Peripheral quantitative computed tomography

From Wikipedia, the free encyclopedia

In medicine, peripheral quantitative computed tomography, commonly abbreviated pQCT, is a type of quantitative computed tomography (QCT), used for making measurements of the bone mineral density (BMD) in a peripheral part of the body. It is useful for measuring bone strength.[1]

[edit] Comparison to DXA

Unlike most other common techniques for measuring BMD, a pQCT scan is able to measure volumetric bone mineral density, plus other measures such as the stress-strain index (SSI) and the geometry of the bone. DXA is only able to provide the areal bone mineral density.
