Indications for orbital imaging by the oculoplastic surgeon

Area of Science:

• Ophthalmology
• Radiology
• Medical Imaging

Background:

• Oculoplastic surgeons utilize orbital imaging (CT and MRI) to diagnose various conditions.
• Understanding the specific indications for each imaging modality is crucial for efficient patient management.

Purpose of the Study:

• To determine the primary indications for ordering orbital imaging (CT vs. MRI) by oculoplastic surgeons.
• To assess the correlation between the surgeons' clinical indications and the radiologists' final diagnoses.

Main Methods:

• Retrospective review of imaging requisitions and radiology reports.
• Analysis of data from 735 patients who underwent CT or MRI scans ordered by 4 oculoplastic surgeons between March 2006 and March 2009.

Main Results:

• CT scans were predominantly ordered for thyroid disease (most common), orbital tumors, and inflammatory conditions, and frequently for trauma and suspected foreign bodies.
• MRI scans were most commonly indicated for orbital tumors, followed by inflammatory disease and thyroid disease.
• A total of 632 CT and 223 MRI scans were analyzed.

Conclusions:

• CT is favored for trauma and foreign body evaluation, while MRI is preferred for suspected orbital tumors and inflammatory processes.
• The study highlights distinct preferences for CT and MRI based on suspected orbital pathologies in oculoplastic practice.
• Comparing clinical indications with radiological diagnoses provides insights into imaging utility.
