在进行核磁检查时,身上不能有金属制品,否则金属会受检查磁场影响移动,可能造成患者受伤,但很多人不知道这点。由于在核磁共振机器及检查室内存在非常强大的磁场,因此,装有心脏起搏器的病人,以及血管手术后留有金属夹、金属支架者,绝对严禁做核磁检查。否则,由于金属受强大磁场的吸引而移动,将可能产生严重后果以致发生生命危险。检查室内就如同一个大磁铁,并且吸力非常强劲,很多小的金属物件会被机器迅速吸附过去,这个速度足以把机器打穿。
During the magnetic resonance imaging examination, the body can not have metal products, or metal will be affected by the inspection magnetic field movement, may cause injury to patients, but many people do not know this. Due to the presence of a very strong magnetic field in MRI machines and examination rooms, patients with pacemakers and metal clips and metal stents left after vascular surgery are strictly forbidden to do magnetic resonance imaging. Otherwise, due to the attraction of the metal by a strong magnetic field, the metal may have serious consequences that may lead to life-threatening situations. The inspection room is like a large magnet, and the suction is very strong, many small metal objects will be quickly absorbed by the machine in the past, this speed is enough to wear the machine.
