CT Arthrography and Postoperative Musculoskeletal Imaging with Multichannel Computed Tomography

Multichannel computed tomography (MCCT) allows for rapid, thin slice acquisition and the ability to generate high mAs. This combination of features makes the modality ideal for MCCT arthrography, which requires thin, overlapping slices for robust reformatted images, and for imaging in the presence of orthopedic hardware, which necessitate high mAs. This article will explore these uses of MCCT.
