We compared eight spinal needle biopsy procedures performed with an investigational disposable real-time stereotactic device and eight spinal needle freehand biopsies in which a standard technique was used, to determine whether the investigational device added value to the procedure. The device uses a simple stereotactic diaphragm pattern to define two vector points. The procedures in which the device was used were completed in 38% less time, using 50% fewer images, with considerably improved spatial accuracy and increased operator confidence, despite the device learning curve.
我们比较了使用一种试验性一次性实时立体定向装置进行的8例脊柱穿刺活检操作和使用标准技术进行的8例徒手脊柱穿刺活检，以确定该试验性装置是否为该操作增加了价值。该装置使用简单的立体定向隔膜模式来定义两个向量点。尽管存在装置学习曲线，但使用该装置的操作完成时间减少了38%，使用的图像数量减少了50%，空间准确性显著提高，操作者信心增强。
