My doctor suggested me to have an arthrogram scan of my knee, but I never heard of this test before. What is an arthrogram?
An arthrogram is a procedure where a needle is inserted into a joint under x-ray guidance. Then contrast is then injected into the joint. Frequently x-rays are taken to assess the joint and cartilage. This is often followed by CT or MRI where the contrast helps to identify injuries to the joint cartilage, ligaments and tendons.
