[Spiral CT and MR in injuries of the ankle and the foot].
Conventional radiography is the first radiological examination in injuries of ankle and foot, but often it has normal findings or it is difficult to execute for critical conditions of patients. Our purpose was to assess the value of CT and MRI in injuries of ankle and foot; we retrospectively reviewed the MR and CT images from 48 patients (age range 18-55 years), whose 16 had a major trauma with other skeletal segment lesions and the remaining a minor trauma limited to ankle and foot. On the basis of our results and experience, we think that in major trauma CT and MRI have similar findings about preoperative evaluation of fractures even if MR better identifies ischemia of fragments, subcortical contusions and lesions of ligaments, capsula or tendons. In minor trauma, MR is superior to CT because it can diagnose lesions of bone and periarticular structures that are difficult or impossible to identify with other instrumental examinations.
