Peripheral Quantitative Computed Tomography (pQCT)
pQCT (peripheral quantitative computed tomography): 3D assessment of bone structure, composition and geometry at the radius and tibia
Like the HR-pQCT, the pQCT is a 3D imaging platform used to assess bone density and micro-architecture of the bones in the forearm and lower leg.
Typical scans performed during a pQCT examination include the 4%, 30% and 66% site of the tibia. The trabecular bone density is assessed near the ankle at the 4% site, while cortical bone parameters can be assessed at the 30% and 66% sites. Muscle and adipose tissues are quantified at the 66% site.
Tibia Scan: 4% siteTrabecular bone density at 4% of the tibia
Tibia Scan: 66% siteCortical bone density, muscle density, muscle area and fat area at 66% of the tibia. Muscle density has been related to important patient outcomes, for example physical performance, hospitalisation events and falls.
