WHAT IS GUIDED TISSUE SAMPLING?
Guided Tissue Sampling is a technique that utilizes imaging to pinpoint a mass for needle aspiration.
REASON FOR THE PROCEDURE
If an abnormal mass is suspected, your doctor may request a small sample of the mass be removed to determine its composition and whether it is cancerous or benign. Guided Tissue Sampling is also useful for collecting or draining fluid (paracentesis). Guided Tissue Sampling is routinely used on breast tissue, thyroid tissue, lymph nodes, liver tissue and Baker Cysts.
At Excel Imaging, your Esse Health Radiologist uses Ultrasound imaging to locate the area of interest then applies a local anesthetic to numb the area where a hollow needle will be inserted. The Ultrasound image will help guide the placement of the needle to the mass or fluid-filled area. Tissue or fluid can then be removed for laboratory analysis.
POTENTIAL SIDE EFFECTS, RISKS, AND COMPLICATIONS
Guided Tissue Sampling is a very straight forward and safe procedure. Side effects may include infection, bleeding and soreness at the needle entry site.
