title: Intraoperative and outpatient echoencephalography through a burr hole.
abstract: Ultrasound images of the brain were obtained intraoperatively and on an outpatient basis through a burr hole. The patient's tumor was well visualized, prior to biopsy, after biopsy, and during radiation therapy treatment. The ultrasound images correlated closely to the CT scan findings.
