MRI Orbits With Contrast
What is MRI Orbits With Contrast?
An MRI orbit creates a picture of the skull cavity (socket where the eyeball rests) and surrounding soft tissues. The images captured during the MRI scan can be stored on an electronic device which is further printed on a film. The MRI scan is radiationless test which uses strong magnetic and radio waves to create detailed and clear 3D multiple images. The whole MRI scan procedure takes about 40-60 minutes. You may be asked to take an oral solution of the radio-contrast agent or be given the same in an injectable form for better images of the internal body structures in the MRI scan.
Why is MRI Orbits With Contrast done?
- To diagnose vision loss due to presence of optic nerve glioma (brain tumor which originates from optic nerve)
- To detect vascular (blood vessels) lesions formation of the orbit, fracture of orbital bone
- To find out optic nerve neuritis (inflammation of the optic nerve), migraine (tension-type headache), periorbital cellulitis (inflammation/infection of the eyelid).
Preparation for MRI Orbits With Contrast
- At the time of the MRI you might be asked to remove any metallic coins, jewelry, metal wrist watches, metallic keys, dentures or hearing aids as the MRI uses strong magnetic fields
- Tell your radiologist if you have metallic implants like pacemaker, cochlear implants, aneurysm clips, neuro-stimulator, surgical staples/clips or drug implants
- Pregnant women should inform their doctor about their pregnancy before going for MRI
- Get the blood urea and creatinine test done to evaluate kidney function and to ensure safety of contrast before taking up the procedure.
