为了证明一个简单的激光标记系统（LMS）的有效性，在目标定义以及检查程序的CT引导下的干预，130例诊断性活检和腰交感神经切除术进行了比较。75例使用LMS，55例使用简单的交叉网格。利用LMS，可以计划、准确演示介入参数（皮肤位置、长度和角度），并且可以在整个手术过程中检查针的位置。因此，必要的控制扫描的数量减少到30%，并且针位置的校正减少到大约30%。50%的病例穿刺针的平均靶点偏差小于5 mm，介入手术时间明显缩短。可以得出结论，LMS推荐在CT引导的干预质量保证，剂量减少，并改善处理。在小靶体积、倾斜针路径和倾斜机架的情况下，这将是特别有利的。
To prove the usefulness of a simple laser marker system (LMS) in target definition as well as examination procedure for CT-guided interventions, 130 cases of diagnostic biopsies and lumbal sympathectomies were compared. In 75 cases LMS and in 55 cases a simple crossgrid was used. Taking advantage of the LMS, the parameters of intervention (cutaneous location, length, and angle) can be planned, exactly demonstrated, and it is possible to check the needle position during the whole procedure. Thus, the number of necessary control scans decreased to 30 %, and corrections of needle location were reduced to approximately 30 %. Moreover, the average target deviation of the needle decreased below 5 mm in 50 % of cases, and the duration of interventional procedure was reduced considerably. It can be concluded that LMSs are recommended in CT-guided interventions for quality assurance, dose reduction, and improvement of handling. It will be especially advantageous in cases of small target volume, oblique needle path, and tilted gantry.
