Opportunistic use of lumbar computed tomography and magnetic resonance imaging for osteoporosis screening
Authors' conclusion
Opportunistic use of CT and MRI can simply distinguish patients with OP, which are expected to be potential alternatives to T-score for the osteoporosis screening.
Study context
- Population
- Lumbar spine surgery patients who received lumbar quantitative CT (QCT) and magnetic resonance imaging (MRI)
- Participants
- 109 patients
- Comparison
- Computed tomography (CT)-based Hounsfield unit (HU) value vs MRI-based vertebral bone quality (VBQ) score for identifying osteoporosis, against QCT
- Outcome
- Diagnostic performance (AUC) for OP, based on QCT results
Methodological detailsretrospective
- Retrospective
Performance
As reported in the abstract
Diagnostic performance for OP (AUC)
| Test or model | AUC | Diagnostic threshold |
|---|---|---|
| HU value | 0.959 | 97.06 |
| VBQ score | 0.880 | 3.08 |
AUC
HU value0.959
VBQ score0.880
Diagnostic threshold
HU value97.06
VBQ score3.08
Further findings
HU value and VBQ score in osteoporosis (OP) vs non-OP patients
- HU value significantly lower in the OP group
- VBQ score significantly higher in the OP group
