How long does an MR arthrogram take?

The arthrogram itself usually takes about 15 minutes. You may then have to wait a short time before having the scan performed. A subsequent MRI scan may take 30-45 minutes, depending on the joint and the number of scans that have to be done.

How is an arthrogram performed?

In arthrography, a long, thin needle is used to put contrast dye right into the joint and a series of X-rays is taken with the joint in various positions. X-rays use small amounts of radiation to get pictures of the inside of the body.

What is the difference between arthrography and arthroscopy?

Whereas the arthrogram reproduces a black-and-white, two-dimensional picture of a spatial structure (an indirect procedure), arthroscopy provides a colored picture facilitating a three-dimensional assessment of the joint cavity, palpation, and the arthroscopic operation.

Is knee arthrogram painful?

While the arthrography procedure itself causes no pain, having to move or hold the joint still in certain positions might cause some discomfort or pain, particularly if you’ve recently had surgery or a joint injury.

What is best approach for knee injection?

Mild pain is most pronounced 4 hours after MR arthrography and disappears within 1 week after MR arthrography. Pain is more pronounced in patients younger than 30 years than in patients older than 30 years (P < . 043). There is no significant relationship between pain score and radiologist experience.

Can you shower after arthrogram?

Take any prescribed medicine (including pain medicine) as directed. Bandages were placed over the injection site after the procedure. It is important to keep the site clean and dry. You may take a shower or bath while the bandage is on.
