Myelogram

A myelogram is a special x-ray examination to study the spinal canal, spinal cord and the area surrounding it, which is called the subarachnoid space. The procedure involves the injection of contrast material or dye into the spinal canal. A myelogram can identify abnormalities of the spinal cord, the spinal canal within which it sits, and the spinal nerve roots connected to it. Myelography is often performed when other exams such as computerized tomography (CT) scans or magnetic resonance imaging (MRI) have not provided enough information for an accurate diagnosis to be made.
