MR imaging of thoracic disk herniations.

Magnetic resonance (MR) is of value in imaging intervertebral disk disease. We present the MR findings in two patients with thoracic disk herniations who required surgical intervention. The advantages of MR over CT myelography are ease of obtaining sagittal sections, rapid assessment of the entire thoracic spine, and a high rate of patient acceptance related to the noninvasive nature of MR and lack of morbidity and complications. For these reasons, we currently rely, almost exclusively, on MR for evaluating thoracic disk disease.
