We aimed to assess whether insulating covers and warming systems cause artifacts in fluoroscopy, and whether they alter the radiation dose.
Eight insulating and warming systems were wrapped around the phantom in order to obtain images in fluoroscopy, and to measure the absorbed and scattered radiation dose. A dosimeter, endovascular catheters, and stents were placed into a phantom. The other dosimeter was placed outside of a C-arm table, at the operator's and anesthesiologist's locations.
Most of the insulating covers did not cause artifacts in the fluoroscopy and led to a significant decrease in both the absorbed and scattered radiation dose. The highest decrease in the absorbed dose was observed with metalized foil (- 2.09%; p = 0.001) and in the scattered dose with Helios cover (- 55%; p < 0.001). Only one heating system (Ready Heat combined with Hypothermia Prevention and Management Kit cover) caused significant artifacts and increased radiation up to 99% (p < 0.001).
Thermal insulation may be maintained during X-ray-guided emergency endovascular procedures in trauma victims. Self-heating blankets should be replaced with another warming system.
我们旨在评估隔热罩和加热系统是否会在透视检查中产生伪影，以及它们是否会改变辐射剂量。
将八个隔热和加热系统包裹在体模周围，以便在透视检查中获得图像，并测量吸收和散射的辐射剂量。将一个剂量计、血管内导管和支架放置在体模中。另一个剂量计放置在 C 臂工作台外，在操作员和麻醉师的位置。
大多数隔热罩在透视检查中没有产生伪影，并导致吸收和散射辐射剂量显著降低。金属化箔片（-2.09%；p=0.001）导致吸收剂量的最大降低，而 Helios 罩（-55%；p<0.001）导致散射剂量的最大降低。只有一种加热系统（Ready Heat 与 Hypothermia Prevention and Management Kit 罩组合）会导致明显的伪影，并将辐射增加高达 99%（p<0.001）。
在创伤患者的 X 射线引导的紧急血管内手术中，可以保持热绝缘。自热毯应更换为另一种加热系统。
