Cone beam Computed Tomography (CBCT) has been widely adopted for dental 3D-imaging since the late 1990s .
Compared with multi-detector computed tomography (MDCT) imaging,
CBCT offers higher resolution with a relatively low radiation dose.
Besides use in dental and ORL applications on the first commercially available CBCT systems, modern CBCT units afford examinations in seated or lying position,
therefore permitting high resolution CBCT imaging of other body parts,
such as the wrist,
foot or ankle [2,3].
MDCT is a well established imaging modality to investigate the wrist for ligamentous tears,
cartilage abnormalities and bony lesions [4,5].
In our department,
the CBCT system has been used for musculoskeletal CT studies of extremities since its installation.
We examine the role of CBCT in arthrography of the wrist,
and more specifically illustrate the dose reduction achieved in comparison to MDCT.
