title: [The place of computed tomography and magnetic resonance tomography in the diagnosis of bone sequestra].
abstract: Conventional radiographs of 45 patients with chronic osteomyelitis, mostly of posttraumatic origin, were compared with computed tomography (CT) and operative findings. In addition, magnetic resonance imaging (MRI) was performed in 6 of these patients. In 28 patients (65%) bony sequestra were identified and in most cases histologically confirmed by surgical exploration. CT proved to be the method of choice for the preoperative diagnosis of sequestra in patients with chronic osteomyelitis. MRI provided no significant additional diagnostic information, its advantage appears to be a more detailed and accurate imaging of the extent of the intra- or extraosseous inflammation, thereby facilitating surgical planning.
