complex fluoroscopy-guided interventional procedures in cardiology are known to result in higher radiation doses for patients and staff.
to estimate the equivalent dose received in different regions of the cardiologist's body in catheterism (CATH) and percutaneous coronary intervention (PCI) procedures, as well as to evaluate the effectiveness of monitoring the doses in the catheritization laboratory (cath lab) using a direct ion storage dosimeter.
the Instadoseand the thermoluminescent dosimeters (TLD-100) were fixed simultaneously in the following regions of the cardiologist's body: near the eyes (left and right), the trunk region (over the lead apron) and the left ankle. Occupational doses were recorded during 86 procedures (60% CATH).
catheterization procedures showed third quartile dose values near to the left eye region equal to 0.10 mSv (TLD-100) and 0.12 (Instadose) and for intervention 0.15 mSv (TLD-100 and Instadose). The doses measured in the trunk region, over the lead apron, were about 13% higher for catheterization procedures and 20% higher for intervention procedures compared to left eye region measurements. The Wilcoxon-Mann-Whitney test was applied for unpaired data for all body regions, comparing the data obtained between the TLD-100 and Instadosedosimeters. For CATH and PCI, the responses of the TLD-100 and Instadosedosimeters are considered equal for all analysed regions (> 0.05) with the exception of the right eye region.
the Instadosepassive dosimeter can be useful as a complementary assessment in the monitoring of a cardiologist's personal occupational doses in the cath lab.
已知心脏科复杂的荧光透视引导介入手术会给患者和工作人员带来更高的辐射剂量。
估计心脏病专家在导管插入术（CATH）和经皮冠状动脉介入治疗（PCI）手术中身体不同部位所接受的等效剂量，并评估使用直接离子储存剂量计监测心导管实验室（导管室）剂量的有效性。
将Instadose剂量计和热释光剂量计（TLD - 100）同时固定在心脏病专家身体的以下部位：双眼附近（左右）、躯干区域（铅衣上方）和左脚踝。在86例手术（60%为CATH）过程中记录职业剂量。
导管插入术显示左眼区域附近的第三四分位数剂量值，TLD - 100为0.10 mSv，Instadose为0.12 mSv；介入手术中为0.15 mSv（TLD - 100和Instadose）。与左眼区域测量值相比，在铅衣上方的躯干区域测量的剂量，导管插入术约高13%，介入手术约高20%。对所有身体部位的未配对数据应用Wilcoxon - Mann - Whitney检验，比较TLD - 100和Instadose剂量计获得的数据。对于CATH和PCI，除右眼区域外，TLD - 100和Instadose剂量计在所有分析区域的响应被认为相等（>0.05）。
Instadose被动剂量计可作为监测导管室中心脏病专家个人职业剂量的补充评估手段。
