Name of the Procedure:

Ultrasound, Targeted Dynamic Microbubble Sonographic Contrast Characterization (Non-Cardiac); Initial Lesion

Summary

This procedure is a specialized ultrasound using microbubble contrast to evaluate a specific lesion outside the heart. It helps in providing detailed images of the lesion’s vascularity and dynamics, which are critical for accurate diagnosis and treatment planning.

Purpose

The procedure is primarily used to investigate non-cardiac lesions, such as those in the liver, kidneys, or other organs. The goal is to enhance the visualization of the lesion to determine its nature (e.g., benign or malignant), size, and extent, which aids in better diagnosis and management.

Indications

• Unidentified masses or tumors detected in initial scans.
• Suspicion of cancerous lesions in organs such as the liver or kidneys.
• Follow-up of previously identified lesions to monitor changes.
• Patients needing more detailed imaging than what conventional ultrasounds provide.

Preparation

• Patients may be instructed to fast for a few hours before the procedure.
• Drink plenty of water to ensure a full bladder if imaging pelvic organs.
• Inform the doctor of any allergies, particularly to contrast agents.
• A pre-procedure ultrasound may be conducted to determine the lesion’s location and characteristics.

Procedure Description

1. The patient lies on an examination table.
2. A clear gel is applied to the skin over the area to be examined.
3. A sonographer uses an ultrasound probe to capture baseline images.
4. A small amount of microbubble contrast agent is injected into a vein.
5. The sonographer continues to capture dynamic images as the contrast flows through the lesion, highlighting its vascular characteristics.
6. The entire process is non-invasive and does not typically require anesthesia.

Duration

The procedure typically takes about 30 to 60 minutes.

Setting

This procedure is usually performed in a hospital radiology department or an outpatient imaging center.

Personnel

• Radiologist or sonographer specializing in ultrasound imaging.
• Medical nurse or assistant for administering the contrast agent.

Risks and Complications

• Allergic reactions to the contrast agent (rare).
• Mild discomfort at the injection site.
• Potential but rare risk of infection from the intravenous injection.

Benefits

• Enhanced imaging details help in making accurate diagnoses.
• Non-invasive and relatively quick.
• Provides critical information without exposing the patient to radiation.

Recovery

• Most patients can resume normal activities immediately after the procedure.
• Drink plenty of fluids to help eliminate the contrast agent from the body.
• Follow any specific instructions given by the healthcare provider.

Alternatives

• MRI or CT scan with contrast: typically more detailed but involves radiation in the case of CT.
• Conventional ultrasound: less detailed imaging.
• Biopsy: more invasive and involves tissue sampling.

Patient Experience

• Patients might feel minor discomfort from the injection.
• The ultrasound process itself is painless.
• Some may experience mild warmth or a sensation of bubbles moving through their body during the injection.
• Providers will ensure patient comfort and manage any pain or anxiety during the procedure.
