The use of spiral computed tomography in musculoskeletal radiology of the lower limb: the calcaneus as an example

The advent of spiral (helical) computed tomography (CT) has markedly increased the speed of modern CT systems and has found a use in a variety of musculoskeletal applications. However, the limitations of the technique must be understood if examinations are to be tailored and optimised. This review puts the limitations and advantages into context by outlining how spiral CT can be applied to musculoskeletal imaging of the lower limb. Imaging of intra-articular fractures of the calcaneus serves as a timely example of how the imaging parameters can be optimised and where the technique can offer potential advantages over conventional CT.
