Prospective Study of Diagnostic Accuracy of Spectral CT for the Detection of Bone Marrow Edema

Recruiting

• Conditions: Fractures, Bone; Bone Marrow Edema

• Registration Number: NCT04963127
• Lead Sponsor: University Hospital Augsburg

Brief Summary

Dual-Energy/Multi-Energy/Spectral-CT can visualize bone marrow edema associated with fractures, however, current scientific evidence is mostly derived from to retrospective analyses. Our prospective study systematically analyzes the diagnostic accuracy of the visualization of bone marrow edema by including patients who are scheduled for a CT scan to exclude or further characterize a fracture. After giving informed consent, the CT scan will be performed using a dose-neutral Dual-Energy-/Multi-Energy-/Spectral-CT acquisition technique. If the patient undergoes MRI of the same region within 7 days, this scan will be used as a gold-standard for bone marrow edema. This will allow the quantification of diagnostic accuracy.
