The goals of this study is to evaluate and compare the irradiation received by the practitioner when performing percutaneous vertebroplasty or kyphoplasty guided by CT and fluoroscopy, for precise anatomical sites.
For each intervention, radiothermoluminescent dosimeters were carefully positioned on both orbitals, both hands, and both ankles of the practitioner.
Twenty-four vertebroplasties were performed in 18 patients and nine kyphoplasties on seven patients. The anatomical site that is most exposed to radiation is the right hand. The two other sites subjected to irradiation are the left hand and the left orbital. This study demonstrates a significant correlation between the irradiation dose and fluoroscopy duration, reflecting both the quantity of primary-beam radiation and backscattered radiation.
The radiation dose to radiologist is more important for kyphoplasty procedures than vertebroplasty.
本研究的目的是评估和比较在CT和荧光透视引导下对精确解剖部位进行经皮椎体成形术或后凸成形术时术者所接受的辐射。
对于每种干预措施,将放射热释光剂量计小心地放置在术者的双侧眼眶、双手和双踝处。
对18例患者进行了24次椎体成形术,对7例患者进行了9次后凸成形术。辐射暴露最多的解剖部位是右手。另外两个受照射的部位是左手和左眼眼眶。本研究表明照射剂量与荧光透视持续时间之间存在显著相关性,反映了原发射线辐射和反向散射辐射的量。
对于后凸成形术,放射科医生所接受的辐射剂量比椎体成形术更重要。
