Guided biopsy: A stereotactic biopsy uses three-dimensional coordinates to guide the biopsy needle to precisely the right place to sample a tissue abnormality. Almost all of these are brain biopsies, in which a small hole is drilled in the skull and the needle is passed into the brain on a predetermined trajectory to arrive at the exact right spot, previously determined from imaging.
