An MRI arthrogram uses a specialist type of X-ray and MRI scanning to investigate the causes of joint pain. It can be used to diagnose conditions affecting the shoulder, hip, knee, wrist or elbow.
In each of the following procedures, ultrasound (USS) is used to examine the area to be injected and then often used to help guide the needle into the right place. First, the injection site will be cleaned and numbed with local anaesthetic. The radiologist then watches the needle on a screen and advances it slowly to the target joint or soft tissue (often very small spaces). Once the needle is confirmed in the correct position, your therapeutic injection will be administered.
It is fine to eat and drink as normal before an USS-guided injection. Wear loose comfortable clothing on the day of your injection. Please notify your radiologist if you are diabetic, allergic to any drugs/medication and if you are taking any medication already, particularly blood thinners e.g. warfarin.
