Name of the Procedure:

Ultrasound, targeted dynamic microbubble sonographic contrast characterization (non-cardiac); each additional lesion with separate injection

Summary

This procedure involves the use of ultrasound technology combined with a specialized contrast agent (microbubbles) to evaluate additional lesions beyond the primary one. Each additional lesion is assessed with a separate injection of the contrast agent to provide detailed imaging and characterization.

Purpose

The procedure is used to evaluate and characterize additional lesions detected in a non-cardiac ultrasound examination. It helps in distinguishing between different types of tissue and identifying abnormalities. The goal is to provide a more accurate diagnosis and guide further medical management or treatment plans.

Indications

• Detection of multiple non-cardiac lesions that require evaluation.
• Need for detailed tissue characterization to differentiate between benign and malignant lesions.
• Monitoring the progression or response to treatment of known masses.

Preparation

• Patients may be instructed to fast for a few hours before the procedure.
• Any current medications should be reviewed with the healthcare provider.
• A preliminary ultrasound without contrast may be performed to identify the target lesions.

Procedure Description

1. The patient lies on an examination table, and a conductive gel is applied to the skin over the area of interest.
2. Initial ultrasound imaging is performed to locate and assess the lesions.
3. A microbubble contrast agent is injected into the bloodstream.
4. Target lesions are identified, and the contrast agent is administered separately for each additional lesion.
5. Dynamic imaging captures the behavior of the microbubbles within the lesions to provide detailed characterization.
6. The entire process is monitored via ultrasound to ensure accurate and comprehensive assessment.

Duration

The procedure typically takes 30 to 60 minutes, depending on the number of lesions being evaluated.

Setting

The procedure is usually performed in a hospital radiology department or an outpatient imaging clinic.

Personnel

• Radiologist or a sonographer specialized in ultrasound imaging.
• Nursing staff for patient preparation and contrast agent administration.

Risks and Complications

• Mild discomfort at the injection site.
• Allergic reaction to the contrast agent (rare).
• Minor risk of infection at the injection site.
• Potential for incorrect interpretation if the lesions are not clearly visualized.

Benefits

• Enhanced imaging detail for more accurate diagnosis.
• Non-invasive and relatively quick procedure.
• Can guide appropriate treatment plans based on detailed lesion characterization.

Recovery

• Patients can typically resume normal activities immediately after the procedure.
• Follow-up may involve analyzing the images and discussing the findings with the referring healthcare provider.

Alternatives

• Standard ultrasound without contrast, though it may not provide as detailed information.
• MRI or CT scans, which may offer alternative imaging but involve different types of contrast agents and potentially higher costs or radiation exposure.
• Biopsy, which is more invasive but offers direct tissue diagnosis.

Patient Experience

• Patients may feel slight pressure from the ultrasound probe and a prick from the injection.
• There may be some warmth or flushing sensation as the contrast agent circulates.
• Pain is minimal and well-managed, typically not requiring any anesthesia.
