• An ultrasound-guided needle biopsy procedures main motto is to obtain a tissue sample of an abnormality discovered on a radiology scan and it is an outpatient procedure. This is one main type of “image-guided” biopsy, which unites the use of both ultrasound with either a Fine Needle Aspiration or Core Needle Biopsy. An ultrasound is radiology tests which create pictures of internal organs by using sound waves. No radiation is used by ultrasound.

  • The most important is to remember that not just because of something is abnormal does not mean it is tumor or cancer. In fact, the common abnormalities establish on radiology tests are benign (non-cancerous).

  • These lesions are mostly too small or too deep that can be felt by your doctor’s hands when he/she makes an attempt to take a biopsy. For this reason, image-guidance is recommended to guide the needle to the accurate location. Ultrasound-guided biopsies are usually performed as an outpatient procedure.

  • This procedure may also be combined with endoscopy or bronchoscopy when tumors are inside the GI tract or the lungs. These are correspondingly known as endoscopic ultrasound (EUS) or endobronchial ultrasound (EBUS).


  • An ultrasound-guided biopsy is usually performed under local anesthesia (by using numbing medicine like lidocaine).

  • An ultrasound was performed to locate the exact abnormality and it is used to direct the needle into the lesion. The needle is then detached and contains tissue from the abnormality.

  • After the tissue is collected, the tissue sample is placed on a glass slide for a pathologist to study and evaluate.

  • A pathologist who expertise in microscopic studies of the tissues will examine. After the pathologist has recognized a diagnosis, a report is generated for your doctor.

  • The actual insertion of the needle usually takes only a few minutes. The complete procedure will take about 30 minutes.

  • This can create slightly uncomfortable but resolves over few days.
