A myelogram is a diagnostic medical procedure performed to assess the condition of the spinal cord, nerve roots, and surrounding structures. It involves the injection of a contrast dye, known as a radiographic contrast agent, into the spinal canal. The contrast dye helps to outline the spinal cord and its surrounding structures, allowing healthcare professionals to visualize any abnormalities or pathologies that may be present.
During a myelogram, the patient lies on their stomach or side, and a thin needle is inserted into the spinal canal, usually at the lower back. Then, a small amount of contrast dye is injected, which flows naturally around the spinal cord and nerve roots. A series of X-rays or computed tomography (CT) scans is taken to capture images of the spinal canal and any possible abnormalities.
This procedure is commonly utilized to diagnose several spinal conditions and disorders, such as herniated discs, spinal tumors, spinal stenosis, or nerve root compression. It can provide valuable information about the location, extent, and nature of the abnormalities found in the spine. Myelograms are often performed when other imaging techniques, like magnetic resonance imaging (MRI) or CT scans, do not provide conclusive results.
Although myelograms are generally considered safe, there are potential risks associated with the procedure, such as allergic reactions to the contrast dye, infection at the injection site, or spinal headache. Therefore, it is crucial for medical professionals to evaluate the risks and benefits before recommending a myelogram to a patient.
