Ultrasound Guided Biopsy
An ultrasound guided biopsy is performed to obtain a tissue sample from an area of abnormality identified on a mammogram or breast ultrasound procedure.
During an ultrasound guided biopsy:
- You will be asked to lie on your back on the examination table with your arm extended behind your head while a warm gel will be applied to your breast. The gel helps the sound waves travel from the machine into your breast tissue.
- A transducer, which is a small microphone-like device, will be placed on your breast. This will be painless, however, you may feel mild pressure from the transducer.
- The technologist will locate the lesion to be biopsied for the radiologist.
- The radiologist will numb the area to be biopsied with an injection of local anesthetic into your breast, using a small needle. You may feel a slight sting in your breast at the injection site.
- After the local anesthetic has taken effect, the radiologist will insert the biopsy needle into your breast and samples will be taken.
- When the radiologist confirm that all the correct samples have been retrieved, a titanium clip will be deployed into the biopsy site to mark it in future mammograms.
- Ultrasound images will be obtained to confirm location of the clip.
- Pressure will be applied to the biopsy site and a sterile dressing will be applied.
