A comparison of CT-stereotaxic brain biopsy techniques

The role that computed tomography plays in the stereotaxic biopsy of intracranial lesions is reviewed. The most useful techniques, apparatuses results, and complications are described. Major complications of the procedure are hemorrhage and edema. The risk of hemorrhage may be reduced by the use of angiography before stereotaxic procedures; the risk of edema may be reduced by using steroids. Design features of several representative systems are compared. Indications for this procedure are suggested.
