Name of the Procedure:

Radiologic Examination of the Sacroiliac Joints, Less Than 3 Views

Summary

A radiologic examination of the sacroiliac (SI) joints is an imaging test that uses X-rays to create detailed pictures of the SI joints, which are located in the lower back where the sacrum meets the iliac bones. This procedure involves taking fewer than three X-ray images to assess the joints.

Purpose

The primary purpose of this examination is to diagnose conditions affecting the sacroiliac joints, such as arthritis, inflammation, injury, or structural abnormalities. The goal is to identify the cause of lower back and pelvic pain, guiding appropriate treatment.

Indications

• Persistent lower back or pelvic pain
• Suspected sacroiliitis (inflammation of the SI joints)
• Evaluating arthritis or other degenerative joint conditions
• Trauma or injury to the lower back
• Unexplained pain that may originate from the SI joints

Preparation

• Typically, no special preparation is required.
• Patients may be asked to remove any metal objects or clothing that could interfere with the X-ray imaging.
• It is important to inform the healthcare provider of any recent surgeries or medical conditions.

Procedure Description

1. The patient will be positioned on the X-ray table by a radiologic technologist.
2. Depending on the views needed, the patient may lie down flat, turn on their side, or be positioned at an angle.
3. A lead apron may be placed over parts of the body not being imaged to protect from radiation exposure.
4. The X-ray machine will be positioned over the sacroiliac joints.
5. The technologist will take the necessary X-ray images, ensuring that fewer than three views are captured.
6. The entire process is usually quick and painless.

Duration

The procedure typically takes about 15-30 minutes.

Setting

The examination is performed in a radiology department, hospital, or outpatient imaging center.

Personnel

• Radiologic Technologist
• Radiologist (for interpreting the images)

Risks and Complications

• Minimal radiation exposure with negligible risk.
• Rarely, discomfort from positioning during the procedure.

Benefits

• Provides valuable diagnostic information about the sacroiliac joints.
• Helps in determining the cause of lower back and pelvic pain.
• Aids in formulating an effective treatment plan.

Recovery

• No recovery time is needed as the procedure is non-invasive.
• Patients can typically resume normal activities immediately after the examination.
• Follow-up with the referring physician to discuss the results and next steps.

Alternatives

• MRI or CT scans for more detailed imaging if needed.
• Physical examination and clinical tests.
• Ultrasound to assess soft tissue structures around the SI joints.

Patient Experience

• Generally painless with minimal discomfort.
• Brief periods of holding still and specific positioning may be required.
• The radiologic technologist will assist in ensuring patient comfort and correct positioning throughout the procedure.
• Pain management measures are generally unnecessary due to the non-invasive nature of the examination.
