這是什麼
VFA is a low-dose X-ray view of the spine that may be performed on a DXA machine.[1]
為什麼重要
A vertebral compression fracture can change fracture-risk interpretation even when a density number is not extreme.[2]
它會影響哪些判斷
- ISCD describes VFA as designed to detect vertebral fractures, not to diagnose all spine abnormalities.[2]
解讀陷阱
- Follow-up imaging decisions belong in clinician-guided context.[2]
