CPT4 code
Name of the Procedure:
Radiologic Examination of the Sacroiliac Joints; 3 or More Views
Common Name(s): Sacroiliac Joint X-ray, SI Joint X-ray
Summary
A radiologic examination of the sacroiliac joints involves taking X-ray images from multiple angles to assess the condition of these joints, which are located where the spine meets the pelvis.
Purpose
The procedure aims to diagnose conditions affecting the sacroiliac joints, such as arthritis, inflammation, or injury. The expected outcome is to obtain detailed images that help in diagnosing the cause of pain or discomfort in the lower back and pelvic area.
Indications
- Persistent lower back pain
- Suspected sacroiliac joint dysfunction or arthritis
- History of trauma to the lower back or pelvis
- Unexplained pelvic pain
- Diagnosing inflammatory conditions such as ankylosing spondylitis
Preparation
- Usually, no special preparation is needed.
- The patient should inform the healthcare provider about any pregnancy.
- Remove any metallic objects from the body area to be examined, as they can interfere with the X-ray images.
Procedure Description
- The patient will be asked to lie on an X-ray table or stand against an X-ray machine.
- Several images will be taken from different angles; typically, this involves 3 or more views.
- The patient may need to hold their breath or remain still for short periods to ensure clear images.
- The radiologic technologist will operate the X-ray machine and guide the patient through each step.
Duration
The procedure usually takes about 15-30 minutes.
Setting
The procedure is performed in a hospital radiology department or outpatient imaging center.
Personnel
- Radiologic technologist to operate the X-ray machine
- Radiologist to interpret the images
Risks and Complications
- Exposure to a small amount of radiation, although it is generally considered safe.
- Rarely, allergic reactions to contrast material (if used) can occur.
- Discomfort from holding still during the procedure.
Benefits
- Provides detailed images of the sacroiliac joints to help diagnose pain or dysfunction.
- Non-invasive and relatively quick.
- Helps in planning effective treatment.
Recovery
- No significant recovery time is required.
- Patients can typically resume normal activities immediately after the procedure.
- Follow-up appointments may be needed to discuss the results with the healthcare provider.
Alternatives
- MRI or CT scan for more detailed imaging, especially if soft tissue evaluation is needed.
- Ultrasound for certain types of joint assessment, although less common for this indication.
- Clinical examination and blood tests for inflammatory markers.
Patient Experience
During the procedure, the patient might feel slight discomfort from lying still or holding certain positions. Post-procedure, they generally do not experience any pain or side effects.
