PURPOSE
The present study evaluates the use of a laser guidance system for CT-guided intervention.
MATERIAL AND METHODS
94 cases of diagnostic biopsies and lumbar sympathectomies (54 cases with laser guidance system and 40 without) were compared.
RESULTS
Using the laser guidance system, the number of control scans decreased by 30 to 50%, and necessary corrections of needle location were reduced by a maximum of 30%. The average target deviation of the needle decreased to less than 5 mm in 50% of cases.
CONCLUSION
The laser guidance system is strongly recommended in CT-guided interventions for quality assurance and higher efficiency. The advantage is especially marked if the target area is small.
目的
本研究评估激光引导系统在CT引导介入中的应用。
材料与方法
比较94例诊断性活检和腰交感神经切除术病例（54例使用激光引导系统，40例未使用）。
结果
使用激光引导系统，对照扫描次数减少30%至50%，针位置的必要校正最多减少30%。50%的病例中针的平均目标偏差降至5毫米以下。
结论
强烈推荐在CT引导介入中使用激光引导系统以确保质量和提高效率。如果目标区域较小，优势尤为明显。
