To define clinically significant postoperative changes To review MRIs of postoperative infectious conditions and recurrent disk herniations leading to reoperation To discriminate device failure upon artifacts

Methods & Materials

Postoperative fluid collection Signal change or space-occupying lesion in epidural space Space-occupying lesion in diskectomy site Bone marrow signal change Signs of device failure Summary


The major teaching points of this exhibit are : 1. To identify infectious fluid collection in operation site 2. To differentiate signal change or space-occupying lesion in epidural space between peridural fibrosis and infection 3. To determine abnormal signal intensity in diskectomy site as recurrent disk herniation 4. To define failure of devices upon artifacts
