High-Resolution Peripheral Quantitative Computed Tomography (HR-pQCT)

HR-pQCT (high-resolution peripheral quantitative computed tomography): 3D assessment of cortical and trabecular density, cortical thickness and porosity, trabecular stress measures and more

DXA

The HR-pQCT is a 3D imaging platform.  While the DXA is the gold-standard for measuring BMD, the deterioration of the micro-architecture of bone is a key component of osteoporosis and is best assessed using HR-pQCT.

HR-pQCT legHR-pQCT arm

The device scans the forearm and/or lower leg to assess volumetric bone density and 3D-structure of the tibia and radius (cortical and trabecular density and thickness, trabecular separation, cortical porosity and more).

FEA can be used to calculate bone stiffness, failure load and more.

Taking bone micro-architecture into account in combination with bone density improves fracture risk prediction and may aid in the management of patients with osteoporosis.  This imaging modality uses a low dose of x-ray radiation and is otherwise non-invasive.
