Orbital CT. Current use in the MR era.
The additional advantages of spiral CT have further cemented CTs role as the screening examination of choice for the orbit. The shorter scan times permit ideal enhancement yet reduce the contrast load, providing the optimal postcontrast studies that routine imaging of the orbit requires. This article is not a comprehensive study of orbital CT, but a general review emphasizing CTs strengths, especially the evaluation of childhood leukocoria (calcification), proptosis screening, and trauma.
