We present a simple but efficient technique for marking the site of a stereotactic biopsy. This is done by a radiopaque Barium impregnated silicone sphere, which is introduced through the stereotactic cannula and placed at the target point. This allows a postoperative check of the target point by computer tomography or Magnetic Resonance Imaging and offers a landmark for further stereotactic intervention as well as for planning of high precision radiotherapy. Moreover it gives information about the growing direction of a tumour. The silicone spheres are well tolerated; no complications have occurred so far.
我们介绍一种用于标记立体定向活检部位的简单而有效的技术。这是通过一个不透射线的钡浸渍硅胶球来完成的，该球通过立体定向套管引入并放置在靶点处。这使得术后可通过计算机断层扫描或磁共振成像对靶点进行检查，并为进一步的立体定向干预以及高精度放射治疗计划提供一个标志物。此外，它还能提供有关肿瘤生长方向的信息。硅胶球耐受性良好；到目前为止尚未发生并发症。
