Final answer:
Myelography is the diagnostic procedure suitable for identifying a herniated nucleus pulposus, as it provides detailed images of the spinal cord and nerve roots.
Step-by-step explanation:
The diagnostic procedure useful in identifying a herniated nucleus pulposus is myelography. A herniated disc occurs when the nucleus pulposus protrudes through the anulus fibrosus, causing pressure and potential compression of spinal nerves. This can result in pain and/or muscle weakness in the affected areas. Myelography involves the injection of a contrast dye into the spinal canal to produce detailed X-ray images of the spinal cord and nerve roots, making it possible to see abnormalities such as a herniated disc. While alternatives like MRI also provide high-resolution images without the danger of radiation, myelography is specifically geared towards visualizing the spinal cord and spinal column structures.
