Which imaging technique should be performed in cases of suspected orbital fractures?

When evaluating suspected orbital fractures, a CT scan or MRI of the head is the preferred imaging technique due to its ability to provide detailed cross-sectional images of the bony structures, soft tissues, and any potential intracranial involvement.

CT scanning is especially valuable in emergency settings for its rapid acquisition of images, allowing for immediate assessment of complex fractures and any associated injuries to the orbit and surrounding areas. It can reveal displaced bones, a presence of hematomas, and other complications that require prompt medical intervention.

MRI, while not typically the first line for fractures, can provide excellent soft tissue detail and is useful in cases where there is concern for damage to the ocular muscles or nerves. However, the speed and accessibility of CT make it the go-to modality in trauma settings involving the orbit.

In summary, the use of a CT scan or MRI is crucial in effectively diagnosing orbital fractures and guiding subsequent management, highlighting its importance in clinical practice.
