Intervention: Needle biopsy, ablation score high in tumors

March 01, 1997

Over the past 15 years, improvements in biopsy needle design, sampling technique, and expertise of radiologists and cytopathologists have developed in concert with imaging technologies to make percutaneous needle biopsy (PNB) the most common interventional radiologic procedure. With skills refined from performing PNB, radiologists can now use a new and promising outgrowth of this technique-percutaneous tumor ablation-to safely and accurately place needles into a variety of malignant lesions to deliver local treatment.
