Name of the Procedure:

Injection, sulfur hexafluoride lipid microspheres, per ml

Common name(s): Contrast agent injection for ultrasound
Technical term(s): Sulfur hexafluoride lipid microsphere injection, Q9950

Summary

Injection of sulfur hexafluoride lipid microspheres is used during ultrasound imaging to enhance the contrast of the images. This helps to get clearer and more detailed pictures of the body's organs and structures.

Purpose

This procedure is primarily used to improve the visualization of organs and blood flow during an ultrasound. The goal is to help detect abnormalities such as tumors, lesions, or vascular issues that may not be easily seen with a standard ultrasound.

Indications

• Poorly visualized organs on standard ultrasound
• Suspected liver lesions
• Cardiac function evaluation
• Assessment of blood flow in vessels

Preparation

• Patients may be advised to fast for a few hours before the procedure.
• Inform the healthcare provider of any allergies, especially to contrast agents.
• Routine diagnostic tests, like liver function tests, may be required beforehand.

Procedure Description

1. The patient will lie down on an examination table.
2. An intravenous (IV) line will be inserted to administer the contrast agent.
3. Sulfur hexafluoride lipid microspheres will be injected through the IV.
4. The ultrasound technician will perform the ultrasound, capturing enhanced images.
5. The procedure does not typically require anesthesia or sedation.

Duration

The procedure usually takes about 15-30 minutes, including the preparation and actual imaging.

Setting

The injection and ultrasound are generally performed in a hospital, outpatient clinic, or specialized imaging center.

Personnel

• Radiologist or ultrasound technician
• Nurse or medical assistant for IV insertion

Risks and Complications

• Mild allergic reactions (e.g., rash, itching)
• Rare severe allergic reactions (e.g., difficulty breathing, anaphylaxis)
• Injection site discomfort or bruising

Benefits

• Improved image clarity and detail
• Enhanced ability to diagnose and monitor conditions
• Immediate imaging results

Recovery

• Patients can usually resume normal activities immediately.
• Drink plenty of fluids to help flush the contrast from your system.
• Follow-up may be scheduled to discuss results and any further treatment.

Alternatives

• Standard ultrasound without contrast enhancement
• MRI or CT scans, which may provide comparable imaging
  • Pros: No need for an IV contrast agent with some MRI techniques
  • Cons: More expensive, potential exposure to ionizing radiation (CT)

Patient Experience

• Minimum discomfort from IV insertion
• Warm sensation and slight pressure during injection
• Comfort measures include a comfortable table and clear communication from staff
