PURPOSE
When using laser guidance for cone-beam computed tomography (CBCT)-guided needle interventions, planned needle paths are visualized to the operator without the need to switch between entry- and progress-view during needle placement. The current study assesses the effect of laser guidance during CBCT-guided biopsies on fluoroscopy and procedure times.
MATERIALS AND METHODS
Prospective data from 15 CBCT-guided biopsies of 8-65 mm thoracic and abdominal lesions assisted by a ceiling-mounted laser guidance technique were compared to retrospective data of 36 performed CBCT-guided biopsies of lesions >20 mm using the freehand technique. Fluoroscopy time, procedure time, and number of CBCT-scans were recorded. All data are presented as median (ranges).
RESULTS
For biopsies using the freehand technique, more fluoroscopy time was necessary to guide the needle onto the target, 165 s (83-333 s) compared to 87 s (44-190 s) for laser guidance (p < 0.001). Procedure times were shorter for freehand-guided biopsies, 24 min versus 30 min for laser guidance (p < 0.001).
CONCLUSION
The use of laser guidance during CBCT-guided biopsies significantly reduces fluoroscopy time.
目的
在锥形束计算机断层扫描（CBCT）引导的针穿刺介入操作中使用激光引导时，可向操作者显示计划的针道，在针穿刺过程中无需在进针视图和进针过程视图之间切换。本研究评估了CBCT引导活检过程中激光引导对透视时间和操作时间的影响。
材料与方法
将采用天花板安装式激光引导技术辅助进行的15例CBCT引导的8 - 65mm胸腹部病变活检的前瞻性数据，与36例采用徒手技术进行的CBCT引导的>20mm病变活检的回顾性数据进行比较。记录透视时间、操作时间和CBCT扫描次数。所有数据均以中位数（范围）表示。
结果
对于采用徒手技术的活检，将针引导至靶点需要更多的透视时间，徒手技术为165秒（83 - 333秒），而激光引导为87秒（44 - 190秒）（p < 0.001）。徒手引导活检的操作时间较短，徒手引导为24分钟，激光引导为30分钟（p < 0.001）。
结论
CBCT引导活检过程中使用激光引导可显著减少透视时间。
