To evaluate dose reduction in vascular angiographic procedures by using fluoroscopy capture instead of digital subtraction angiography frames for documentation.
A total of 764 consecutive vascular interventional procedures performed over a period of 1 year were retrospectively analyzed with respect to the fluoroscopy time and the resulting dose-area product (DAP), the DAP of the radiographic frames, and the overall DAP.
A total of 70% of the total DAP was a result of the acquisition of radiographic frames, leaving only 30% being applied by fluoroscopy.
Fluoroscopy capture should be used for documentation whenever possible. A registry of radiation exposure should not only comprise a sufficiently large number of interventions but also different intervention types to allow the development of interventional reference levels.
通过使用透视采集而非数字减影血管造影（DSA）帧进行记录，来评估血管造影术的剂量减少。
回顾性分析了为期 1 年的 764 例连续血管介入手术，分析了透视时间和相应的剂量面积乘积（DAP）、放射帧的 DAP 以及总 DAP。
总 DAP 的 70%是由拍摄放射帧导致的，只有 30%是由透视导致的。
只要有可能，就应使用透视采集进行记录。辐射暴露登记不仅应包含足够数量的介入治疗，还应包含不同的介入类型，以便制定介入参考水平。
