Abstract

This chapter reviews the imaging techniques commonly used to assess bone mass and microarchitecture in rodents, paying particular attention to their advantages and disadvantages, as well as technical challenges associated with each technique. It discusses imaging techniques, such as radiographs, peripheral dual-energy X-ray absorptiometry (pDXA), peripheral quantitative computed tomography (pQCT), magnetic resonance imaging (MRI) and nanocomputed tomography (nCT). Structural measurements obtained from microcomputed tomography (μCT) or other 3D imaging techniques are strongly dependent on a number of technical issues associated with the analysis, including (i) the scan resolution (voxel size), (ii) the segmentation algorithm and threshold used to delineate soft tissue from bone, (iii) the skeletal site(s) and volumes of interest, and (iv) calibration of the system using density phantoms. Assessment of skeletal mass and morphology in rodents via nondestructive imaging is an important component of current investigations aimed at improving our understanding of musculoskeletal development, growth, adaptation, and disease.
