- Other indications for CT C-Spine over XRay
- In most Trauma cases Cervical Spine imaging is performed with CT
- Alternatives such as Cervical Spine XRay is often inadequate with up to 20-40% False Negative Rate
- C7 difficult visualization (e.g. obese or muscular patients)
- Abnormal cervical anatomy such as Rheumatoid Arthritis or Osteoarthritis in elderly (especially C1 and C2 injuries)
- Adverse Effects
- See CT-associated Radiation Exposure
- Concentrated radiation to skin of neck and Thyroid Gland
- Efficacy: Acute Traumatic Injury
- Test Sensitivity for Fracture: 98%
- CT Cervical Spine alone with axial slices <3mm has 100% NPV for unstable Cervical Spine Injury
- May someday obviate need for C-Collar or MRI in obtunded patients (follow local guidelines)
