Lecture 15 - Myelography
Question | Answer |
---|---|
A general term used to describe imaging procedures of the Spinal Canal where contrast medium is introduced into the subarachnoid space of the spinal canal by a lumbar or cervical puncture | Myelography |
A Lumbar or Cervical puncture to introduce contrast media into the subarachnoid space of the spinal canal | Intrathecal Injection |
When is fluoroscopy preformed during a Myelography procedure? | First to administer contrast media |
CT Myelogram best visualizes: 1 2 3 | 1. Spinal stenosis 2. Disc degeneration 3. Congenital spinal abnormalities |
Used to evaluate the soft tissues of the spine, including the intervertebral discs, spinal cord and nerves (DDD, Herniated discs, nerve root impingement, infections, tumors, and followup) | CT Myelogram |
A "disease of aging" or an age related disease - a combination of spinal problems that start with damage to the disc and eventually spread to other parts of the spine | Degenerative Disc Disease (DDD) |
Refers to nerve irritation caused by damage to the intervertebral disc | Radioulopathy |
Bony growths that form on the spine that can put pressure on spinal nerves | Bone Spurs |
An abnormal narrowing of the spinal canal | Spinal Stenosis |
Occurs when the inner nucleus pulposus of an intervertebral disc protrudes through the outer fibro-cartilaginous annulus fibrosis posteriorly | HNP - Herniated Nucleus Pulposus |
Spinal tumors that arise from cells within the spinal cords | Intramedullary Spinal Cord tumors |
Required for all types of contrast-enhanced Myelography procedures | Lumbar puncture |
Diagnosing requires an analysis of cerebrospinal fluid by Lumbar puncture | Meningitis |
Contraindications to Myelography: 1 2 3 4 | 1. Blood in CSF 2. Arachnoiditis 3. increased intrathecal pressure 4. Lumbar puncture performed within past 2 weeks |
A group of contrast media used to improve the visibility of internal body structures and pathology | MR Contrast Agents |
Patient prep for a Myelography: 1 2 3 4 5 | 1. No solid foods after midnight prior 2. Encouraged fluids 3. Some meds discontinued one or two days prior (most important anticoagulants) 4. Patient admitted to SDS as an outpatient 5. Consent form signed |
A Myelogram is considered an _______ procedure | invasive |
Cervical Myelogram Overhead Projections | X-Table Lateral and X-Table Lateral Swimmers |
Lumbar Myelogram Overhead Projection | X-Table Lateral |
What position is the patient in for the cervical Myelogram iX-Tale Lateral Swimmer's | Prone |
CR direction for the cervical myelogram | To the level of C4-C5 |
CR Direction for the Cervical Myelogram x-table lateral swimmer's | C7 |
CR direction for a lumbar myelogram | level of midaxillary |
