Needle biopsy of bone.

Abstract

Percutaneous trephine biopsy can be performed by the well-trained radiologist. The procedure is indicated in patients with disseminated neoplastic disease or infection. Using radiographic studies and radionuclide scans, the safest and most accessible site is chosen. The instrument must be meticulously placed in the lesion under fluoroscopic control for a high rate of recovery of diagnostic material.
