Dr Jones & Partners has multiple MRI scanners in metropolitan Adelaide, Mt Barker and Whyalla. We have a highly experienced team of MRI technicians.
More information regarding MRI can be found in the MRI section.
Sometimes your doctor will request an arthrogram as part of your MRI examination. It is very important to mention this when booking as it requires additional booking of the radiologist and screening unit. This test can only be done at selected sites.
An arthrogram injection is an injection of contrast dye into a joint to allow better visualisation of internal joint structures during the MRI examination. The study will be reported by a radiologist and the results sent to your doctor.
The joint may be injected in X-ray or ultrasound. The skin will be cleaned with antiseptic. The radiologist inserts a fine needle into the joint that your doctor has asked us to inject using an aseptic technique. We use x-ray or ultrasound to guide the placement of the needle safely and accurately into the correct position.
X-ray contrast is usually injected into the joint to confirm that the needle is in the correct location.
For an MRI arthrogram another contrast (gadolinium) is also injected to distend the joint and you are then moved to the MRI machine for your scan.
You may experience a feeling of fullness and/or tightness as the joint is distended with fluid, but the procedure is usually well tolerated.
Risks / Side effects?
Arthrogram injections are generally very safe.
Potential risks include infection within the soft tissues or joint.
If X-ray contrast is administered there is a small risk of allergic reaction. This includes flushing, hives and difficulty breathing. Severe reactions are rare and life-threatening reaction extremely rare (1 in 170,000).
Before your Scan
No specific preparation is required and you may eat and drink before and after the procedure. If you are on any special drugs or have diabetes and are on insulin, take your usual medicines and diet.
Please inform us if you are on medication to thin your blood (eg. Warfarin, Aspirin or Clopidogrel), have an iodine allergy or are pregnant or breastfeeding.
To be confirmed.
Any discomfort in the joint should settle within 24 hours as the contrast is absorbed.
No strenuous activity for 48 hours after the Arthrogram.
Occasionally there may be soreness or bruising at the site of the injection.
- If required, a simple analgesic such as paracetamol (Panadol) should be sufficient.
- An ice pack may also provide some relief.
Infection is an uncommon, but serious side effect. If you notice any fever or redness, swelling, or increased pain at the injection site after the first 2 days notify your referring doctor or call the clinic where the injection was performed immediately.
