What are the other Names for the Procedure?
- Direct Arthrography
What is Arthrogram radiology procedure? (General Explanation)
An Arthrogram is an advanced imaging technique used to evaluate a joint in the body.
- It utilizes an injection of contrast material either into the joint (Direct Arthrogram) or through the bloodstream (Indirect Arthrogram). Of the two, Direct Arthrogram is more commonly used
- In this procedure, the radiologist uses specialized imaging techniques to create a short video. They may use the following techniques:
- Continuous X-rays (fluoroscopy): A specialized film and ionizing radiation is used to generate images
- Magnetic resonance imaging (MRI): A powerful magnet and radio waves are used to generate the images
- Computerized tomography (CT): Carefully positioned X-rays around a structure permits 3-dimensional examination of the structure
What part of the Body does the Arthrogram Procedure involve?
An Arthrogram radiology procedure could involve various joints in the body, but is more commonly performed on the following joints:
Why is the Arthrogram radiology procedure Performed?
An Arthrogram radiology procedure is performed to:
- Help diagnose joint pain
- Examine structure inside the joint space
- Evaluate artificial joints
What are the Alternative Choices for the Procedure?
There are no alternatives to an Arthrogram radiology procedure.
What is the Equipment used? (Description of Equipment)
The equipment used for the procedure varies depending upon the imaging technique used by the radiologist but may include:
- A thin needle is used to inject the contrast into the joint space
- Ultrasound imaging technique using sound waves may be used to guide the needle into the joint space
Specialized imaging devices may include:
- A MRI scanner, which is a large cylinder-shaped tube that is surrounded by a circular magnet. The patient lies on the table that slides back and forth in the cylinder tube
- A continuous X-ray device (fluoroscopy) with specialized film to provide real-time images
- A CT scanner, which is a large cylinder-shaped tube surrounded by X-ray devices with specialized film to record the images
What are the Recent Advances in the Procedure?
There are no recent advances to an Arthrogram radiology procedure.
What is the Cost of performing the Arthrogram radiology procedure?
The cost of an Arthrogram procedure depends on a variety of factors, such as the type of your health insurance, annual deductibles, co-pay requirements, out-of-network and in-network of your healthcare providers and healthcare facilities.
In many cases, an estimate may be provided before the procedure. The final amount depends upon the findings during the procedure and post-operative care that is necessary.
When do you need a Second Opinion, prior to the Procedure?
- It is normal for a patient to feel uncomfortable and confused with a sudden inflow of information regarding an Arthrogram procedure and what needs to be done
- If the patient needs further reassurance or a second opinion, a physician will almost always assist in recommending another physician
- Also, if the procedure involves multiple steps or has many alternatives, the patient may take a second opinion to understand and choose the best one. They can also choose to approach another physician independently.

Prior to Arthrogram radiology procedure:
How does the Arthrogram radiology procedure work?
If the procedure is performed under CT or continuous X-rays:
- The X-rays pass through the body and are recorded on a special film
- X-rays, produced by the machine, either pass through or are deflected by parts of the body.
- If most of the X-rays pass through a structure, it appears black (such as air-filled lungs)
- If a majority of the X-rays are deflected, it appears white (as in bones)
- Many structures (tissues usually) will appear in shades of grey
- The use of contrast helps expand the joint space and allow the tissue to be seen on film
- The result is displayed in real-time on a television-like monitor for the radiologist
If the procedure is performed under MRI guidance:
- The MRI machine uses magnetic fields and radio waves to generate signals from the body
- A computer captures these signals and reconstructs the data into images
- The use of contrast changes the signal produced by the joint space, to make it more viable
How is the Arthrogram radiology procedure Performed?
The Arthrogram radiology procedure is performed in the following manner:
- The joint to be investigated is positioned in or near the scanner
- Initial images of the joint are taken
- The skin around the joint is cleaned and a small needle is used to inject a local anesthetic around the area
- After the area is numb, a small needle is used to enter the joint capsule and inject contrast material under image guidance
- The joint is manipulated and images are taken from different angles
Where is the Procedure Performed?
The Arthrogram radiology procedure is usually performed as an outpatient procedure at a hospital.
Who Performs the Procedure?
The Arthrogram radiology procedure is performed by a radiologist.
How long will the Procedure take?
The time of the procedure may vary, but if the Arthrogram procedure is performed with continuous X-rays or CT, it should take less than 45 minutes. If the procedure is performed with MRI, it may take over one hour to complete.
Who interprets the Result?
A radiologist interprets the results of the Arthrogram radiology procedure.
What preparations are needed, prior to the Procedure?
The following preparations may be needed prior to an Arthrogram procedure:
- The physician may evaluate the individual’s medical history to gain a comprehensive knowledge of the overall health status of the patient, including information related to the medications that are currently being taken
- Patients should inform their physician, if they are allergic to any medications, especially to iodine and radioactive material used in the procedure
- Women should inform their physicians if they are breastfeeding, pregnant, or if there is a chance that they might be pregnant
- The patient may be asked to avoid eating or drinking several hours before the test
What is the Consent Process before the Procedure?
A physician will request your consent for the Arthrogram procedure using an Informed Consent Form.
Consent for the procedure: A “consent” is your approval to undergo a procedure. A consent form is signed after the risks and benefits of the procedure, and alternative treatment options, are discussed. This process is called informed consent.
You must sign the forms only after you are totally satisfied by the answers to your questions. In case of minors and individuals unable to personally give their consent, the individual’s legal guardian or next of kin, shall give their consent for the procedure.
What are the Benefits versus Risks, for this Procedure?
Following are the benefits of the procedure:
- Excellent visualization of ligaments and tendons

Following are the risks of the procedure:
- As with any procedure that breaks the skin, there is a small risk of infection
- There is potential to damage the joint capsule with the injection of contrast
- Rarely, some individuals may have an allergic reaction to the contrast agent
What are the Limitations of the Arthrogram radiology procedure?
Following are some limitations to Arthrogram:
- Small or partial tears surrounding a joint may be difficult to visualize, even with arthrography
- The procedure is not capable of identifying defects such as bruising of the bones

Who will you receive a Bill from, after the Arthrogram radiology procedure?
It is important to note that the number of bills that the patient may receive depends on the arrangement the healthcare facility has with the physician and other healthcare providers.
Sometimes, the patient may get a single bill that includes the healthcare facility and the consultant physician charges. Sometimes, the patient might get multiple bills depending on the healthcare provider involved. For instance, the patient may get a bill from:
- The hospital, where the procedure is performed
- Healthcare providers, physicians, and radiologists, who are involved in the process
The patient is advised to inquire and confirm the type of billing, before the Arthrogram procedure is performed.
