Needle tip visualization is of high importance when performing biopsies under magnetic resonance (MR) imaging control. The exact position of the needle tip is, however, often obscured by the artifact of the needle. We investigated a newly developed biopsy needle design using a diamagnetic coating for several fast MR sequences (FLASH, FISP and TSE).
