Arthrography is a special procedure in which x-rays of the joint are obtained following the introduction of contrast media into the joint space. This procedure can be done on the knee, shoulder, ankle, hip, wrist or jaw.

What To Expect

You will sit or lie down with the joint to be examined under a fluoroscope(an x-ray device connected to a video monitor that can view x-ray images). The area of concern will be prepared in a sterile manner. The radiologist will inject a local anesthetic into the joint. The fluoroscope is used to insert a needle into the joint. Contrast material is sinjected the joint. After the needle is removed you may be asked to move your joint around to distribute the contrast medium. X-ray images will be obtained.

If you are having a CT or MR arthrogram, you will be transported to the CT or MR department for additional imaging.


Meet Dr. Mathew M. Merritt - One of Our Radiologists

Dr. Mathew Merritt, a native of Ft. Lauderdale, FL, has lived in Tuscaloosa since 2001. He received his undergraduate degree from University of Arkansas and his medical degree from University of Arkansas for Medical Sciences. Dr. Merritt completed his residency and a fellowship in musculoskeletal radiology at the University of Mississippi Medical Center. Dr. Merritt, while performing most radiology procedures, specializes in musculoskeletal radiology. He maintains board certification through the American College of Radiology.

“MRI arthrography is a minimally invasive two-step procedure that gives the radiologist and ordering physician a detailed look at important intra-articular structures. Many times, arthrography helps determine whether or not a particular lesion might benefit from surgery. After the procedure is explained and the patient has given consent, the puncture location is identified under fluoroscopy and the joint is injected with contrast. If you have a history of contrast allergy, please let us know and arrangements can be made. Although less sensitive, CT arthrography can be used as an option for those with contraindication to MRI.”
