What is MRI PNS?
An MRI PNS (para nasal sinuses) creates a picture of the 4 paired air-filled spaces that surrounds the nasal cavity pituitary gland and surrounding the 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.
Why is MRI PNS done?
- To diagnose intracranial extension of sinonasal region due to infection or swelling.
- To detect tumor of the sinuses, abscess (pus within the tissues cavity), cellulitis (infection of the skin and tissues beneath the skin)
- To find out the condition of sinusitis (inflammation of the sinuses) or paranasal cancer/tumor/cyst.
- To look for acute or chronic rhinosinusitis (sinus infection), rhinitis (irritation & inflammation of the mucous membrane inside the nose), and adenoids (inflammation in the lymph node behind the nose).
Preparation for MRI PNS
- 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
