Endovascular surgical neuroradiologists can receive a substantial amount of occupational radiation exposure. We evaluated the amount of radiation exposure that results from the practice of performing hand injections during digital subtraction angiography (DSA). The primary operator can significantly decrease the radiation dose by leaving the room for DSA procedures. However, the total radiation dose for the primary operator is relatively low and is certainly within allowable regulatory limits when extrapolated to a yearly dose.
血管内手术神经放射科医生可能会受到大量的职业辐射暴露。我们评估了在数字减影血管造影(DSA)期间进行手动注射操作所导致的辐射暴露量。主操作者可以通过在DSA操作期间离开房间来显著降低辐射剂量。然而,主操作者的总辐射剂量相对较低,当推算到年剂量时肯定在允许的监管限度内。
