C8908 Magnetic resonance imaging without contrast followed by with contrast, breast; bilateral

Name of the Procedure:

Common Names: Breast MRI, Bilateral Breast MRI

Technical Terms: Magnetic Resonance Imaging (MRI) without contrast followed by with contrast, bilateral breast (C8908).

Summary

This procedure involves using a magnetic resonance imaging (MRI) machine to take detailed pictures of both breasts. Initially, images are taken without any contrast material. Subsequently, a contrast dye is injected, which helps to highlight certain areas in the breast tissue, providing more detailed images.

Purpose

Medical Conditions Addressed:

• Detection of breast cancer
• Evaluation of abnormalities found on mammograms or ultrasounds
• Monitoring for recurrence of breast cancer or other abnormalities

Goals/Expected Outcomes:

• Accurate detection and assessment of breast abnormalities
• Better planning for biopsies or surgeries
• Monitoring of treatment efficacy in breast cancer patients

Indications

Symptoms/Conditions Warranting the Procedure:

• Palpable breast lumps not clarified by other imaging techniques
• High-risk patients with a strong family history of breast cancer
• Inconclusive results from mammograms or ultrasounds
• Planning for breast cancer treatment

Patient Criteria/Factors:

• Women with dense breast tissue
• Previously diagnosed breast cancer patients for surveillance
• Patients with breast implants

Preparation

Pre-Procedure Instructions:

• Remove all metallic objects as MRI uses a strong magnetic field
• Inform the doctor of any metal implants or electronic devices
• Fasting is usually not required

Diagnostic Tests/Assessments:

• Blood tests might be required if kidney function needs to be checked (due to contrast dye)

Procedure Description

1. The patient changes into a hospital gown and removes all metal objects.
2. The patient lies face down on a specialized MRI table with openings for the breasts.
3. Initial MRI scans are taken without contrast.
4. The patient remains still while a contrast agent (usually gadolinium) is injected through an IV.
5. Additional MRI scans are performed after the contrast injection to get enhanced images.
6. The technologist monitors the procedure from another room, communicating via an intercom.

Tools/Equipment:

• MRI machine
• IV line for contrast dye
• Contrast agent (gadolinium)

Anesthesia/Sedation: Not typically required unless the patient experiences significant anxiety or discomfort.

Duration

The entire 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
• MRI technologist
• Nursing staff (for intravenous contrast administration)

Risks and Complications

Common Risks:

• Discomfort from lying still for an extended period
• Mild reactions to contrast dye (e.g., nausea, headache)

Rare Risks:

• Allergic reactions to contrast dye
• Nephrogenic systemic fibrosis in patients with severe kidney problems

Possible Complications and Their Management:

• Moderate allergic reactions can be managed with medications such as antihistamines
• Ensure adequate hydration post-procedure to help flush out the dye

Benefits

Expected Benefits:

• Highly detailed images of breast tissue
• Improved accuracy in diagnosing and treating breast conditions

Realization Time:

• Immediate imaging results, but full interpretation may take a few days by the radiologist

Recovery

Post-Procedure Care:

• Normal activities can typically be resumed immediately
• Staying hydrated to assist in contrast dye excretion

Expected Recovery Time:

• No significant recovery time needed

Restrictions/Follow-Up:

• Follow-up appointments may be scheduled to discuss results with the healthcare provider

Alternatives

Other Treatment Options:

• Mammography
• Ultrasound
• 3D Tomosynthesis

Pros and Cons of Alternatives:

• Mammography: less expensive, less detailed images
• Ultrasound: useful for dense breasts, but less comprehensive
• 3D Tomosynthesis: better than standard mammography for dense tissue, not as detailed as MRI

Patient Experience

During the Procedure:

• May hear loud thumping or tapping from the MRI machine
• Must remain very still for accurate results
• IV needle insertion may cause slight discomfort

After the Procedure:

• Generally no significant pain
• Mild discomfort from lying still
• Hydration recommended to help flush out contrast dye
