Many interventionalists face physical challenges almost daily for years or decades. The burden of assuming awkward positions while carrying extra weight can take its toll on the musculoskeletal system to such an extent that the career is ended or modified to exclude procedural aspects. The proliferation of lighter aprons has unfortunately resulted in reduced protection with poor correlation of protection to labeling due to the inadequacies of testing methods for nonlead materials. The protective quality of the non-leads is not superior to lead-containing composites on a weight basis, and the user no longer knows how well they are protected unless buying aprons containing lead. Various useful methods and shields that may reduce radiation exposure are supported by the floor, ceiling, table, or patient. The suspended personal radiation protection system is a recent development which provides substantially greater radiation protection than conventional lead aprons combined with other shields, while also taking all of the weight off of the operator. It is composed of an expansive and thick (1mm Pb equiv) apron with a large face-shield to protect the neck, head, and eyes, and is suspended overhead to provide motion in the x, y, and z planes. Exposures may also be substantially reduced by leaving the area during acquisition sequences and use of power injectors.
多年甚至数十年来,许多介入放射科医生几乎每天都面临身体挑战。在承受额外重量的同时保持别扭姿势所带来的负担,会对肌肉骨骼系统造成极大损害,以至于不得不结束职业生涯或改变工作内容以排除操作环节。不幸的是,由于非铅材料测试方法的不足,更轻便防护围裙的大量使用导致防护效果降低,且防护效果与标签之间的关联性较差。在重量基础上,非铅防护用品的防护质量并不优于含铅复合材料,用户除非购买含铅围裙,否则不再清楚自己受到了何种程度的防护。地板、天花板、桌子或患者可以支撑各种有助于减少辐射暴露的有用方法和防护装置。悬挂式个人辐射防护系统是一项最新发明,与传统铅围裙及其他防护装置相比,它能提供更强的辐射防护,同时还能完全消除操作人员的负重。该系统由一个宽大厚实(相当于1毫米铅当量)的围裙和一个用于保护颈部、头部及眼睛的大型面罩组成,悬挂在头顶上方,可在x、y和z平面内移动。在采集序列期间离开操作区域以及使用动力注射器也可大幅减少辐射暴露。
