Abstract

Following intravenous injection of iodinated contrast medium, peripheral enhancement of the area inside the spinal canal is frequently observed by computed tomography. This may be due, at least in part, to enhancement of the cerebrospinal fluid in the spinal subarachnoid space. Our preliminary observations in human patients and in animal experiments are reported. The goal of intravenous computer assisted myelography is worth pursuing.
