| stereotactic instrument | Stereotaxic instrument, an apparatus attached to the head, used to localise precisely an area in the brain by means of coordinates related to intracerebral structures. (05 Mar 2000) |
| stereotactic needle biopsy | Biopsy done while breast is compressed under mammography. A series of pictures locate the lesion, and a radiologist enters information into a computer. The computer calculates information and positions a needle to remove the finding. A needle is inserted into the lump, and a piece of tissue is removed and sent to the lab for analysis. May be referred to as mammotest or core biopsy. (09 Oct 1997) |
| stereotactic radiosurgery | A radiation therapy technique that uses a large number of narrow, precisely aimed, highly focused beams of ionising radiation. The beams are aimed from many directions circling the head and meet at a specific point. (16 Dec 1997) |
| stereotactic surgery | A precise method of destroying deep-seated brain structures located by use of three-dimensional coordinates. Synonym: stereoencephalotomy, stereotactic surgery, stereotaxic surgery, stereotaxis. (05 Mar 2000) |
| stereotactic radiosurgery |
stereotaxic radiosurgery, stereotactic surgery in which lesions are produced by ionizing radiation.

| stereotactic radiosurgery |
A radiation therapy technique for brain tumors that uses a rigid head frame that is attached to the skull. The frame is used to help aim high-dose radiation beams directly at the tumors and not at normal brain tissue. This procedure does not involve surgery. Also called stereotactic external-beam radiation, stereotactic radiation therapy, and stereotaxic radiosurgery.

| stereotactic biopsy |
A biopsy procedure that uses a computer and a three-dimensional scanning device to find a tumor site and guide the removal of tissue for examination under a microscope.

| stereotactic neurosurgery |
Microsurgical intervention in deep brain structures for lesion, biopsy or implantation that is based on careful planning using a three-dimensional coordinate system established with the help of neuroimaging.

| stereotactic |
refers to use of precise coordinates to identify deep structures of the brain. The coordinates may be obtained by fitting a patient's head with a special frame and taking a CT or MRI scan. The position of the brain structures relative to the frame permits fine localization of the deep brain structures. Stereotactic methods are used during brain surgery for tremor, Parkinson's disease, and dystonia. These brain structures are located with precise, three-dimensional coordinates.
