Table 3. The relationships between low SI patterns of OVCF according to the early T1-weighted MRI-based classification and risk factors.

Data in parentheses are case numbers and percentage. Type 1 : diffuse low SI (>90% involvement), Type 2 : globular or patchy low SI (non-band like), Type 3 : band like low SI (parallel the adjacent end plate). SI : signal intensity, VB : vertebral body, f/u : follow up
