myelography
Noun: A diagnostic imaging procedure that uses X-rays (roentgenography) to examine the spinal cord and the surrounding spaces, particularly to detect abnormalities such as lesions, tumors, or herniated discs. This procedure typically involves the injection of a contrast medium into the subarachnoid space (the area around the spinal cord) to make the structures visible on the X-ray images.
Myelography is used as a specific medical term to refer to this diagnostic test. * The doctor ordered a myelography to investigate the cause of the patient's persistent back pain and neurological symptoms. * Before the widespread use of MRI, myelography was a primary method for visualizing spinal cord compression. * The risks and benefits of myelography were explained to the patient prior to the procedure.
- The term is often used in a comparative context with modern imaging techniques.
- While magnetic resonance imaging (MRI) is now often preferred, myelography combined with computed tomography (CT) remains a valuable tool in certain complex spinal cases.
- It can be modified to specify the area of the spine examined.
- Cervical myelography focuses on the neck region of the spine.
- Myelogram (noun): The actual X-ray image or record produced by the myelography procedure.
- The radiologist reviewed the myelogram for signs of a blockage.
- Myelographic (adjective): Relating to or obtained by myelography.
- The myelographic findings confirmed the presence of a tumor.
- Spinal canal radiography (descriptive synonym)
- Contrast radiography of the spine (descriptive synonym)
- CT myelography: A modern variant where computed tomography scanning is used after the injection of contrast, providing detailed cross-sectional images.
- Myelography contrast: Refers to the dye or medium injected during the procedure.
- roentgenography of the spinal cord to detect possible lesions (usually after injection of a contrast medium into the subarachnoid space)
