What it is
VFA is a low-dose X-ray view of the spine that may be performed on a DXA machine.[1]
Why it matters
A vertebral compression fracture can change fracture-risk interpretation even when a density number is not extreme.[2]
What it affects
- ISCD describes VFA as designed to detect vertebral fractures, not to diagnose all spine abnormalities.[2]
Interpretation traps
- Follow-up imaging decisions belong in clinician-guided context.[2]
