[Advances in MRI-based bone quality scoring systems and their clinical applications]

Area of Science:

• Orthopedics
• Radiology
• Biomedical Engineering

Background:

• Osteoporosis significantly impacts quality of life and surgical outcomes, especially in China.
• Early osteoporosis detection is crucial for patient management.
• MRI-based bone quality scoring systems have emerged as a valuable tool.

Purpose of the Study:

• To review advancements in MRI-based bone quality scoring systems.
• To explore their clinical applications in assessing bone health and predicting surgical outcomes.

Main Methods:

• Comprehensive literature review of recent studies on MRI-based bone quality scoring.
• Focus on measurement techniques, influencing factors, and clinical significance.
• Comparison with dual-energy X-ray absorptiometry (DXA).

Main Results:

• MRI bone quality scoring systems (vertebral, endplate, pedicle) show efficacy in identifying abnormal bone mass.
• These systems effectively predict postoperative complications.
• They are less affected by lumbar spine degenerative changes than DXA.

Conclusions:

• MRI-based bone quality scoring systems possess significant clinical application value.
• Current evidence primarily comes from retrospective studies, necessitating further investigation.
• Large-scale prospective studies and meta-analyses are required to solidify their clinical role.
