An ultrasound-guided biopsy is a medical test used to learn more about a lesion or mass. An ultrasound is an imaging method that uses high-frequency sound waves to produce precise images of your body. Using these sound waves, a needle is guided to the lesion or mass and a sample is extracted for further examination.
Who is a candidate?
This test is most often used for lymph node and liver biopsies. Good candidates include those with lesions or masses that must be examined for cancer.
What to expect
During an ultrasound-guided biopsy, local anesthesia will be used to numb the affected area. Once the ultrasound finds the abnormality and a needle extracts tissue for testing, patients may have a small amount of bleeding at the site and experience some discomfort as the numbing medication wears off. The actual insertion and removal of the needle only takes a few minutes, and the whole procedure will take about 30 minutes.
