Oculoplastic surgeons tend to order computed tomography scans more frequently than magnetic resonance imaging, mainly for trauma cases and to rule out orbital foreign body, a study found.

The retrospective review examined imaging requisitions and radiology reports from four oculoplastic surgeons to determine the indications for ordering orbital imaging and for ordering CT vs. MRI.

The study included 735 patients, 449 women and 286 men, with an average age of 50 years. The oculoplastic surgeons ordered 632 CT scans and 223 MRI scans, 135 of which were follow-up scans.

The researchers determined that the most common indication for CT scan was thyroid disease, followed by orbital tumors and inflammatory disease. The most common indication for MRI scan was orbital tumors, followed by inflammatory disease and thyroid disease.
