Area of Science:

  • Ophthalmology
  • Radiology
  • Medical Imaging

Background:

  • Accurate imaging is crucial for diagnosing orbital abnormalities.
  • Computerized Tomography (CT) and Magnetic Resonance Imaging (MRI) are key diagnostic tools.

Purpose of the Study:

  • To illustrate the depiction of orbital tumors using CT and MRI.
  • To discuss the roles of CT, MRI, and Digital Subtraction Angiography (DSA) in orbital imaging and intervention.

Main Methods:

  • Review of CT and MRI for delineating orbital anatomy and abnormalities.
  • Discussion of DSA for diagnosing vascular changes like carotid-cavernous fistula.
  • Overview of interventional angiography procedures.

Main Results:

  • CT and MRI effectively depict orbital tumors, inflammation, and foreign bodies.
  • DSA is essential for diagnosing orbital vascular lesions.
  • Angiography enables interventional procedures such as re-canalization and embolization.

Conclusions:

  • CT and MRI are invaluable for diagnosing a wide range of orbital pathologies.
  • DSA plays a critical role in the management of orbital vascular diseases.
  • Advanced imaging and interventional techniques improve orbital condition treatment.
