Abstract
This chapter reviews musculoskeletal applications of CT, in particular the recently introduced extremity cone-beam CT (CBCT) with capability for weight-bearing imaging. We discuss the design, artifact correction algorithms, and imaging performance of extremity CBCT and present potential clinical applications of weight-bearing scans. The current and emerging applications of CT and CBCT in orthopedics are described, including anatomical measurements and their automation, volumetric assessment of joint space, and quantitative evaluation of bone microstructure and composition. Because of its functional (weight-bearing) and quantitative character, musculoskeletal radiology provides a fruitful ground for development of new CT technologies and CT-based biomarkers. Some of the promising recent advances are briefly discussed in the chapter: High-resolution CMOS-based extremity CBCT, robotic x-ray systems with capability for 3D imaging of weight-bearing hips and spine, and new generation of conventional CT scanners with enhanced spatial resolution.
