Abstract

Measurements relevant to the musculoskeletal system that can be made on CT include distances and angles from the scout view, distances, angles and CT numbers from individual axial sections and more complex three-dimensional distances and angles from separate axial sections or reformatted images. Volumes can be estimated from the measured dimensions of the tissue in question or by summing the product of cross-sectional area measurements and slice spacing. CT number measurement gives rise to tissue density estimation, the accuracy of which can be improved by dual-energy scan techniques.
