MRI-Guided Vacuum-Assisted Breast Biopsy (VAB)
What is Vacuum-Assisted Biopsy (VAB) with Breast MRI?
Vacuum-Assisted Biopsy (VAB) with Breast Magnetic Resonance Imaging (MRI) is a minimally invasive procedure used to obtain samples of suspicious breast tissue, guided by magnetic resonance images. This technique allows for precise sampling of specific areas of the breast that are not easily accessible with other biopsy techniques.
What is this diagnostic test used for?
VAB with Breast MRI is used for:
- Diagnosing suspicious breast lesions: Allows for obtaining tissue samples for analysis to determine if they are benign or malignant.
- Evaluating lesions detected on breast MRI: Used to confirm or rule out the presence of cancer in lesions visualized on MRI.
- Obtaining samples from small or deep lesions: Allows access to lesions that are difficult to biopsy with other techniques.
Benefits of high technology in VAB with Breast MRI
VAB with Breast MRI uses a special needle inserted into the breast, guided by real-time magnetic resonance images. The needle is connected to a vacuum system that helps aspirate tissue samples. This allows for obtaining multiple samples with a single needle insertion, which reduces patient discomfort and increases diagnostic accuracy.
How is the procedure performed?
The VAB with Breast MRI procedure involves:
-
Preparation:
If you are allergic to any medication, especially local anesthesia, it is important to inform your doctor. You should also mention if you are taking aspirin, anticoagulants, or herbal supplements. On the day of the test, avoid applying creams, lotions, or deodorants to the breast area. Additionally, try to wear comfortable, easy-to-remove clothing.
-
During the test:
You will be asked to lie face down on the MRI table, with your breast placed in a special opening. To numb the area where the biopsy will be performed, local anesthesia will be administered. Then, the radiologist will insert a needle guided by the MRI images and extract several tissue samples using a vacuum system. A mammogram will be performed to confirm the correct placement of a marker clip at the biopsy site. In total, the procedure usually lasts between 30 and 60 minutes.
-
After the test:
After the biopsy, pressure will be applied to the area to stop bleeding, and a compression bandage will be placed. If you feel discomfort, you can take over-the-counter pain relievers. It is important to avoid strenuous physical activities for the next 24 hours. Contact your doctor if you notice signs of infection, such as fever, redness, or discharge in the area. The results will be available in a few days, and your doctor will explain the findings and, if necessary, recommend appropriate treatment.
Recommendations for the test
If you have claustrophobia, inform your doctor before the test so they can help you feel more comfortable. It is also important to inform your doctor if you have breast implants. To ensure the best results, follow all medical instructions before, during, and after the procedure.
Are there any risks?
VAB with Breast MRI is a safe procedure, but there are some risks:
- Bleeding: There may be minor bleeding at the biopsy site.
- Hematoma: A hematoma may form in the biopsy area.
- Infection: There is a small risk of infection at the biopsy site.
- Pain: You may feel mild pain or discomfort after the biopsy.
For your test to proceed smoothly, we ask that you arrive in advance of your scheduled time. This will allow us to complete the necessary administrative and clinical preparation.
Before the test, we will provide you with the Informed Consent form, a document with important information that you must read and sign.
If your appointment is for a Magnetic Resonance Imaging (MRI), it is crucial that you inform us about the presence of pacemakers, metallic objects, prostheses (including dental), tattoos, or medication infusion devices, such as insulin pumps.
These diagnostic tests are very safe, but as with any medical procedure, there is a minimal possibility of incidence.
