What is myelogram?

Answer 1

See http://www.webmd.com/back-pain/myelogram-16147 for details and what to expect.

Answer 2

A Spinal Myelogram is a procedure (usually accompanied by a CT scan afterward) in which a radiological contrast dye is injected into the spinal canal and allowed to permeate through the canal area. Several pictures are then taken using a Fluoroscope (real-time scanning X-ray machine) in different positions (you lay on a table that can be rotated 180 degrees). Once that's done, you're put into the CT tube for a detailed CT scan. The dye helps to illuminate problem areas.

CT Myelograms are usually done in cases where more detail than plain X-rays are needed, but the patient has a problem that precludes the use of an MRI scanner. Some common things are metal implants, pacemakers, non-magnetic metal implants that would cause signal diffusion, etc., something where an MRI can't be used, or in cases where a CT scan would be more detailed.

Although it requires an outpatient check-in to a hospital to be performed (due to the dye injection into the spinal canal, which requires a local anesthetic) it's not that bad of a procedure, unless you have severe disk damage.

The results are usually as good or better than an MRI.
