Quantitative Computed Tomography (QCT)

Abstract

Bone is a specialized form of connective tissue made up of organic (24%) and inorganic (76%) components. The organic component, or osteoid, is a collagen matrix containing non-collagenous proteins, and the inorganic or mineral component consists principally of calcium hydroxyapatite crystals. The adult skeleton is composed of two types of bone, compact bone (80%) and trabecular bone (20%). Compact bone forms the cortex of the bones and is found mainly in the shafts of the long bones. Trabecular or cancellous bone is found mainly in the bones of the axial skeleton (vertebral bodies and pelvis) and in the metaphyseal regions of long bones (proximal femur, distal radius).
