Achieving the required accuracy during such relatively straightforward procedures as tumour biopsy or abscess aspiration remains a challenge especially for the more junior neurosurgeon. A study comparing freehand biopsy with ultrasound-guided biopsy is presented. The use of intraoperative ultrasound increases the accuracy at the expense of a slightly longer operating time. Diagnostic tissue was always obtained using this technique.
在诸如肿瘤活检或脓肿穿刺抽吸等相对简单的手术过程中达到所需的准确性，尤其是对于经验较少的神经外科医生来说，仍然是一项挑战。本文展示了一项比较徒手活检与超声引导活检的研究。术中超声的使用提高了准确性，但代价是手术时间略有延长。使用该技术总能获取到诊断性组织。
