Myelography is a specialized imaging procedure that uses contrast dye and X-rays, or more recently, computed tomography (CT), to visualize the spinal cord, nerve roots, and surrounding subarachnoid space. It requires precise injection of contrast material into the spinal canal, typically in the lumbar region. Accurate interpretation of the resulting images is essential for diagnosing various spinal conditions, such as disc herniations, spinal stenosis, tumors, and infections. This procedure necessitates a thorough understanding of spinal anatomy, potential complications, and radiation safety protocols.
Proficiency in this technique is critical for patient safety and diagnostic accuracy. Improper needle placement or incorrect contrast administration can lead to serious complications, including nerve damage, bleeding, or infection. Furthermore, the ability to discern subtle abnormalities on myelographic images directly impacts the effectiveness of subsequent treatment decisions. The development and increasing use of less invasive imaging modalities like MRI have reduced the reliance on myelography, but it retains its value in specific clinical situations, particularly for patients with contraindications to MRI, such as those with certain implanted medical devices.
