Inclusion Criteria
1. QCT and routine CT of the spine present
2. maximum time interval between QCT and routine CT of 30 days
3. all underlying diseases except multiple myeloma
4. at least one vertebral body from BWK 12 to LWK 4 present and measurable by both QCT and routine CT (i.e., no fracture, no foreign material/cement within the vertebral body)
5. for routine CT, either the raw data set (axial with max. slice thickness of 1 mm) and/or a sagittal reconstruction of the spine bony is available (sagittal with max. slice thickness of 3 mm)

- Primary Outcome Measures
Name Time Method 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 Outcome Measures
Name Time Method 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.<br>2. To analyze how the results of algorithm-based imaging data analysis differ from manual measurements by radiologists.
