Summary

Computed tomography (CT) is the top choice for orbital screening. Spiral CT offers faster scans for better contrast enhancement and reduced contrast load, ideal for evaluating childhood leukocoria, proptosis, and trauma.

Area of Science:

  • Radiology
  • Ophthalmology

Background:

  • Computed tomography (CT) is a vital imaging modality in ophthalmology.
  • Spiral CT technology offers significant advantages for orbital imaging.

Purpose of the Study:

  • To review the strengths of CT, particularly spiral CT, for orbital imaging.
  • To highlight CT's role in evaluating specific pediatric and emergency conditions of the orbit.

Main Methods:

  • General review of orbital CT applications.
  • Emphasis on spiral CT technique and its benefits.

Main Results:

  • Spiral CT enables ideal contrast enhancement with reduced contrast load due to shorter scan times.
  • CT is highly effective for screening childhood leukocoria (calcification), proptosis, and orbital trauma.

Conclusions:

  • Spiral CT has solidified its role as the preferred screening examination for orbital conditions.
  • CT provides optimal postcontrast imaging essential for routine orbital evaluation.
