Increased use of magnetic resonance imaging and magnetic resonance angiography in stereotactic planning highlight some technical problems in imaging. Visualization of markers during imaging are vital in stereotactic planning. In magnetic resonance imaging-guided stereotaxy, specially designed plates are used that contain water-based copper sulfate solutions as a marker. Replacement of copper sulfate solution is usually required after some time due to precipitation and leaking. The refilling procedure is quite cumbersome and can cause technical problems in imaging. In this study, we describe copper sulfate solution mixed with a water-soluble gel as a simple but useful alternative to water-based copper sulfate resolution to ease the refilling procedure and to overcome the air bubbles.
在立体定向规划中，磁共振成像和磁共振血管造影的使用增加凸显了一些成像技术问题。成像过程中标记物的可视化在立体定向规划中至关重要。在磁共振成像引导的立体定向手术中，使用了专门设计的板，其中含有水基硫酸铜溶液作为标记物。由于沉淀和泄漏，一段时间后通常需要更换硫酸铜溶液。重新填充过程相当繁琐，并且可能在成像中导致技术问题。在本研究中，我们描述了将硫酸铜溶液与水溶性凝胶混合，作为水基硫酸铜溶液的一种简单但有用的替代物，以简化重新填充过程并克服气泡问题。
