuable tool for bone microarchitecture analysis.
• The findings provide a basis for comparing bone microarchitecture.
• This method can be instrumental in predicting bone fragility.
