Ultrasound-guided needle biopsies in deep cerebral lesions

Ultrasound-guided brain biopsies through a single burr hole are controlled by real-time imaging and do not require contrast media. The procedure is straightforward and takes les than one hour. However, it has been reported that this technique may be inadequate for deep lesions, especially lymphomas. Methods: We analysed 57 ultrasound guided brain tissue biopsies performed in our department within the last two and a half years. Through a single burr-hole with a diameter of 11mm, a 6×9mm ultrasound probe was used to perform needle biopsies of different brain regions. The needle was attached to the probe by a guidi…
