Needles, Biopsy, Brain

Definition : Biopsy needles designed to obtain tissue samples from the brain. These needles typically include an inner needle that is attached to an external aspiration syringe and an outer needle (cannula) to cut the aspirated tissue that is extracted by pulling out the inner needle. Brain biopsy needles are used to perform biopsies of cystic lesions and suspected tumors. Needles that can be used in stereotactic procedures, either under radiographic or magnetic resonance imaging guidance, are available.
