title: MR-directed needle biopsies.
abstract: New generation stainless steel alloys have enabled the development of needles which can be used for MR-guided biopsies. Biopsy under MR guidance has the advantages of greater tissue contrast resolution, lack of ionizing radiation, and variable angle oblique imaging planes. The biopsy approaches and imaging techniques are described.
