Ultrasound Guided Biopsy

A biopsy is the removal of a small amount of tissue or a nodule so doctors can study it closely, usually to determine whether it is benign (non-cancerous) or malignant (cancerous). Ultrasound uses high-frequency sound waves to provide our radiologists with real-time images so they know precisely where to place the needle to extract a small sample. Ultrasound is also used to accurately guide the insertion of a catheter for fluid drainage from the body. Advanced Radiology performs ultrasound-guided biopsies on most organs and many other areas of the body. A partial list includes:

  • Abdomen
  • Breast – performed in the Stamford and AWIC offices – call 203-337-9729
  • Kidney – not performed in the Stratford office
  • Lung or Chest
  • Liver
  • Bone
  • Lymph nodes
  • Muscle

Approximately 60 minutes. For an ultrasound-guided biopsy, the radiologist or radiology technologist places gel on the skin of the area to be examined, and then moves the ultrasound transducer, or wand, over the skin. The area to be biopsied is cleansed and a “numbing” anesthetic may be used. A special needle is used to withdraw tissue samples to send to pathology. A dressing will be placed over the biopsy site and should remain in place for 24 hours.

If you are having an abdomen, lung or liver biopsy, take nothing by mouth after midnight before the exam. For all ultrasound-guided biopsies, you should stop taking aspirin or blood thinners five days prior to the exam.
