CT scan of bones and joints (pelvis, knee, ankle, wrist, extremities)

A bone and joint CT scan gives very precise images of bones and joints, as slices and 3D reconstructions. It can cover the pelvis, a hip, a knee, an ankle, a wrist, a hand, a foot or any other joint. It is mainly requested to analyse a complex fracture (for example one involving a joint) and plan its surgical treatment, to check that a bone has healed after a fracture or an operation, or to study a deformity, a bone lesion or advanced osteoarthritis. It is usually done without an injection. To study the cartilage or ligaments inside a joint, a CT arthrogram (see the dedicated page) or an MRI is usually preferred.
