金属异物(FBS)是核磁共振检查中的安全隐患。在这里，我们描述了一个童年早期的男孩，他在研究大脑核磁共振时发现了意想不到的铁磁性Fb。安全预防措施包括书面和口头安全筛查清单，以及在有组织的安全暂停期间进行目视检查。在介绍扫描仪的过程中，他被抬起来看了看内孔。工作人员意识到有一个物体飞进了钻孔。孩子伸手去摸耳朵，在内孔里发现了一个直径5 mm的滚珠轴承。这名儿童没有受到任何外部伤害。我们引入了0.1T的手持式磁铁来检查父母不知道的金属FBS。FBS是儿科急诊科常见的表现，尤其是在年幼的儿童或有认知或行为问题的儿童中。此病例强调了儿科MRI扫描中安全筛查的重要性，以及它的易错性。
Metallic foreign bodies (FBs) are a safety risk during MRI. Here, we describe a boy in early childhood with an unexpected ferromagnetic FB discovered during a research brain MRI. Safety precautions included written and oral safety screening checklists and visual check during a structured safety pause. During introduction to the scanner, he was lifted to look at the bore. Staff became aware of an object flying into the bore. The child reached for his ear, and a 5 mm diameter ball bearing was found in the bore. The child had no external injury. We have introduced a 0.1 T handheld magnet to check for metallic FBs not known to the parent. FBs are a common paediatric emergency department presentation, particularly in younger children or those with cognitive or behavioural problems. This case highlights the importance of safety screening in paediatric MRI scanning, along with its fallibility.
