Diagnostic imaging in patients with vertebral compression fractures

Area of Science:

• Radiology
• Orthopedics
• Oncology

Background:

• Osteoporotic vertebral fractures (OVF) and metastatic vertebral fractures (MVF) often present similarly, posing diagnostic challenges.
• Radiography is insufficient for detailed assessment of demineralization and soft tissue involvement in vertebral fractures.

Purpose of the Study:

• To delineate key Magnetic Resonance Imaging (MRI) findings differentiating OVF from MVF.
• To evaluate the diagnostic accuracy and reproducibility of MRI signs for vertebral fractures.

Main Methods:

• Review of diagnostic imaging techniques for vertebral fractures.
• Analysis of specific MRI features, including intravertebral fluid, edema, vertebral deformities, soft tissue masses, and pedicle signal intensity.

Main Results:

• MRI is the preferred modality for diagnosing vertebral fractures.
• Key indicators for OVF include intravertebral fluid/fluid signal, vertebral deformities without edema, and advanced patient age.
• Distinctive signs for MVF include soft tissue mass and pedicle intensity signal asymmetries.
• The reproducibility of these diagnostic findings in clinical practice is moderate.

Conclusions:

• MRI offers superior diagnostic capability over radiography for vertebral fractures.
• Specific MRI findings can help distinguish between osteoporotic and metastatic causes of vertebral compression fractures.
• Further research may be needed to improve the reproducibility of these MRI findings in clinical settings.
