Using fluoroscopic guidance and local anesthesia, a small needle is introduced to the joint space and the contrast is injected. Air may also be injected in some cases. The needle is removed and the joint is moved or exercised to cover all the internal surfaces and X-ray films are taken. MRI or CT is then commonly performed to provide further detailed cross-sectional information. The injection procedure usually only takes 10 to 15 minutes, but the subsequent X-rays and scan will take about another 1 hour to complete.
Arthrographic contrast is very easy to use and is well tolerated.
Your body will absorb and eliminate the dye over several hours. Although the arthrographic contrast is not injected into the blood stream, patients with allergy or sensitivity to X-ray dye may still be at slightly increased risk for an adverse reaction. Please notify our staff of any history of allergy prior to your arthrogram so that appropriate precautions can be taken.
