What is a Arthrogram?
An arthrogram is a two-part exam. First, a radiologist uses live X-ray (fluoroscopy) to inject contrast directly into a joint. Then we image the joint with MRI or CT for a highly detailed look at cartilage, ligaments, and the joint capsule.
Arthrograms are commonly ordered for shoulder, hip, wrist, elbow, ankle, and knee injuries when standard imaging needs more clarity.
Before your appointment
What to wear
Comfortable, loose clothing without metal. You'll change into a gown for the injection.
Eating and drinking
Eat and drink normally before your appointment.
Medication
Tell us if you take blood thinners — your provider may have you pause them. Take other medications as usual.
What to bring
- Photo ID
- Insurance card or attorney lien paperwork
- Your prescription or referral
- A driver, especially if you're getting a hip or lower-extremity arthrogram
The day of your scan
Arrival and check-in
Arrive 30 minutes early. A radiologist will review the procedure and answer questions before the injection.
What happens during the scan
Your skin is cleaned and numbed. The radiologist uses fluoroscopy to guide a thin needle into the joint and injects contrast — you may feel pressure or fullness. Immediately afterward you'll move to the MRI or CT scanner for the imaging portion.
How long it takes
Injection takes 15–20 minutes. The follow-up MRI or CT adds 30–60 minutes.
After your scan
Rest the joint for the remainder of the day and avoid strenuous activity for 24–48 hours. Mild soreness or fullness is normal and resolves within 1–2 days. Apply ice if needed. Most patients can return to normal activity the next day.
Common concerns
Pain and soreness
Most patients describe the injection as pressure rather than pain. The joint may feel full or achy for 24–48 hours as your body absorbs the contrast.
Infection risk
Joint infection is extremely rare. Call us if you develop fever, increasing pain, redness, or swelling after the exam.
Allergic reaction
Reactions to joint contrast are very uncommon. Tell us if you've had a contrast reaction in the past.
Frequently asked questions
Does the injection hurt?
The numbing medicine stings briefly. The injection itself usually feels like pressure rather than sharp pain.
Can I drive home?
Yes for upper-extremity arthrograms. For hip, knee, or ankle arthrograms we recommend having someone drive you.
When can I return to exercise?
Avoid strenuous activity for 24–48 hours. Light activity is fine the next day.
Will I be sedated?
No. Arthrograms are done with local anesthetic only; you'll be awake the whole time.
