[Validity of nuclear magnetic resonance tomography in evaluation of the traumatized intervertebral disk].

The validity of the magnetic resonance imaging (MRI) in the diagnosis of injured intervertebral discs was examined by a prospective diagnostic study. The golden standard being intraoperative discography. The examinations were carried out on both intervertebral discs adjoining the fractured vertebral body. There were 27 patients with 54 injured discs. The sensitivity of the MRI as a noninvasive method is 96%, the specificity is 75%. These results comply with a validity of 88%.
