CONTENT DESCRIPTION

The advent of new cone beam techniques and adaptation of fan beam machines allow image acquisition in a standing position, making CT an excellent tool for diagnosing foot pain. Furthermore, short acquisition times make CT ideal for surgical planning and further evaluation of hoof wall pathology such as space occupying lesions e.g. keratoma.

The high spatial resolution of CT allows in-depth evaluation of bone pathology and is especially useful for the evaluation of subchondral bone resorption and periarticular pathology in the distal interphalangeal joint. The addition of intra-articular contrast helps further in the assessment of the articular cartilage, which is difficult to evaluate with other imaging modalities. 

Fan beam CT can be used for comprehensive evaluation of soft tissue pathology in the foot, especially if intra-arterial or intravenous contrast is used. This is particularly useful for assessing deep digital flexor tendon lesions in the foot, where contrast enhancement helps determine not only the presence and location of a lesion but also allows staging. 

The quick acquisition time make CT ideal for surgical planning not only for fracture repair but also for further evaluation of hoof wall pathology such as keratomas.
