pQCT scans utilize computed tomography (CT) technology to assess bone density and structure, focusing on peripheral skeletal sites like the forearm. During the scan, the patient’s limb is positioned within the scanner, and X-rays are passed through the bone at multiple angles. This allows for the calculation of parameters such as cortical and trabecular bone density, bone cross-sectional area, and cortical thickness. pQCT provides detailed insights into bone geometry and strength, aiding in fracture risk assessment and monitoring bone health.
