AbstractA technique for alleviating artifacts in excision of cadaver spines for computed tomographic (CT) study is described. It maintains distension of the thecal sac by filling the spinal subarachnoid space with gelatin containing iodinated contrast media. The excision, handling, and storage procedures described prevent all but minute amounts of air from entering the specimen and producing artifacts which can degrade the CT images. The frozen specimen can be sectioned with a band saw in any plane and correlated with the CT images. This technique allows CT-anatomic correlation of not only bony and extrathecal soft tissues of the spine, but also the intrathecal neural elements.
