myelography
C2Highly Technical / Medical
Definition
Meaning
A medical imaging technique using X-rays or other radiation to visualize the spinal cord, often with injected contrast dye.
In modern usage, the term may refer to various imaging procedures of the spinal canal, including CT or MRI-based variants, though traditionally it was strictly an X-ray procedure.
Linguistics
Semantic Notes
Specifically denotes an invasive diagnostic procedure. The root 'myelo-' refers to the spinal cord or bone marrow; in this context, it is spinal cord. Often contrasted with 'myelogram', which is the resulting image, though the terms are sometimes used interchangeably.
Dialectal Variation
British vs American Usage
Differences
Spelling is identical. Terminology and procedural details are standardised internationally in medicine. Referral phrasing may differ slightly (e.g., 'referred for a myelography' vs. 'scheduled for a myelogram').
Connotations
None beyond the technical medical context.
Frequency
Equally low-frequency in both dialects, confined entirely to medical professionals, radiologists, and related patients.

Examples
By Part of Speech
verb
British English
- The radiologist will myelograph the lumbar region.
American English
- They needed to myelograph the cervical spine.
adverb
British English
- The spine was examined myelographically.
American English
- The procedure was done myelographically.
adjective
British English
- The myelographic images showed a clear obstruction.
American English
- The myelographic contrast was introduced via a lumbar puncture.
Examples
By CEFR Level
- The doctor said the MRI wasn't clear enough, so I might need a special scan called a myelography.
- Following inconclusive MRI findings, the neurologist recommended CT myelography to better delineate the nerve root compression.
Learning
Memory Aids
Mnemonic
Think: MY ELABORATE GRAPH OF MY SPINE. 'Myelo' (spinal cord) + 'graphy' (writing/recording) = recording the spinal cord.
Conceptual Metaphor
The spine is a river, and the contrast dye is a visible tracer showing the flow and blockages.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'миелография' – a direct cognate with the same meaning. Be careful not to confuse 'myelo-' (marrow/cord) with 'myo-' (muscle). The word is highly specific; there is no simpler everyday term.
Common Mistakes
- Mispronunciation: /ˈmaɪ.ləʊ.ɡræf.i/ (incorrect stress).
- Using 'myelography' to refer to an MRI scan without contrast.
- Confusing it with 'discography' (imaging of spinal discs).

FAQ
Frequently Asked Questions
Yes, though less frequently than in the past due to advanced MRI. It remains valuable for specific cases, such as evaluating spinal hardware or when MRI is contraindicated.
Colloquially, they are often used interchangeably. Strictly, 'myelography' is the process or technique, while 'myelogram' is the resulting X-ray image.
It is an invasive procedure requiring a lumbar puncture or other spinal tap to inject contrast dye into the spinal canal.
Risks include headache, infection, bleeding, allergic reaction to contrast, and rarely, nerve injury or seizure.
