What is this test?

Paranasal sinus MRI with intravenous contrast is an imaging test that produces detailed pictures of the air-filled spaces behind the nose and around the face. Intravenous contrast is a medication injected into a vein to help certain tissues and abnormalities appear more clearly.

Why might I need this test?

A clinician may order this scan for persistent or recurrent sinus symptoms, suspected infection or inflammation, nasal polyps, facial pain, or drainage. It may also be used to evaluate complications of sinus disease, assess nearby structures, or plan treatment or surgery.

How is the test performed?

You will lie on a table inside an MRI scanner while images are taken. If contrast is used, it is usually injected through an intravenous line in your arm or hand, and the scan may include images taken before and after the injection. The scanner makes loud knocking and ringing sounds, and a technician will guide you through the procedure.

How do I prepare for the test?

Tell your clinician about any contrast allergy, kidney disease, implanted devices, metal fragments in your body, and any possibility of pregnancy. Follow the facility's instructions and arrive with time to complete safety screening and, if needed, intravenous line placement.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Abnormal findings may include sinus inflammation, thickened lining, fluid or suspected infection, polyps, cysts, or other structural changes. MRI can also help assess the extent of disease or a mass and identify involvement of nearby tissues. The radiologist's interpretation is interpreted alongside your symptoms, examination, and other test results.

Frequently asked questions

Does this test use radiation?
No. MRI uses magnetic fields and radio waves rather than ionizing radiation.
Is intravenous contrast always required?
This test specifically includes intravenous contrast. The facility will screen for allergies and other contraindications and explain the contrast procedure before the scan.
How long does the scan take?
The exact time varies by facility and whether images are needed before and after contrast. The technologist will provide timing information and tell you what to expect during the examination.
