Summary
Computed tomography (CT) and magnetic resonance imaging (MRI) precisely visualize orbital abnormalities. Digital subtraction angiography (DSA) aids in diagnosing and treating vascular conditions, offering interventional options.
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.
