MRI-guided Vacuum-Assisted Breast Biopsy
What is an MRI-guided Vacuum-Assisted Breast Biopsy (VABB)?
A Vacuum-Assisted Breast Biopsy (VABB) with Magnetic Resonance Imaging (MRI) is a minimally invasive procedure used to obtain samples of suspicious breast tissue, guided by magnetic resonance imaging. This technique allows precise samples to be obtained from specific areas of the breast that are not easily accessible with other biopsy techniques.
What is this diagnostic procedure for?
MRI-guided VABB is used to:
- Diagnose suspicious breast lesions: It allows tissue samples to be obtained for analysis and to determine whether they are benign or malignant.
- Evaluate lesions detected in a breast MRI: It is used to confirm or rule out the presence of cancer in lesions seen on a breast MRI.
- Obtain samples from small or deep lesions: It allows access to lesions that are difficult to obtain with other biopsy techniques.
Benefits of the latest technology in MRI-guided VABB
MRI-guided VABB uses a special needle that is inserted into the breast, guided by real-time magnetic resonance imaging. The needle is connected to a vacuum system that helps to aspirate the tissue samples. This allows multiple samples to be obtained with a single needle insertion, reducing discomfort for the patient and increasing diagnostic accuracy.
MRI-guided VABB involves:
-
Preparation:
If you are allergic to any medication, especially to local anesthesia, it is important that you inform your doctor. You should also mention if you are taking aspirin, anticoagulants (blood thinners), or herbal supplements. On the day of the procedure, avoid applying creams, lotions, or deodorants to the breast area. Also, try to wear comfortable clothes that are easy to take off.
-
During the procedure:
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 is to be performed, you will be given local anesthesia. Next, the radiologist will insert a needle guided by the MRI images and extract several tissue samples using a vacuum system. The correct placement of a marker clip at the biopsy site will be confirmed via a mammogram. In total, the procedure usually lasts between 30 and 60 minutes.
-
After the procedure:
After the biopsy, they will apply pressure to the area to stop the bleeding and apply a compression bandage. If you feel any discomfort, you can take over-the-counter pain relievers. Strenuous physical activity should be avoided 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 after a few days and your doctor will explain the findings and, if necessary, recommend the appropriate treatment.
Recommendations for the procedure
If you are claustrophobic, let the doctor know before the procedure 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 the instructions before, during, and after the procedure.
Are there any risks?
An MRI-guided VABB is a safe procedure, but there are some risks:
- Bleeding: There may be a small amount of bleeding at the biopsy site.
- Bruising: A bruise may form in the biopsy area.
- Infection: There is a small risk of infection at the biopsy site.
- Pain: You may experience mild pain or discomfort after the biopsy.
To ensure your procedure runs smoothly, we ask that you arrive before the scheduled time. This will allow us to complete the necessary administrative and clinical preparation.
Before the procedure, we will give you the Informed Consent form, a document with important information that you must read and sign.
If your appointment is for an MRI, it is crucial that you inform us about the presence of pacemakers, metallic objects, prostheses (including dental prostheses), tattoos, or drug infusion devices such as insulin pumps.
