How Stereotactic biopsy of a brain tumour is performed?
The stereotactic frame is attached to the patient’s head and the CT scan is performed to locate the brain tumour in relation to the frame. The brain tumour is now pin point located on the CT scan using co-ordinates in three directions. These calculations are transferred to an arc system which guides the neuro surgeon to pass a needle to the brain tumour and take a bit of tumour tissue for laboratory test (biopsy- Histopathology). This avoids a major operation and big opening of the skull. The procedure is lees time consuming with less morbidity and mortality. Hospital stay is reduced to one or two days in comparison to open surgery.
