Protocol Optimization in CT for the Quantification of BMD
Protocol-optimization in Computed Tomography for the Quantification of Bone Mineral Density (BMD)
Source: ClinicalTrials.gov · Last updated 13 Jan 2026
Brief summary (registry, in English)
Bone mineral density is an important measurement to detect osteoporosis. The goal of this clinical trial is to compare bone mineral density measurements in CT examinations and DXA scans. The main question it aims to answer is: * How good is the measurement of bone mineral density in the new photon-counting CT in comparison to DXA * How can we optimize the CT scan for bone mineral density Participants will undergo: * Clinically indicated CT scan on day of inclusion * Study related DXA scan on a separate appointment
