Conditions
Interventions
Group 1: Patients with and without osteoporotic vertebral fracture who received CT of the spine and QCT for bone mineral densitometry as part of routine clinical practice (coverage period 2000-2022).

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Evaluation of the utility of artificial intelligence analysis for opportunistic determination of volumetric bone mineral density and comparison to QCT-based measurements in the spine | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. To gain knowledge of the utility of algorithm-based opportunistic volumetric bone mineral density measurements compared to QCT-based volumetric bone mineral density values for differentiating between patients with vs. without vertebral fractures. 2. To analyze how the results of algorithm-based imaging data analysis differ from manual measurements by radiologists. | — |
