Arthrogram: Joint Contrast Imaging Explained
Some joint problems hide from plain MRI — a torn labrum can look like normal tissue. An arthrogram injects contrast directly into the joint, forcing every crevice of cartilage and ligament into view.
An arthrogram injects contrast dye into a joint — shoulder, hip, wrist, or jaw — then images it with MRI, CT, or X-ray to reveal labrum tears, ligament injuries, and cartilage damage that plain scans miss. The injection is done with numbing medicine under imaging guidance, followed by the scan itself. Expect mild post-injection soreness for a day or two.
Why would I need an arthrogram?
Shoulder pain that keeps coming back after a normal-looking MRI (suspected labral tear), hip pain with mechanical symptoms, wrist ligament injuries, and jaw-joint (TMJ) problems. The arthrogram exists because fluid contrast separates structures that otherwise touch on imaging — a torn labrum fills with dye and becomes unmistakable.
What happens during an arthrogram?
The radiologist cleans the skin, numbs it with a local anesthetic, and — watching with ultrasound or X-ray — guides a thin needle into the joint space. Contrast flows in; you may feel fullness or pressure as the joint distends, sometimes briefly strange but not sharp. The needle comes out, and you proceed directly to the MRI or CT scanner — the contrast stays in the joint for the imaging that follows.
Which joints get arthrograms, and with which scanner?
| Joint | Common use | Typical follow-up scan |
|---|---|---|
| Shoulder | Labral tears (SLAP), instability | MRI |
| Hip | Labral tears, impingement | MRI |
| Wrist | Ligament and TFCC tears | MRI or CT |
| Jaw (TMJ) | Disc displacement, joint degeneration | MRI (open/closed mouth views) |
| Ankle | Ligament injuries, impingement | MRI or CT |
How do I prepare and recover?
Preparation is simple: no fasting, take medications normally, arrange nothing special unless your facility pairs it with sedation. Recovery: the joint may ache or feel swollen for 24–48 hours — ice and over-the-counter pain relief usually suffice, and skip strenuous use of that joint for a day or two. Report fever, worsening swelling, or unrelenting pain rather than toughing it out.
Does an arthrogram hurt?
The numbing injection stings, the joint distension feels like deep pressure, and the scan that follows is painless. Most patients rate it uncomfortable rather than painful — and it replaces what would otherwise be diagnostic uncertainty or surgery.

Is an arthrogram the same as a cortisone injection?
No — an arthrogram injects contrast for imaging. Therapeutic injections (cortisone, hyaluronic acid) are different procedures, sometimes done at the same visit for separate reasons.
Why do I need an MRI after the injection?
The contrast stays inside the joint and outlines structures for the scanner. The injection without the scan diagnoses nothing; the pair is one test in two acts.
Can I drive after an arthrogram?
Usually yes, unless you took sedation. A sore joint for a day or two does not bar driving.
How accurate are MR arthrograms?
They are the reference standard for labral and certain ligament injuries — often the deciding image between physiotherapy and surgery.
What if I am allergic to contrast?
Tell the team beforehand. Joint contrast reactions are uncommon, and alternatives (including diluted formulations or CT with different agents) exist.
How soon can I exercise after an arthrogram?
Light use next day; full activity typically within 2–3 days. Your discharge sheet gives joint-specific guidance.
