Stereotactic neurosurgery requires the utmost precision. This can be achieved with modern imaging methods, provided special localisers are used which produce reference points for the calculation of stereotactic coordinates. Since not every substance can be visualised in every imaging modality, various localisers are normally used. These contain, for example, thin steel wires for CT or copper sulphate for MRI. By using a mixture of jopamidol and copper sulphate at a ratio of 1:1, it is possible to make the reference points of a localiser visible in both CT as well as in MRI. In this way, the entire stereotactic planning can be carried out using only one single localiser. This not only simplifies the procedure, it also reduces costs.
立体定向神经外科手术需要极高的精度。借助现代成像方法可以实现这一点,前提是使用特殊的定位器,这些定位器能产生用于计算立体定向坐标的参考点。由于并非每种物质都能在每种成像模态中显影,通常会使用各种定位器。例如,这些定位器包含用于CT的细钢丝或用于MRI的硫酸铜。通过以1:1的比例使用碘帕醇和硫酸铜的混合物,可以使定位器的参考点在CT和MRI中都可见。这样,仅使用一个定位器就可以完成整个立体定向规划。这不仅简化了程序,还降低了成本。
