What is arthrography?

Arthrography is a type of imaging procedure that is usually used to explore the internal structure of the joint, such as a knee or wrist. The contrast agent of some kind is generally injected into the joint before displaying, which helps radiographer to create clear images of the inner structure of the joint so that doctors can fully evaluate the extent of any joint damage. Most people undergo arthrography when the joint injury is suspected. The procedure usually takes place. Normally, this includes the use of X -ray imaging, although magnetic resonance imaging (MRI) can also be used. This procedure may allow doctors to explore the internal structure of the joint, even if the joint is in motion. This type of image can be used on any of the joints of the body.

Radiologists usually initiate this procedure by injection of the contrast agent into the joint. Iodine is a common choice. The body normally absorbs contrast fluid after the procedure, usually without causing serious side effects or damage. Contrasting fluid oneThe ears allow the joint structures to appear more clearly on X -ray or MRI images so that doctors can better evaluate the function of the joint.

It is usually not necessary to perform any special preparations before they perform this type of imaging test, although patients undergoing MRI are generally asked to remove any metal accessories before entering the test room. Most types of metal implants are considered MRI-SAFE, but patients are usually recommended that their doctors talk about any implants, boards, screws, peaks or clamps that they might have inside their bodies. Pregnant women and people with chronic health may not be considered good candidates for arthrography.

outpatient arthrographic procedure typically takes about half an hour to be done using an X -ray beam, although the procedure done by MRI can take more than twicefor a long time. The joint will usually be anesthetic before the procedure start. The surgeon usually removes the liquid from the joint using a syringe. This fluid is usually replaced by a contrast fluid. Patients are usually required to briefly bend the joint to help spread contrast fluid for a clearer and more detailed picture.

X -rays are usually taken in an X -ray laboratory, while MRI is usually performed in the MRI laboratory. The joint stiffening during display can help create a more useful image. Most patients will be asked to walk through several positions during the pictures. The number and type of positions will depend on the individual needs of the patient.
