What are the other advantages of spiral CT

1. Improved lesion detection leading to faster diagnosis
2. Decreased radiation dose
3. Minimized motion and partial volume artifacts
4. Capability for retrospective slice reconstruction from the volumetric data
5. Capability for virtual endoscopy
6. Improved 3-dimensional imaging
7. Optimal use of IV contrast achievable by scanning during the most effective phase
8. Decreased imaging costs
9. Reduced misregistration between adjacent slices
