Algorithm-based qualitative and semiquantitative identification of prevalent vertebral fracture: agreement between different readers, imaging modalities, and diagnostic approaches.

Unlabelled: We compared SQ and ABQ diagnosis of VF imaged by radiography and X-ray absorptiometry. Mild ABQ VF had stronger associations with osteoporosis than mild SQ VF. Interobserver agreement (radiographic diagnosis) was better for ABQ.
