What is this test?
MRI of the orbits is a specialized imaging technique that uses powerful magnetic fields and radio waves to produce detailed, high-resolution images of the eye sockets (orbits) and the surrounding soft tissues. This includes the eyeballs, optic nerves, extraocular muscles, lacrimal glands, and adjacent structures. This scan is crucial for evaluating a wide range of eye and orbital conditions with exceptional clarity, without exposure to radiation.
What is it used for?

• Diagnosing tumors or masses within the orbit, including benign and malignant growths affecting the eye or surrounding tissues
• Detecting inflammatory or infectious processes such as orbital cellulitis, optic neuritis, or thyroid eye disease (Graves’ orbitopathy)
• Evaluating optic nerve disorders, including optic neuritis, optic nerve compression, or demyelinating diseases such as multiple sclerosis
• Investigating causes of vision changes, unexplained eye pain, or proptosis (bulging eyes)
• Assessing trauma-related injuries involving orbital bones, muscles, or soft tissues
• Guiding treatment planning or surgical approaches for orbital pathology

Who should get this test?

• Patients experiencing vision changes, double vision, eye pain, or swelling around the eye
• Individuals with known or suspected optic nerve disease or tumors in the orbit
• Those with inflammatory conditions like thyroid eye disease or orbital cellulitis
• Patients with unexplained eye bulging, trauma, or persistent eye discomfort
• Individuals needing detailed imaging prior to orbital or neurosurgical interventions

Preparation Required:

• Standard MRI preparation — remove all metal accessories and jewelry
• No fasting or sedation typically required
• Inform the technologist of any implants or medical devices that could affect MRI safety

How is the procedure performed?
You will lie comfortably on the MRI table with your head positioned in a special coil designed for optimal imaging of the orbits. The scan takes approximately 30 to 45 minutes. You will be asked to keep still and avoid blinking excessively to ensure clear images. The procedure is painless, non-invasive, and does not involve ionizing radiation.
Risks & Safety:
MRI is a very safe procedure with no radiation exposure. Contrast agents are generally not required but may be used in select cases; risks related to contrast are rare. It is important to disclose any allergies or kidney issues beforehand.
Results:
A radiologist will carefully review the images and provide a detailed report on the condition of the orbits, including the optic nerves, eye muscles, lacrimal glands, and surrounding soft tissues. This comprehensive assessment aids your doctor in diagnosing the cause of your symptoms and planning appropriate treatment.
