| Why do we image the spine? |
|
Definition
- Patients who experience trauma
- Patients who complain of pain
- Patients who experience a disturbance in sensation or movement
- Patients who may have a malignancy |

|
Term
| Imagin Modalities of Cervical Spine |
|
Definition
- Plain films: good for anything
- CT scan: good for fracture delineation, tumors
- MRI scan: good for soft tissue, tumors and herniated discs |

Term
Views of Cervical Spine
(5) |
|
Definition
- Lateral view
- Swimmer's view
- Closed mouth A/P view
- Open mouth or odontoid view
- Bilateral obliques view |
|
|
Term
| What to look for on the lateral view of the Cervical Spine |
|
Definition
1. Count vertebral bodies
2. Alignment
3. Cervical curvature
4. Prevertebral soft tissue thickness
5. Widening between spinous processes
6. Facets
7. Predental space |
|
|
Term
| What are the 4 lines to assess on the Cervical Spin? |
|
Definition
- Anterior Vertebral Line
- Posterior Vertebral Line
- Spino-Laminar Line
- Posterior Spinous Line |
|
|
Term
Distance from the posterior aspect of the anterior arch of C1 to the most anterior portion of the odontoid (or predental space)

Term
| Importance of Swimmer's View of the Cervical Spine |
|
Definition
| Helpful view to facilitate seeing ALL 7 vertebrae |
|
|
Term
| What to look for on the AP view of the Cervical Spine |
|
Definition
1. Alignment
2. Oblique fractures |
|
|
Term
| What to look for on the Open mouth or Odontoid view of the Cervical Spine |
|
Definition
1. Widening of lateral parts of C1 relative to C2
2. Alignment of lateral margins and spinous processes
3. Fracture lines |
|
|
Term
What to look for on the Oblique view of the Cervical Spine
|
|
Definition
1. Neural foraminal narrowing
2. Alignment of facet joints |
|
|
Term
|
Definition
- Difficult to see detail due to superimposed structures on radiographs
- CT is needed for osseous structures
- MRI helpful for soft tissue |
|
|
Term
| Lumber Spine Imaging Modalities |
|
Definition
- Initial Radiographs: AP, Lateral, Obliques, and Lateral sacral views
- CT: good for disc abnormality, boney abnormality
- MRI: better for disc abnormality, bone contusion and ligamentous injury |
